Micro-SIM and Mini-SIM - how are they different? What is the difference between MicroSDHC memory card and MicroSDXC memory card.

Are you trying to find the right scooter for your child? Would you like to know what is the difference between the Mini Original and Mini Deluxe scooter models?
This guide explains the differences between the Mini Micro Original and Mini Micro Deluxe scooters.

So, what are the differences between Mini Micro Original and Mini Micro Deluxe scooters.

Age suitability

  • The original Mini Micro scooter is suitable for 3-5 years old children
  • The Mini Micro Deluxe scooter is designed for children aged 2 to 5 years

Maximum weight

  • The classic Mini Micro kids scooter has a weight limit of 20 kg
  • The Mini Deluxe scooter has a weight limit of 35 kg

Adjustable steering wheel

  • Classic Mini Micro steering wheel not adjustable in height
  • The handlebars of the Mini Micro Deluxe scooter are adjustable (48 cm to 68 cm)

Steering rack

  • The classic Mini Micro has an aluminum steering rack
  • Mini Micro Deluxe has an anodized finish that protects the scooter's handlebars from corrosion

Deka

  • The classic Mini Micro has a simple grooved fiberglass (GFK) deck
  • Mini Micro Deluxe has a special silicone coating on the deck in the form of the model name and logo, which not only improves the grip of the scooter with the sole, giving children a safer footing when riding, but also unique, which ensures that you have a genuine Micro scooter.

Similarities between Mini Micro Classic and Mini Micro Deluxe scooters:

  • the handlebars on both models can be completely removed from the platform, which is quick and easy
  • tilt control. This means that the child must tilt the torso in the direction in which he wants to turn. This control method helps to improve the child's coordination and fine motor skills.
  • quality rear brakes. The brake on the Mini Micro is easy to use and durable
  • lightweight frames. The Mini kids' scooters have a lightweight frame, which allows the child to operate the scooter effortlessly. For example, a child can easily pick up the scooter and move it if there is a curb in its path.
  • the special structure of the soundboard protects the baby's ankles from bruises
  • three wheels, which are durable and leave no marks, allow the scooter to be used both outdoors and indoors. The scooter on three wheels is stable, the child does not need to balance - you can easily get on and off the scooter
  • Spare parts. This is what really takes Micro scooters to another level. Each part is replaceable. Our service can always help with the availability and replacement of spare parts. You can also replace spare parts yourself, following the instructions.


We hope this guide helped you understand the difference between Mini Micro Classic and Mini Micro Deluxe. If you have any questions, please write them in the comments below. We will be happy to answer you.

It should be noted that SIM cards are generally used by all mobile operators to identify subscribers... Thanks to this, any subscriber can easily and quickly change cell phones, tablets, without changing his phone number, but simply by moving his SIM card to another phone. Now there are several form factors of "sim cards": regular and micro-SIM.

All SIM cards include microprocessor with software and IMSI data(international mobile subscriber identifier), serial number, temporary information about the network and services available to the user, as well as some other data (for example, the phone book), access to which can be protected by a system of PIN codes.

Surprisingly, the SIM cards we are used to are actually called mini-SIMs. A full-size SIM-card is similar in format to a bank card - their dimensions are exactly the same: 85.6x53.98x0.76 mm . All familiar "SIM cards" that we use in mobile phones, mini-SIM, "break out" of such a card. Pay attention to the kit that you purchase upon connection. The size of a standard SIM card of mobile operators is 25x15x0.76 mm.

Micro-SIM is the newest version of the subscriber module, differing from all previous sizes - 15x12x0.76 mm... For the first time, it was talked about back in 1998, but the final version of the form factor was agreed only at the end of 2003. The main purpose of creating a micro-SIM was called the possibility of its use in miniature devices for which ordinary SIM cards are too large. True, what kind of devices they could be, no one specified. Probably some kind of spy stuff.

The launch of mass production of micro-SIM was organized at the suggestion of Apple. All of her new devices could only work with miniature SIM cards.

Externally, micro-SIM and regular SIM differ only in size. Basically, to use a regular SIM card in an iPad or iPhone 4G, you just need to carefully cut it to the size of a micro-SIM... It will work just as well as a factory one, and this straightforward "file-up" method is suggested as the easiest solution. Now almost all operators in the world and in Russia change standard cards to micro-SIM for free... To do this, just go to the service office and write an application.

Meanwhile, not everything is so simple. Despite the complete identity of the chips themselves, the micro-SIM specification provides for a number of new functions that SIM cards of other formats do not have. Primarily, we are talking about supporting the simultaneous access to the card of several applications through virtual channels... This means that data over the operator's network will be transmitted in parallel streams, and not sequential, as was the case before.

New specifications describe enhanced security, in particular, the system of mutual authentication of the card and the cell to which it connects. This allows you to prevent IP spoofing - a fairly common method of hacker attacks, which consists in intercepting a subscriber's IP address and then using it either to enter secure networks or to substitute a real IP address in order to obtain the necessary data on the attacker's device.

The emergence of hierarchical system of PIN-codes with universal PIN-code, application code, and local code. By analogy with computer operating systems, the universal code grants full system administrator rights, and all others - limited rights to perform some specific actions. Obviously, such a measure should prevent not so much accidental damage to the data stored on the card (and on the connected device), as malicious attacks aimed at gaining control over the terminal, including using unauthorized software.

And, finally, the fourth new function inherent in the micro-SIM specifications is support for an expanded phone book of increased volume, which allows storing second names of subscribers, groups, and e-mail addresses on a SIM card.

How to make a micro-SIM from a regular SIM card

id = "sub0">

Manufacturing technology is very simple. To do this, we need sharp scissors, a sharpened pencil, a ruler with millimeter cutoffs. It should be borne in mind that all work must be carried out extremely carefully and carefully.

Stage 1. We measure the length and width of a standard SIM card. "Sims" in our phones have the following dimensions, mm: 25 x 15 x 0.76. We are required to finish them up to the micro Sim standard: 15 x 12 x 0.76. It is not worth focusing on the thickness of attention - it is the same for both standards of SIM cards.

Stage 2. We mark the cutting lines. Draw a 15 x 12 mm rectangle around the metal chip and mark the lines with a pencil.
It is worth noting here that some SIM cards have an oversized chip - in this case, you need to cut it into metal, however, the chances are then that the SIM will survive this approximately 50/50.

Stage 3... Cut with scissors. Slowly cut off the excess plastic on the sides. Women's nail scissors are ideal for the operation - they are quite miniature, and at the same time, very powerful. After cutting, you need to compare the size of the received SIM card with the SIM card slot of your iPad or iPhone 4. If the SIM card is larger, carefully cut it further with scissors.

After that, your micro-SIM is ready.

For our part, we would like to note once again that subscribers of MTS, Beeline and MegaFon can change their regular SIM-card for micro-SIM completely free of charge at customer service centers. With the rest of the operators, the situation is somewhat more complicated, and here you can use a handicraft method of manufacturing micro-SIM

Minisim- this is an ordinary and familiar SIM card of a standard size, which is usually called a "SIM card", without the "mini" prefix. The most widespread format of SIM cards, but today they are more and more difficult to find in new smartphones.
The size of a regular, standard SIM card or mini-sim - 25 X 15mm

Microsim- this is the same SIM card as the mini-sim, but unlike it, the micro-sim has a smaller size of 15 X 12mm. As a rule, SIM cards are already sold with the ability to make a micro-SIM out of an ordinary SIM card by simply squeezing the micro-SIM out of the plastic frame of the card.

A universal or multisim card looks like this (you can see the boundaries along which you need to squeeze out the desired size of a SIM card):

What is a Nano SIM card?

Nanosim Is the newest SIM card format, and today it is the smallest SIM card size for smartphones and tablets. The nano-sim does not have plastic around the chip, as can be seen in the mini-sim and micro-sim. The size of a nano-SIM card is half the size of a standard SIM card and is 12.3 X 8.8 millimeters, which is practically the size of the chip itself, but still has a small border.

Micro-sim and nano-sim: is the difference in the size of the plastic or in the chip?

Based on the above characteristics of SIM cards, you can notice a significant reduction in plastic, directly at the edges of the SIM card chip. SIM card sizes are the key and main sign of what a SIM card is called. This size affects only the plastic, there are no changes in the chip itself and cannot be. You can use a regular SIM card (mini-SIM), and if you update your smartphone to a newer model that requires a micro-SIM, you can change it to the desired size at any time, be it micro-sim or nano-sim.

How to cut a SIM card for a nano-SIM?

There are several ways to make a nano-sim out of a micro-sim:

The first way- this will contact a specialized store or a communication salon of any operator, and in a couple of minutes they will make the required SIM card size for you. The cost of this service, as a rule, does not exceed the cost of the starter package / SIM card itself, or is free at all. This service will definitely be free if you buy a starter package and immediately warn about which SIM card you need, in which case the operator's representative must give you the required size of the SIM card.

Second way- this is to cut off the SIM card yourself for the nano-sim. Be prepared to use a ruler, scissors or a sharp utility knife and possibly sandpaper. Attention! This method is less preferable, since there is a risk of touching one of the 6 contacts of the chip of your SIM card, because of which, you will need to restore the SIM card by contacting the operator.

So, if you decide to cut the SIM card yourself, then let's go directly to the cropping:


Remember! Having cut off a SIM card, for example, to the size of a nano-SIM, they can still differ in thickness, since the thickness of a nano-SIM card is 0.67mm, while a mini-SIM and a micro-SIM can be: 0.76-0.84mm.

How to insert a nano-sim into a micro-sim?

Changing the size back from nano-sim to micro-sim or mini-sim is much more difficult, because you need a holder / adapter or "holder" for the sim card. If you have one, then you will not have any difficulties with resizing, just insert the chip into the required adapter and place it in your smartphone or tablet.

The image shows how the adapter for nano-sim and micro-sim should look like, as you can see there is nothing complicated about it, you just need to buy a holder or keep it, after buying the sim card itself, as a rule, multisim cards are sold.

Manufacturers of smartphones and tablets strive to reduce the size and weight of their devices as much as possible in order to make them more stylish, convenient and powerful, so there is no place for unnecessary and completely unnecessary plastic from SIM cards in the new models. Instead, you can reduce the size of the gadget itself or enhance it with other useful functionality: processor, memory, etc.

It is the size of the tray or slot for a SIM card that determines the required size of the chip, it will depend on which SIM card you need. As a rule, for smartphones that allow you to use 2 or more SIM cards at the same time, you need to have a microSIM or nanoSIM.

Also, it is worth mentioning that recently, manufacturers have begun to increasingly use technology for SIM cards and memory cards, however, this is not always convenient, remember this when.

Experienced consultants of telecom stores still remember the time when buyers were puzzled by the fact that there are non-standard SIM sizes. Now the presence of several types of SIM cards is a common thing. Manufacturers are giving preference to ever smaller cards, because this saves space inside the device case. Sims are of a standard size, bulky by modern standards, and look like they will "sink into oblivion."

In this article we will tell you about all types of SIM and teach you how to make a small one out of a large card.

In terms of size, SIM cards are classified into 3 types:

Mini-SIM

Mini-SIM- this is the "scientific" name for a standard SIM card. Its dimensions are 25 × 15 millimeters.

If the phone was released before 2011 (inclusive), you can be sure that it is inserted exactly Mini-SIM... For modern smartphones, such a map is too large, but this does not mean at all that Mini-SIM- anachronism. Standard SIM cards are used in simple "dialers", in phones with large buttons for the elderly, in protected phones for fishing enthusiasts and factory workers. The listed devices cannot boast of an abundance of functions, so there is a lot of space inside their cases - in some models, manufacturers allow you to install even 3-4 Mini-SIM.

Micro-SIM

First card Micro-SIM began to be used by Apple - in devices iPhone 4. Dimensions Micro-SIM- 15 × 12 millimeters.

Nowadays, the vast majority of smartphones are installed precisely Micro-SIM... Apple's "baton" was taken over by Nokia, which equipped its Lumia devices with slots for Micro followed by HTC, Samsung, BlackBerry.

Nano-SIM

Nano-SIM- the newest and smallest phone card. Its dimensions are only 12 × 5 millimeters. Visually, the card is a chip with a minimum of plastic edging.

The innovator was again Apple. Exactly Nano-SIM users had to insert into iPhone 5th modification. Later, devices with Nano-SIM-slots began to be produced by other well-known manufacturers, for example, Samsung and Meizu.

The following illustration will help you understand the differences between the three types of SIM cards from each other:

How to change the size of the SIM card for the phone?

The most obvious way to change the size of a sim card is replace it in the operator's cabin... This procedure is completely free, it only takes a couple of minutes, the phone number does not change afterwards. However, this method still has a number of disadvantages:

  • The new SIM card will not have numbers stored in the old memory. Of course a similar problem easy to solve: in the article "How to transfer contacts from iPhone to computer" we talk about several ways to export phone numbers at once. But, alas, many users consider their time too valuable to be spent on mastering third-party software and methods of creating backups.
  • Have the right to replace the SIM card in the office only its designer and only according to the passport... If the card was presented to the user, for example, by his parents, he himself will not be able to replace it. Sometimes this becomes a real problem.

If the consultant changes the SIM card to a person who is not its designer, this is a fraud! For such an operation, the consultant will at least be deprived of the bonus, and at the most, he will be dismissed in disgrace. Therefore, it is pointless to demand “make an exception”; no one wants to be unemployed with an impartial wording in a work book.

There are several ways to change the dimensions of a SIM card without having to replace it. For example, a user can purchase adapter(he is - adapter). The adapters look like this:

It is better to order adapters for SIM on Chinese sites - there they are a mere trifle. For example, a set of adapters from Noosy together with a needle for iPhone will cost only 17 rubles. When buying in the salon, the user may be required to pay up to 250 rubles - the difference is more than noticeable!

The set, as a rule, includes adapters of 3 types: Nano-SIM to SIM, Micro-SIM to SIM and Nano-SIM to Micro-SIM... Since SIM cards of reduced size continue to be associated with Apple, manufacturers do not forget to put needles in the kits to remove the SIM card slot. Using adapters is easy: a small SIM card is inserted into a suitable adapter, then the adapter itself with a card inside is placed in the slot of the mobile device.

Adapters help when you need to increase the size of the SIM card, but what about the user if the card, on the contrary, needs to be reduced? The owner of the gadget should think about the fact that such a need may arise even at the stage of buying a SIM card - and insist on issuing him a so-called Combi-SIM. Combi-SIM Is a standard size card, from which you can make a micro SIM card in a split second.

Inside a SIM card, standard in size, Micro-Sim is already cut along the contour, so it is quite easy for the user to press down with his finger and break off a piece of plastic.

You don't need to rush to throw away the frame- she is still capable of doing good service. If it becomes necessary to re-insert the card into the slot under Mini-SIM, the frame can be used as an adapter.

Usage Combi-SIM- one of the ways to change the size of the SIM card downward. Cards Combi provided to mobile users is free- of course, if they are available at the operator's office.

If the user already owns a standard SIM card and wants to turn it into Micro without losing contacts, he has no other choice but to cut the SIM card. Trimming, as a rule, is carried out using a special device called stapler for sim(it is - cutter for sim, it is - Sim Cutter).

Make from a standard card Micro-SIM in the presence of such a stapler - a second procedure. However, expect the sales office or workshop to carry out this procedure. is free, not worth it. The salon employees will demand 149 rubles for trimming and even knock out a check for the provision of a paid service. Repair shops will also ask for money - or they will even send the user to deal with the operator.

Cutting a SIM card is associated with some risk - if the person performing the procedure hurries up or is inattentive, he will damage the chip, and, as a result, the SIM card will not function. Hence the high cost of the pruning service - no one wants to risk it for nothing.

How to cut a SIM card with your own hands?

Not all mobile shops have staplers for SIM - some consultants continue to cut cards with their own hands and with ordinary scissors. Perhaps the reader will be surprised by the fact that no one teaches this to consultants. They hone this skill on their own, and many successfully cut off the SIM card. the first time.

No wonder - in reality, the procedure is extremely primitive! Usually the main difficulty is finding a template. As a rule, consultants' desk is littered with sim cards of various sizes, working and having served their time - they use them as samples. An ordinary user can only dream of such an abundance - however, if he nevertheless managed to borrow a SIM card of the required size for the role of a template, he can safely try cropping with his own hands. If not, he should resort to using a printer and template print out(here is a suitable link).

To trim a SIM card, you do not need markers, rulers and pencils - if you follow these instructions:

  • Take the large SIM in your hand with the chip facing up.
  • Place the sample card on top so that it completely covers the chip, press it firmly with your thumb and do not let go. If desired, the template can be attached to the large SIM using double-sided tape, but experts do not recommend doing this - you can damage the chip.
  • Trim the sides carefully. Try not to have enough too much, otherwise the SIM card in the slot will "dangle" and the signal will be lost.
  • Crop the card to the template across... Here you can act less scrupulously; the main thing is not to touch the chip.
  • Remove the corner and round off the edges a little - otherwise the SIM card will not fit into the slot.

Next, put the template aside and try to install the cut-off card in the phone to test its functionality. If the SIM card does not fit into the slot, carefully trim the plastic and try again. If the card slot is just the right size and can be read by the phone, celebrate - you just cut the SIM card with your own hands!

note that not any card can be "cut" to the desired size. Easiest to redo Mini-SIM v Micro-SIM - such cropping should not cause any difficulties for the user at all. Trim under Nano-SIM always harder; plastic around the chip on the card Nano almost not, so the risk of snagging the chip with the scissor blades is quite high.

In everyday life, there are still SIM cards of the old model - with large chips:

Cutting such SIMs is a real nightmare! With a bit of luck, you can make from such a card Micro-SIM, but turn it into Nano will definitely fail.

Conclusion

The fact that smartphone manufacturers have begun to release gadgets that support various types of SIM cards, the sellers of the salons have enriched themselves decently. Of course, not all paid services go through the cashier - in many cases, the money for pruning goes to consultants in the pockets. Cutting SIM cards for sellers is a "bread business", which means that free the help of consultants is nothing to count on.

Therefore, the user who does not want to "feed" the employees of the salons, it is better to master the skills of pruning himself. This procedure is quite simple and does not require "surgical precision".

Mini USB is already losing its position in the market, and it is being replaced by its analog - Micro USB. The key feature of Micro USB is its compact form. At the same time, Micro USB is capable of providing no less speed of data transfer from one media to another. Unlike Mini USB, the new version takes up much less space on the PCB (about half as much). It is believed that it is this parameter that is fundamental in the design of small gadgets, such as mobile phones, digital cameras, PDAs, players, etc.

The main differences between Micro USB and Mini USB

Micro USB has a compact type of plug, made on the basis of USB 2.0. This is the kind of improved USB that has been around since 2011. It is he who is used to charge and transfer data for each new mobile device. This is primarily due to the fact that modern manufacturers of gadgets and other small devices have come to the conclusion that a huge number of very different connectors for charging and data transfer are impractical. Thus, it turns out that every new device, be it a phone, tablet or something else, has a standard connector - Micro USB.

As mentioned above - Micro USB differs from its predecessor primarily in its small size. In addition, it is several times stronger than the previous USB version. This is because it is coated with stainless steel and also supports the USB On-the-Go specification. The peculiarity of this specification is that it provides data exchange between two end devices without any additional equipment (computer, laptop, etc.).

The Micro USB connector itself has three types of plug, these are: Micro A, Micro AB and Micro B. The difference between them, as you might guess, lies in the size of the plug, plugs and sockets. This is where the main differences end. The Micro USB cable itself has four conductors. Two of them play the role of transmission, data exchange, and the other two - for power supply, with a voltage of up to 5 volts (that is, for charging the device). As for the visual component, Micro USB on one side has a Micro A, Micro AB or Micro B plug, and on the other end a regular USB input for connecting to a charger, personal computer, etc.
