Smartphones with 2 SIM cards. Dual SIM technology - everything you need to know

We don’t remember who invented the combined slots, but there is reason to believe that the author of this horror is a Chinese company with a name starting with the letter H. some smartphones do not allow using two SIM cards and a memory card at the same time.

Manufacturers can understand: combined slots (SIM + SIM or SIM + MicroSD to choose from) are cheaper to manufacture, and they also take up less space in the case than three separate slots at once. What is important: we will save on an extra slot - we will install a slightly more capacious battery.

In general, you can understand them, but you can hardly forgive them. Because combo slots are extremely inconvenient. Especially if the device does not have 64 or 128 GB of memory, like the flagships, but only 16. Of these, the system eats up 3-4 more, and a user who needs two SIM cards is left with a pitiful 10-odd "gigs" ... Well, where does that go? That's right, nowhere. And so we have collected in this review several smartphones of different classes, offering just separate slots for two SIM-cards and a MicroSD flash drive.

(27 990 rubles)

A curious upper-middle class smartphone in a glass case, with a USB Type-C port, a high-quality AMOLED screen and a good camera. Expensive, of course, in comparison with analogs, if you compare the characteristics "on paper". However, the high price is justified by some pleasant moments, for example, the presence of protection against water and dust according to the IP68 standard and those separate slots. If you still want to save money, look towards the Galaxy A5 2017 - it's a little simpler and cheaper. But on the Galaxy A3 2017, if you need exactly three slots, you shouldn't look: there are two of them.

(12 990 rubles)

A mid-range device from the revived Nokia this year. Pros: of course, the right slots, as well as "" Android with guaranteed updates for several years and a nice metal case. The model does not have very bright features, but in general it is a good workhorse for those who still believe in Nokia. And yes, as an alternative, you can consider - this device is simpler in all respects, but it still has three card slots.

(12 990 rubles)

Motorola employs the right people: what's in it, what's in the arms of the G5 Plus, that the Moto E series devices use separate SIM and MicroSD slots. We included the Moto E Plus in this review, since this device also has a powerful 5000 mAh battery. The case is metal, the chipset ... But with the chipset, everything is complicated: a simpler version with the MediaTek platform is supplied to Russia, while a more powerful version with the Qualcomm chipset is supplied to some other countries. If you are visiting the USA, buy Moto E Plus there.

(16 990 rubles)

"Frameless" middle class with an aspect ratio of 18: 9, reminiscent of the two flagship smartphones of the Korean company - V30 and G6. This is what makes it interesting, being otherwise a fairly simple solution. Even an NFC chip is missing. However, for those who want to get NFC and a larger amount of RAM (3 instead of 2 GB), there is a slightly more expensive option.

(RUB 21,990)

Previously, Sony used the correct "three-card" layout in almost all of its models, but recently the Japanese have relaxed somewhat. However, the Xperia XA1 is a pleasant exception, there are exactly three slots here. The smartphone also has a 2300 mAh battery, a 23-megapixel camera, a 5-inch HD-screen and a mid-range MediaTek chipset. But the main thing, of course, is the so-called "sony-style": the design of the Xperia XA1 really differs from smartphones from other manufacturers, which can often be confused with each other.

(9 990 rubles)

In recent years, Xiaomi has stubbornly followed the “SIM + SIM or SIM + MicroSD” rule, but in the Redmi Note 5A model it has made an exception. A simple version of this device is supplied to Russia, that is, without a fingerprint scanner, with medium-quality cameras and 16 GB of internal memory. But it costs quite cheap, being one of the most affordable smartphones from the Xiaomi line.

(13 900 rubles) /

And again a device with a 5000 mAh battery - that is, "long-playing". On the one hand, this is one of the simplest devices in the Zenfone 4 family, on the other hand, it has a lot of interesting things. Here you have the aforementioned battery, and three slots, and a dual rear camera. The principle of its operation is approximately the same as that of the LG models - one wide-angle lens, which allows you to capture large objects from a short distance.

Previously, if we needed to have two numbers, for example, one private (home) and the other corporate (work), we used two phones. It is now possible to use Dual SIM technology, which allows you to use two SIM cards at the same time on one device.

Not all users are aware that there are several variants of this technology, and smartphones with two SIM cards are cheaper than buying two phones. Many popular models of Xiaomi smartphones support 2 SIM cards. In this article, we will explain what is the difference between different Dual SIM standards and which one is better.

Dual SIM support is a feature that allows you to use two numbers at the same time on one smartphone. This is the perfect solution for combining work and personal numbers on one device.

SIM cards and numbers do not have to be from the same operator. It also doesn't matter if it's a standard SIM, as you can cut it out or use an adapter.

The Dual SIM function is convenient to use abroad. To insert a local operator's card into the second slot and be able to save on calls home.

Dual SIM is also a way to use the services of different operators: for example, the first one with an attractive mobile internet offer, and the second one with an inexpensive unlimited package for calls and SMS. With such a smartphone, there is no need to look for a compromise - which tariff or operator to choose? We can select the offers of mobile operators that suit our needs.

Types of support for two SIM cards (Dual SIM)

Passive mode

This is the oldest and easiest way to support two SIM cards in phones. The first models with this function allowed two SIM cards to be enabled, but only one of them could be active at the same time. The second was in passive mode.

When changing the map, most often you need to select the appropriate option in the settings and restart the device. This mode is rare nowadays and is mostly known from older Nokia phones.

Standby (Dual SIM Standby - DSS)

In this mode, both cards use the same GSM antenna built into the smartphone. They remain in standby mode and are active until a voice call is made, an SMS is sent, or there is no Internet connection using one of them.

Standby mode is the most popular and is used even for the cheapest Chinese smartphones. The disadvantage of this solution is faster battery drain.

Active mode (Dual SIM Active - DSA)

It is currently the most advanced and least common mode. Smartphones with active dual SIM have two separate GSM antennas, so that both cards in the device can be active all the time - the first one works even during an ongoing voice call.

This technology is used in flagship smartphone models, where the price of the device justifies the quality of its work.

What type of support for two SIM cards to choose?

Considering all of the above features, the best seems to be "Standby" or DSS (Dual SIM Standby). It is available in most Xiaomi devices. Support for two SIM cards will not interfere with everyday use of the smartphone.

The ability to support 2 SIM cards at the same time is a useful option for business people who sometimes have to carry 2 phones. With a smartphone with two card slots, this is no longer necessary. However, the market is full of failed phones and should be avoided. We have compiled the TOP of the best models based on customer reviews.

More or less expensive models

1st place - Xiaomi Redmi Note 3 Pro (12-13 thousand rubles)

The current price of this model is 12-13 thousand rubles. True, there are stores in which it costs about 18 thousand. We recommend that you bypass such sellers.

Specifications:

Here the memory card slot is combined with the SIM card slot. Therefore, when using a memory card, you will not be able to use a second SIM card. But 32 GB of native memory should be enough anyway.

This phone was announced in early 2016. He managed to collect a lot of good reviews during his time in the market. There is an excellent screen, high performance (even modern games "pulls" without any brakes and friezes), it looks great. The cameras take good pictures, but they can't compete with the flagship cameras. As for the battery, you cannot put it down in a day, no matter how actively you use your smartphone. Perhaps this is the ideal option for your money.

A possible drawback is a weak screen. It is ready to crack, crash, split into atoms when dropped, and its replacement will cost 2,000 rubles. So use it carefully and be sure to stick a protective film on it.

2nd place - Huawei Honor 4c (9-12 thousand rubles)

Of course, this is one of the best phones from Huawei, and it deserves to take second place in this rating. The device can be found in stores at a price of 9-12 thousand rubles, and this is a fairly wide price range. Therefore, we strongly recommend looking for a device in stores, where its price is in the region of 9-10 thousand.

Specifications:

High performance (8-core processor), clear and loud sound, non-buggy, convenient and bright. It looks great and boasts high shock resistance (unlike the previous phone in the ranking). All of this justifies its price tag. It also supports 2 SIM cards and gets a lot of positive reviews, which puts it on the 2nd place.

There are also disadvantages. First of all, these are mid-range cameras, which are commonplace. They take good pictures during daylight hours, but they cannot boast of anything special. There are also complaints from users about poor GPS performance (sometimes it does not correctly determine the location) and insufficient memory to store data. Only 8 GB for a smartphone is not enough, so you have to use a flash drive. The battery capacity is small - this is a minus, but it holds the charge well. With moderate use, the smartphone is enough for 2 days of work.

Overall, the price / performance ratio is good. We recommend buying, but take a close look at the cons. If they are critical for you, then you have looked after another model.

Video review:

3rd place - ASUS Zenfone 2 Laser ZE500KL (10,500-13,000 rubles)

This is a successful model with positive reviews and support for two SIM cards.

Specifications:

Reliability, design, price / quality ratio, sound and assembly are the main advantages of the phone. The screen can also be attributed to the merits - it is juicy and bright. But the camera leaves much to be desired. To get a good sharp picture, you need to keep the phone perfectly level (no shaking), which is sometimes difficult to do. Dynamic shots will almost always be blurry.

In general, the device is reliable: it has been working for users for over a year and has no complaints at all. The assembly is excellent: nothing loosens, does not stagger, does not creak. It supports 2 SIM cards and fits perfectly into the 3rd place in this rating.

Videooverview:

4th place - Samsung Galaxy A5 (2016) SM-A510F (17,000-22,000 rubles)

It is surprising that the model is sold in the price range from 17 to 22 thousand rubles. It is difficult to explain what caused such a big difference. In our rating of phones under 20 thousand rubles, the model is on the 5th place. An overview is available.

Specifications:

Cool design and performance, high build quality of the case, support for two SIM cards and camera stabilization. All these are advantages that may give reason to take the model for the flagship. In fact, this is not the case, although the phone is good, it clearly falls short of the flagship.

There are disadvantages: weak screen that is very easy to break. Screen repair will be very expensive - about 7-9 thousand rubles. So we recommend that you immediately stick the film and use the gadget very carefully. Unrepairable is a significant drawback... But if you evaluate the characteristics and assembly, then they are quite consistent with the price. The device is productive and functional, it is worth the money.

Video review:

5th place - Xiaomi Redmi 3 (9-13 thousand rubles)

In some stores, the model can be found at a big discount for 9,000 rubles. But most often the price is 10-13 thousand rubles.

Specifications:

The main thing: the slot for the second slot for the SIM card is combined with the slot for the memory card. Therefore, if 16 GB of memory is not enough for you and you want to increase it with a memory card, then you will have to sacrifice a SIM card slot - keep this in mind.

The big plus is the 4100 mAh battery. First of all, the phone can boast of this, which with active use will last for 1-2 days. It is also reliable (nothing can fall), well-assembled, equipped with a camera that is not bad for its price segment. By the way, it is possible to use 2 SIM cards and a flash drive at the same time, but for this you have to work a little with a file.

Possible disadvantages: very slippery (it tends to swim on any slightly oblique surface), incompletely Russified firmware (there may be hieroglyphs, although this problem can be solved).

In general, this phone is excellent, and it justifies its price 100% - we recommend it.

Inexpensive smartphones with two SIM cards

Below are models that can work with two SIM cards, but at the same time their price does not exceed 5,000 rubles. And yes, buyers speak well of them too.

1st place - LG Leon H324 (4700 rubles)

It is a simple and uncluttered Android smartphone with a 4.5-inch screen with a resolution of 854x480. It has a 5-megapixel camera, good hardware (4 cores, 1.3 GHz, 0.768 GB of RAM) and a decent 1900 mAh battery (quite enough for such characteristics).

The device is reliable, durable, with good characteristics, collects positive reviews, but it also has its drawbacks. First of all, there is no light sensor, there is little memory, and in low light the camera shoots terribly. But the device costs its money, and it is not for nothing that it is in the first place in the rating.

Videooverview:

2nd place - Microsoft Lumia 430 (4200 rubles)

Another decent and inexpensive device worth 4,200 rubles at the beginning of 2017. It supports 2 SIM cards and runs on Windows Phone 8.1 software (unlike previous Android models).

A phone with a 4-inch screen with a resolution of 800 × 480, a 2-megapixel camera, and a simple 2-core 1.2 GHz processor. The amount of RAM is 1 GB, its memory is 8 GB. The battery is only 1500 mAh, but it is enough for a similar phone with low power consumption.

Basically, we have nothing to say about this model. It is reliable, high quality and affordable. Therefore, it is highly popular, collecting good reviews. It lacks any unique characteristics and does not boast high performance. It simply performs its functions - it allows you to call, write, surf the Internet.

Videooverview:

3rd place - HOMTOM HT17 (4300-5000 rubles)

Few known manufacturer HOMTOM can offer a good cheap model with support for two SIM cards.

Its characteristics are standard for its price category: a 1.1 GHz 4-core processor, 1 GB of RAM, 8 GB of its memory. True, there is a good screen with a diagonal of 5.5 inches and a resolution of 720. Well, the cameras here are also quite good - with resolutions of 13 and 5 megapixels.

The model was produced in 2016, supports 4G, has a fingerprint scanner and a good 3000 mAh battery. Also, there are good viewing angles, and the phone "lives" for a very long time in the power saving mode. Perhaps the ideal smartphone for its money, and it is in 3rd place only because of the insufficient number of positive reviews. There are complaints that it does not catch the network well - it is worth checking this, and if this is true, the phone can be returned to the store.

Videooverview:

4th place - Alcatel One Touch Pixi First 4024D (3500 rubles)

Technically, it will not surprise us with anything, however, it costs only 3,500 rubles.

The main thing: a 4-inch display with a resolution of 800x480, a 5-megapixel rear camera (front with a resolution of 2 megapixels), a 4-core processor with a frequency of 1.2 GHz, 512 MB of RAM and 4 GB of internal memory (only 2 GB is available). Yes, you can insert a flash drive here if you want. The battery is weak - only 1450 mAh, but given the low power consumption, its capacity will be enough to work for one day.

There won't be much to say about him. It's cheap, does its job and supports 2 SIM cards. This is the main thing. Yes, there is a bad camera, weak battery, lousy performance, but the price of 3500 rubles nullifies all these disadvantages. In the rating of phones under 5,000 rubles, it is in 10th place, which is also not bad. The rating itself “lies”.

Videooverview:

5th place - Huawei Y3 II (4600-5200 rubles)

Like the previous ones, this is a simple dual-SIM smartphone at a low price. It has a 4.5-inch screen with a resolution of 854x480, a 5-megapixel camera and a simple 4-core 1.3 GHz processor, 1 GB of RAM. Its memory is only 8 GB, but there is a slot for a memory card.

The battery - its capacity is 2100 mAh, which is enough for 2-3 days of active work (low power consumption of components). The device works great as a navigator, does not freeze in the process of work and copes with its tasks.

If in work or everyday life you often have to use different cellular operators, then for convenience you need to choose a smartphone with support for two SIM cards. Today, such models are presented in a huge assortment, so users will definitely not be faced with a lack of choice. However, such a variety is unlikely to please people who do not want to study the parameters and reviews of dozens of devices, trying to choose among them the device that is optimal in terms of price, quality and capabilities. In this case, our rating of the best smartphones with 2 SIM-cards will help to make a competent purchase, in which we will present the highest quality models for today.

The best inexpensive smartphones with two SIM cards (up to 10,000 rubles)

If you use your phone primarily for calls, sending SMS, chatting in instant messengers and social networks, as well as navigation or other simple tasks, then you hardly need a powerful hardware platform, an impressive camera or a high-resolution display. All these add-ons unnecessary for communication with relatives and colleagues only increase the cost of a smartphone, but do not bring any practical benefit. A high-quality smartphone with two SIM cards that can satisfy all your needs can be purchased within 10 thousand rubles.

1.Xiaomi Redmi 4X

In the first place will be the best smartphone in terms of value for money. The Redmi 4X model is one of the best-selling Xiaomi phones. The huge popularity of this device among users is explained by its excellent build, high-quality metal body, bright display with HD resolution and a diagonal of 5 inches, as well as good cameras for a budget device. The smartphone also pleases with a powerful 4100 mAh battery and balanced hardware, represented by the Snapdragon 435 processor and Adreno 505 graphics. RAM and ROM in Redmi 4X are installed 3 and 32 gigabytes. In this case, the permanent memory can be expanded due to microSD cards (installed instead of the second SIM). In general, in terms of parameters, a Xiaomi smartphone is the best device that can be purchased in a price range of up to 10 thousand rubles.

Advantages:

• good "filling";
• high-quality matrix;
• reliable assembly;
• attractive design;
• battery life;
• good cameras;
• infrared port.

Disadvantages:

• no critical remarks were found.

2. Meizu M5c

If you are ready to sacrifice performance for the sake of a great design, then it is better to buy the Meizu M5c. This model is equipped with a 5-inch HD display, simple 8 and 5 megapixel cameras, MT6737 processor, Mali-T720 graphics, as well as 2 GB of RAM and 16 GB of ROM. This cheap smartphone will not cope with demanding games, but the device is just ideal for chatting in instant messengers, watching movies, surfing the Internet and similar simple tasks. In addition, it costs only 8,000 rubles, offering for this price, among other things, a tray for two Nano SIM format and support for all LTE bands used in Russia.

Advantages:

• beautiful and comfortable shell;
• system performance;
• build quality;
• attractive design;
• battery 3000 mAh;
• great screen;
• good conversational speaker.

Disadvantages:

• easily soiled plastic of the case;
• copes poorly with multitasking;
• storage space of the built-in storage.

Best 2 SIM smartphones with powerful battery

Even an excellent system optimization, unfortunately, does not guarantee a long battery life of your smartphone. This is especially true for devices with a large display and powerful hardware, which is regularly used for modern games and watching movies. For this reason, manufacturers install capacious batteries in their devices that can provide an honest day of work even with active use of a smartphone. However, you can buy them not only for those who like to play or watch videos, but also for ordinary users who are tired of putting their phone on charge every evening.

1. ASUS ZenFone 4 Max ZC554KL

The first place in this category was taken by the popular dual-SIM smartphone with 4G from ASUS. The ZenFone 4 Max will set you back around RUB 14,000. For this price, the manufacturer offers a metal body in gold, pink or black, a main 16-megapixel camera, a 5000 mAh battery with support for fast charging, as well as a Snapdragon 425 or 430 processor with an Adreno 308 or 505 graphics chip, respectively. RAM and permanent memory in any modification are installed 2 and 16 gigabytes. In addition, a smartphone with a good battery from ASUS boasts a high-quality 5.5-inch matrix with high brightness and contrast. However, its resolution is only 720x1280 pixels, which is quite small for such a diagonal.

Advantages:

• excellent autonomy;
• small thickness 8.9 mm;
• good hardware platform;
• good main camera;
• high quality protective glass;
• reliable assembly of the device;
• system performance.

Disadvantages:

• little built-in memory;
• low screen resolution.

2. Xiaomi Mi Max 2

If you are looking for a metal smartphone with two SIM cards and a large screen at an affordable cost, then consider the Mi Max 2 from Xiaomi as a candidate for purchase. The Chinese smartphone manufacturer has made a really good device that is suitable for games, movies, internet, communication and other tasks. Mi Max 2 runs Android 7.1 with MIUI 9 shell. The battery in this model boasts an impressive capacity of 5300 mAh, and among other advantages of the device are support for Quick Charge 3.0 fast charging and a USB Type-C port. The latter complies with the 2.0 standard, so you should not count on fast data transfer over the wire. However, for a mobile phone with an average price of 15 thousand rubles, this is forgivable.

The hardware platform of the smartphone is represented by a combination of Snapdragon 625 and Adreno 506, which is popular today. RAM and ROM are 4 and 64 gigabytes, respectively. Such "hardware" allows to make the price of the phone affordable for a wide range of users, and also guarantees good performance even in the most demanding games. Traditionally for the company, this inexpensive but high-quality smartphone is equipped with an infrared port and a fast fingerprint scanner on the back panel. The screen in the reviewed device is 6.44-inch, and its resolution is Full HD. The resulting pixel density cannot be called ideal, but such a decision by the manufacturer is explained by the manufacturer's desire to provide maximum performance and the best autonomy.

Advantages:

• large and high-quality screen;
• excellent hardware platform;
• support for fast charging function;
• infrared port for equipment control;
• high-quality assembled metal case;
• stock of built-in and RAM;
• good main and front cameras (including the price).

Disadvantages:

• no NFC support;
• weak sound in headphones;
• hybrid SD card slot.

3. ZTE Blade A6

In third place, we decided to include in the review, a budget smartphone ZTE Blade A6 with a 5000 mAh battery. The device supports Qualcomm fast charging, but only the second generation. The screen in the reviewed device is 5.2-inch, and its resolution is 720x1280 pixels. For a model for 13 thousand rubles, such a matrix cannot be called the best choice, but with HD resolution, the Snapdragon 435 processor and the Adreno 505 graphics chip are able to demonstrate a fairly high performance for their class in modern games. The 13 (main) and 5 (front) MP cameras installed in the Blade A6 are suitable for undemanding users. However, given the stated price, they cannot be called good. Of the other disadvantages of the smartphone, according to customer reviews, one can note a quiet sound in the headphones, especially when it comes to the complete headset, as well as the proprietary shell.

Advantages:

• high-quality assembly;
• attractive appearance;
• system performance;
• gaming performance;
• fast operation of the fingerprint scanner;
• high-quality matrix;
• support for fast charging.

Disadvantages:

• not everyone will like the MiFavor interface;
• poor quality of cameras;
• the volume in the headphones is not enough.

The best smartphones with two sim cards and a good camera

The times when even for amateur photography it was necessary to purchase a bulky camera are far behind. Today, even an ordinary mobile phone is capable of taking great pictures, suitable for posting not only on social networks, but also in family albums. Moreover, the cameras of many smartphones record videos of a very decent quality, so an ordinary mobile phone can become a tool for maintaining a full-fledged video blog. If you are interested in one of these tasks, then the below models of smartphones will be the perfect option for purchase.

1. Sony Xperia X Performance Dual

The first place in this category went to the Xperia X Performance Dual from the Japanese brand Sony. This smartphone has 2 slots for SIM-cards of the Nano format, one of which is combined with a place for installing microSD with a capacity of up to 200 gigabytes. Most users won't need a separate storage, however, as the Xperia X Performance comes with 64GB of permanent storage. RAM in this unit is 3 gigabytes, which is enough for any application. The same can be said about the powerful 4-core Snapdragon 820 processor, supplemented by the Adreno 530 video chip. Otherwise, the presented smartphone does not disappoint in terms of characteristics: a high-quality 5-inch Full HD matrix, an NFC module, a fast fingerprint scanner and IP68 protection. But what is most impressive about the smartphone is the main camera. Selected for the smartphone, the Sony Exmor RS module boasts f / 2.0 aperture, wide ISO range from 100 to 12800, 22.85 MP resolution and fast autofocus. The front camera is a slightly simplified version of the sensor with excellent light sensitivity and a resolution of 13 MP, which is enough for great selfies even in low light conditions. The only drawbacks of the device are the outdated micro-USB port by modern standards, as well as a battery of only 2700 mAh.

Advantages:

• powerful "filling";
• display with accurate color reproduction;
• high-quality assembly;
• protection of the case according to the IP68 standard;
• high-quality sound in headphones;
• loud stereo speakers.

Disadvantages:

• scratch-resistant back cover;
• strong heating in games;
• average battery capacity.

2. Meizu Pro 6

Meizu has always been able to create reliable and worthwhile smartphones. Users considered devices from the Pro line to be one of the most interesting devices of the Chinese manufacturer. However, the recently released Meizu Pro 7 turned out to be very contradictory: with a combination of interesting "chips" and good design, the device disappointed with its insufficient elaboration and high cost. For this reason, even now, when the price of the latest flagship Meizu has dropped slightly, consumers are more willing to purchase the Pro 6 model, which we decided to choose for our rating.

This smartphone uses a 10-core Helio X25 processor and 4-core Mali-T880 graphics. RAM and internal memory in the device are 4 and 32 GB, respectively. One of the key advantages of Meizu Pro 6 is the touch-mechanical Home button, on which a large number of functions are tied, such as going to the main screen, returning and unlocking the phone using a fingerprint.

Another important advantage of the reviewed mobile phone with a good screen (5.2 inches, Full HD, Super AMOLED) is the Cirrus Logic CS43L36 audio chip. Thanks to the DAC and the competent work of specialists from Meizu, the sound in the Pro 6 is simply amazing. Even more than a year and a half after its release, this device leaves most of its competitors far behind.

A smartphone would be a good choice for amateur photography as well. Installed here, the Sony IMX230 sensor with an aperture of f / 2.2, a resolution of 21 MP and laser autofocus takes excellent pictures even in low light conditions. But the front 5-megapixel camera OmniVision OV5695 is of average quality and makes a lot of noise in the dark. However, this is not even half as disappointing as the lack of NFC in a modern device.

Advantages:

• good juicy screen;
• system performance;
• attractive design;
• high-quality assembly;
• mTouch button;
• infrared port;
• fast charging function;
• slim body;
• USB-C 3.1 standard.

Disadvantages:

• no NFC module;
• battery capacity (2600 mAh);
• there is no possibility of expanding memory;
• the quality of the front camera.

3. Huawei Honor 9

Another excellent smartphone with two SIM cards is offered by the Chinese brand Huawei. In terms of workmanship, the Honor 9 leaves behind most of its competitors. The manufacturer has equipped this device with a bright Full HD matrix with a diagonal of 5.15 inches. The hardware part of the mobile phone is represented by the Kirin 960 processor and the Mali-G71 graphics chip. The RAM and permanent memory in the Huawei Honor 9 smartphone are installed 4 and 64 GB, respectively, and if necessary, the user can expand the built-in storage due to micro-SD cards up to 256 GB. The reviewed model also makes the best in terms of price-quality ratio a smartphone of the TOP with a number of useful features, such as the presence of NFC, infrared port and fast charging function. In addition, the smartphone is great for mobile photography. A dual camera is installed here, consisting of a 12 MP color module and a 20-megapixel b / w sensor, which allows you to take high-quality monochrome shots and expand the dynamic range in ordinary photos.

Advantages:

• high-quality complete bumper;
• high build quality;
• excellent appearance;
• bright design;
• thoughtful user interface;
• powerful hardware;
• infrared port and NFC;
• matrix with good color rendering;
• excellent dual camera.

Disadvantages:

• slippery glass body;
• USB-C 2.0 port.

4. Xiaomi Mi Note 2

Our review ends with an inexpensive but good large-screen smartphone from the Chinese brand Xiaomi. Model Mi Note 2 is equipped with a bright 5.7-inch OLED matrix with Full HD resolution. The hardware part of the reviewed device is perfect for any resource-intensive applications and "heavy" games: Snapdragon 821 processor (2 x 2.35 GHz + 2 x 2 GHz), Adreno 530 graphics chip with a frequency of 653 MHz, 4 gigabytes of LPDDR4 RAM, as well as 64 GB permanent storage.

Which smartphone for 2 SIM cards to buy

In terms of hardware and software, devices with two SIM cards are no different from ordinary smartphones with one card. Therefore, when buying them, you can rely on exactly the same criteria. However, business people who are interested in staying in touch with the other even when talking over one operator should choose a smartphone with two active SIM cards. Such devices are equipped with two radio modules, so that each slot can be serviced separately.

Usually a smartphone with two SIM cards has certain limitations. When you are talking on one SIM-card, the second is busy for those who dial your number. But this can be a very important challenge that must not be missed! If you are afraid to face such a problem, then you need to choose not just a device with two sim cards. Make sure they can run in parallel. Unfortunately, very few such devices have been created. We will talk about almost all of them in today's article.

If you already have a device in your hands, into which a pair of sim cards is inserted, then you may want to check the supported mode of operation. To do this, just call yourself from one number to another. If the call does not go through, then the SIM-cards work in an alternating mode. If it passed, then everything is in order: both SIM-cards work at the same time.

The best inexpensive smartphones with dual sim cards

Manufacturing a device with two radio modules is a rather complicated and expensive task. Therefore, a very small number of companies are now engaged in this business. Most often, their products are very expensive. Fortunately, there are exceptions to the rule, as evidenced by the ASUS ZenFone 2 ZE551ML. Despite the presence of as many as 4 GB of RAM, the device is quite inexpensive. The exact cost will depend on how much onboard storage you need.

We recommend opting for the 16GB version, as you can always use a microSD card if needed. The device is capable of transmitting data via LTE networks. It also has Bluetooth 4.0 wireless modules and, more importantly, Wi-Fi 802.11ac at its disposal.

An interesting feature of the smartphone is the fact that it is powered by an Intel processor. A good graphics accelerator is also here, with it the device is capable of launching any modern games. However, sometimes the graphics settings will decrease. But nothing else was expected from such an inexpensive smartphone.

Overall, this is a fairly powerful device with a good battery. He can only grieve with a large amount of marriage. And we strongly advise against updating to the sixth version of Android, as it has numerous incurable errors here!

A smartphone that combines a bunch of advantages and disadvantages. It has a capacious battery, which ensures long-term autonomous work. Also, the device is capable of boasting good protection from dust and water. But all this led to the fact that the smartphone weighs an unacceptable amount! Also, not everyone will like the fact that such an expensive device has an outdated version of the operating system. However, there are also more recent versions of the device equipped with Android 5.0.

Unlike many other modern smartphones, the Conquest S6 has an event light. It is very convenient to immediately notice if you missed an incoming message or some kind of notification. Under the body of the device, 1 GB of RAM and 8 GB of permanent memory are hidden (but there are other configurations). At the time of the announcement, it was the gold standard. Now this may not seem enough. An interesting feature of the Conquest S6 is the presence of a loop for a carabiner or a lanyard. This suggests that the purchase of a smartphone is recommended for lovers of active recreation.

Dignity

• Waterproof to IP68 standard;
• Long battery life;
• There is a loop for a lace or carabiner;
• There is a gyroscope, compass and a couple of other sensors;

If you need to buy a smartphone with a protected case, then it is quite possible to pay attention to the Torex S18. Unlike some competitors, it doesn't cost astronomical money. Although no one disputes the fact that budget phones are even cheaper. This model differs in its size - the device easily fits into any average pocket. On its front panel there is a 4.3-inch display made using IPS technology and having a resolution of 540 x 960 pixels. With such a diagonal, this is quite a tolerable parameter; it is quite difficult to see individual pixels for the naked eye. And the device can also please with a 13-megapixel camera. Surprisingly, the creators even worked on the front-end. Its 5 megapixel resolution is not enough for shooting masterpieces, but it is quite enough for communication via Skype. The body of this device is protected from water, dust and shock. But it still cannot be called very reliable - at least the touch keys under the display speak about it. But the Torex S18 can still be considered a productive one. It has 2GB of RAM, and a MediaTek quad-core processor can handle any application. A smartphone is not suitable only for modern games, but it is understandable. The device does not disappoint in terms of communication either - the creators have implemented an LTE module into it.

• Many useful sensors are available, including a barometer and a compass;
• Data transmission via 4G networks is possible;
