If Android does not connect to the Internet via the mobile network, then the cause of the problem should be looked for in the system settings. In rare cases, the mobile Internet does not work due to failures on the side of the telecom operator; usually, the user can fix the error on his own.
This article is suitable for all brands that produce phones on Android 10/9/8/7: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.
Attention! You can ask your question to a specialist at the end of the article.
Why doesn't mobile internet work on Android?
The first thing you need to do if mobile Internet does not turn on on Android is to make sure that data transfer is enabled in the settings.
- Open settings, go to “Connections” or “Network connections”.
- Go to the "Data Usage" menu.
- Turn on mobile traffic.
You can also enable mobile Internet on Android using the quick menu. Swipe down with two fingers from the top edge of the screen and a full menu will open with buttons for quickly enabling smartphone functions.
Increase The next step is to check your personal account balance. If your phone has two SIM cards, you need to look in the settings to see which one is used to connect to the mobile Internet, and make sure that the appropriate service package is connected to it.
Another reason why the mobile Internet does not work may be incorrect registration of the phone on the network. To fix the problem, just reboot the device. If this does not help, then check the APN point data by comparing it with information from the operator’s official website. Typically, APN data comes in a configuration message when a SIM card is installed for the first time, but it happens that the user does not save them, or they get lost while using the system.
- Go to the operator’s website - MTS, Tele2, Beeline, Megafon or your regional network.
- Find Internet settings for Android in the help section.
- Open your phone settings. You need the "Mobile networks" section.
- Go to the “Access Points” subsection.
- Change the current point or create a new one using data from the operator’s website.
- Reboot your device.
Manually setting up APN also helps when the Internet does not work in some applications. If this does not help, we can advise you to reset the network settings - the latest versions of Android have such a function.
Increase Another possible reason for the complete lack of mobile Internet is the lack of network coverage. If the “LTE/4G” mode is selected in the Android settings, and the device is located in the coverage area of only the 3G network, then you will not be able to access the Internet. What to do in this situation:
- Open settings, go to the "Connections" section.
- Go to mobile network settings.
- Open "Network Mode" and set it to automatically switch between LTE, 3G and 2G.
Increase If the Internet still does not work in this mode, select a specific value - 3G or 2G. If you are in an area where the operator has no coverage at all, then no change in mode will help. This often happens on the road between cities - not only the Internet stops working, but also calls from SMS.
There is a small chance that problems with connecting to the Internet are related to maintenance work or a failure on the operator’s side. To rule out this possibility, call your provider and find out why your mobile Internet is not working.
Automatic activation of mobile Internet
Another problem with mobile Internet is automatic connection and debiting of money or traffic depending on the tariff. This usually happens because some application requires and uses it without your knowledge. It is very easy to calculate:
- Open the Connections section in Settings.
- Go to the Data Usage menu.
- See which app spent the most traffic.
To prevent traffic from being wasted without your knowledge, turn off your mobile Internet. This can be done in the same “Data Usage” section or in the Android quick settings curtain.
Increase You should also check your Play Market settings. If they enable automatic updating of applications with any connection, then the phone will waste mobile data without asking permission.
Everyone should know what to do if Android won't start. All the methods proposed below do not require additional technical knowledge and cannot harm the operating system or the device itself.
The Android operating system is not only the most popular in the world, but also very simple, convenient and reliable. Nevertheless, any modern device sooner or later fails or begins to work not quite correctly. Such an unfortunate incident is upsetting and can seriously damage your nerves. There are times when the problem is serious and only a specialist can help. But before you go to the service center, you should try a few simple tricks that can completely revive your smartphone.
Battery or charger
This may sound trivial, but more than half of the problems with turning on Android are related to the battery or charger. This is not about the fact that you simply forgot to charge your phone, but about more global reasons.
With prolonged and active use of a smartphone, its battery gradually wears out. There comes a time when it is discharged to such an extent that an ordinary network adapter can no longer help it.
If the phone model is old and collapsible, remove the battery and use the “frog” device. This is a charger that provides a more powerful charge and can save your phone for a while.
Photo: Frog for charging batteries
Owners of one-piece and non-separable models should not experiment at home. If you suspect that the battery may have failed, contact a service center to have it replaced.
The charging AC adapter may also be causing the problem. New chargers may not be original or may not be compatible with this smartphone. This means that the battery does not receive energy during charging, and the android simply cannot start. In old chargers, contacts come off, wires break, etc. Therefore, it makes sense to try charging the phone from a different adapter.
Hardware problems (phone freezes)
It may happen that the phone is not turned off at all, but is “stuck” with the screen turned off. It’s worth figuring out what to do if Android doesn’t start due to freezing.
All procedures will be aimed at maximum activation and restart of the device.
If the phone has a removable cover, remove the battery for a couple of minutes, then replace it and turn on the device. Such a simple manipulation often gives good results and returns the smartphone to normal operation.
With more modern models the situation is a little different, but there is nothing complicated here either.
If, after a standard single press of the power off or lock button, the phone does not turn on, hold down this button for 10-15 seconds. After this, the screen may light up and the phone will continue to work.
The second way to reboot is the so-called “forced reboot”. To do this, you need to find the reset button and carefully press it with a needle, paper clip or toothpick. In all models it is located in different places, but it looks almost the same. If you can’t find the reset button, open the instructions for your phone.
Photo: Reset button on the phone 
Photo: Reset button on a Sony smartphone There is another simple method that can “stir up” your phone. Connect it to your computer via USB. By detecting a new connected device or power source, the smartphone can wake up from its sleep mode.
Software problems
If none of the above methods help, the last chance to turn on the phone yourself will be a complete reset (in technical circles it is called).
There are also several methods and options here.
First, let's consider a situation where the phone still turns on, but does not work correctly and the android constantly hangs.
When you return to factory settings, absolutely all information will be deleted and the phone will become just like new. Therefore, if possible, be sure to back up all data. New models in their menu already have such functions as “data backup”, “backups”, and then full data recovery. Information can be copied to any existing account, Google Drive or to the cloud.
Photo: Phone backup It is also possible to copy all data to a PC or laptop using a USB cable or, for example, a program Share it (Download). It is worth remembering that contacts from the phone book will be saved in one of the folders as a .vcf file.
To reset the settings, go to “Settings”, select “Privacy” (if Android version is 2.2 or lower), and then “Reset settings”. In the latest versions, go to “Settings”, select “Backup and reset” or “Backup and reset”, then click on “Reset”, “Reset settings”, “Reset Tablet PC” or “Master reset”.

Photo: Restoring and resetting your phone When the phone is turned off and it is not possible to turn it on, you must simultaneously press the volume up button and the power button (on some models the volume button, the Home button and the power button). The Recovery technical menu should appear on the screen. You need to select the line wipe data/factory reset (down-up control is carried out using the volume key). Then click on Yes, delete all user data.
Do not forget that for a full rollback to factory settings, you need to clear the entire cache and SD card. To do this, you can go to “settings”, “memory”, “clear SD” or clear it immediately upon reset by clicking on wipe cache partition.
Photo: Recovery menu Important nuances of resetting settings
There are several very simple but important rules that must be followed. For example, during all operations with a smartphone, it must always be connected to charging. Then the phone will not turn off at the most important moment, ruining the entire settings process.
If you plan to reset the settings to factory settings in advance, you need to “overclock” the device’s battery. To do this, first discharge it until it turns off, and then fully charge it. This will ensure that the battery.sys file works correctly.
Since all phones are very different in interface and Android firmware, some users experience certain difficulties during the procedure. Don’t worry, be calm and read every menu name very carefully. If the smartphone model is very new or rare, it is better to study the instructions for it or go to the official website.
Problems after factory reset
Unfortunately, it is quite possible that the Android will not turn on after resetting the settings. You should again press the familiar volume up, power off and Home buttons and hold for 10 seconds. The Recovery mode menu will appear, select the “wipe” item, confirm your decision by pressing the Home button.
In a collapsible phone, remove the battery; under it there is a factory reset button. After pressing it, the settings will be reset again and the phone will turn on.
If the advice does not help, be sure to contact a service center to reflash the software.
conclusions
The tips listed are safe and quite effective. In most cases, with their help you can return the smartphone to normal and correct operation. You don’t need to rack your brain for a long time about what to do if your Android doesn’t start for one reason. In the event that home diagnostics do not give a positive result, you need to contact professionals. The cause of the failure may be serious, for example, completely faulty software, problems with the matrix, or other internal damage.

A modern person is a user of a powerful and productive touch phone. Calls, SMS, searching for information on the World Wide Web, navigation, photo and video shooting, games, reading books - in any of these cases you need a mobile gadget that will instantly respond to the task.
However, it is worth considering that a modern smartphone is a complex and often capricious technical device that can fail at any time.
Before you rush headlong into a mobile device repair shop, you should figure out what caused the breakdown. After all, very often the user himself is able to revive his phone without resorting to the help of a specialist.
In our article, we will analyze in detail why the phone does not turn on, and we will also tell you how to restart your Android mobile device.
Dead battery
The most common reason why an Android phone refuses to turn on is a depleted battery. A common reason why an Android phone won't turn on is a completely discharged battery. The solution here is simple - connect your smartphone to the charger. Please note that if the battery is empty, the phone may take a few minutes to start charging. In addition, the charger itself may not have enough power to fill the battery capacity.
Solution: Frog or Power-bank
If the design of the phone allows, you can remove the battery and install it in a special “frog” charger. A device with a non-removable battery is connected to a power bank.
A suddenly dead battery is a problem that even the owner of a recently purchased mobile device may encounter. In 9 cases out of 10, the problem here is related to improper charging of the gadget. If you want your mobile phone to last as long as possible, read our recommendations in the article How to charge your phone correctly
Faulty charger
What should you do if your phone doesn’t turn on even when it’s charging? Here the problem may lie in the charger itself, namely in its breakdown or damage.
Solution: Second charger
To check whether the charger is in working condition, connect the mobile phone to another charger. If charging has started, you can safely throw away the first charger - it is definitely broken.
Battery fault
On average, the battery in phones is designed to last 2.5 years. If your phone was purchased more than 3 years ago, the battery life may have expired.
Solution: Replace the battery
With a removable battery, everything is simple - go to the nearest mobile electronics store and buy a new battery. But with a non-removable battery you will have to go to a service center.
Problems with charging contacts
Another common reason why the phone does not turn on is broken contacts, which means that even a working battery will not accumulate charge.
Solution: Diagnose and fix contacts
Check the contacts that connect to the battery - they may have moved a little. In this case, take thin tweezers and bend the contact antennae slightly. If you have a special screwdriver for electricians, its indicator will show whether there is voltage in the charger connector. Although in an amicable way, it is better to contact a professional technician with this problem.
Influence of external temperature
Winter and summer become a real test for any touch phone. The fact is that mobile devices do not tolerate high and low temperatures. For example, if you charge your smartphone to 100% and then ride with it on a hot and stuffy bus around the city, you will find that the battery has drained to almost zero.
Solution: Warm or cool the phone
Never charge an overheated or hypothermic phone. First you need to wait until the temperature of the mobile phone is balanced, and only then put it on charge.
Power button failure
A broken start key is also the reason why the phone stopped turning on. Between the button itself and the contact there is a thin rubber or silicone membrane. Due to constant pressure, it eventually wears out and bursts. This can also happen after the smartphone falls onto a hard surface.
Solution: Repair
Fault at the memory card level
The phone may refuse to turn on due to the SD card, especially if it was taken by hand or at an unreliable retail outlet. In this case, there is a high probability that there is a virus on the card that prevents the phone from turning on. On the other hand, a functioning but overcrowded card can cause problems for the user.
Solution: Delete or format
It is better to throw away a defective card immediately, regardless of what is on it. And a card that is packed to capacity should be formatted.
Sometimes users download updates for the operating system from unreliable sources. Such actions can lead to the fact that the mobile device turns into a useless piece of metal.
Solution: Reset to factory settings
The most obvious way to deal with incorrect firmware is to roll back the phone to its original factory settings. You can do this in three ways:
- Through the gadget menu;
- Using service commands;
- In the Recovery menu.
Method 1
- Go to your phone settings
- Click on the "Backup and Reset" section.
- Select “Reset settings”.
- Click on the button at the bottom of the screen.
After a few seconds, the system will roll back its settings and then reboot the smartphone.
Method 2
Service commands are a specific code that must be typed on the smartphone keyboard. Here are the three main combinations:
- *2767*3855#
- *#*#7378423#*#*
- *#*#7780#*#
Method 3
To enter Recovery Mode, follow these steps:
- Turn off your phone.
- Hold down the Power and Volume keys.
- Select the wipe data/factory reset command from the list of options.
- Click Yes.
- Wait for the reset to complete and click Reboot System.
If you want to know thoroughly what is happening inside your mobile device, you can use special free applications. You can read about how to use such utilities in our article Smartphone diagnostics.
Excessive applet updates
Almost all applications installed on the phone, especially those whose work is connected to the Internet, constantly download and install large update packages. Such updates very often overload the phone.
Solution: Uninstall updates
A broken gadget screen is an obvious reason why the phone won’t turn on if there are no problems with the firmware and updates. As a rule, the display does not fail immediately. Pay attention to the moments that precede this:
- From time to time, stripes appear and disappear on the screen;
- The brightness sharply decreases and increases, within a few seconds the screen flickers and is restored again;
- The screen on the phone could suddenly show “strips” or start flickering during operation.
Solution: service repair
If you encounter such troubles, either the display itself is broken on the phone, or the causes of the problems lie in the cable that connects the screen to the board. Of course, you can try to carry out the repair yourself, but without certain technical knowledge, this can lead to complete breakdown of the phone.
Conclusion
Now you know what to do if your phone doesn't turn on. We will also give a few recommendations that will help extend the life of your gadget:
- Do not repair serious damage with your own hands
- Try not to drop your phone.
- Do not install applications from unverified and unreliable sources
Why the Internet does not work on the phone is a question that most users have encountered at least once. The situation is unpleasant, but in most cases it can be solved. In our article we will tell you in detail whether this problem can be fixed and how it can be done, as well as ways to configure data transfer on your smartphone.
#1 The gigabyte package has run out
On some tariffs, access to the network is limited if the user has used up the prepaid traffic package. Therefore, before asking why it doesn’t work, you will need to read the terms of the tariff plan or seek advice from the operator to find out how to connect an additional package if the amount of traffic has really come to an end.
#2 Ran out of money
A common reason why the Internet does not work is balance problems. Although bundled plans are very popular, there are still users who pay for every megabyte they use. The operator turns off traffic when the balance is zero or negative, until the balance is replenished.
#3 Network lost
On some phones, the communication module does not work very stably, so the signal sometimes “falls off”, and along with it the Internet. The problem of no traffic can be fixed by rebooting the phone. If this does not help, then you can try installing updates or even reinstalling the operating system.
#4 “Data transfer” function disabled
Another common reason why mobile Internet does not work on a phone is that the “Data transfer” function is disabled. It’s not difficult to enable it on Android:
- Open "Settings".
- Select “Network and Internet” from the list.
- Check that the slider next to “Airplane Mode” is gray (it doesn’t work).
- Click “Data Transfer” and check if the slider is moved to the “On” position. If the phone is dual-SIM, then the slider is separate for each SIM.
If your Internet does not work on your iPhone, then the problem can be solved in a similar way. In “Settings” you need to select “Cellular” and make sure that “Cellular Data” and the network (LTE/3G/2G) are turned on.
Also, when looking for an answer to the question of why the Internet does not work on your phone, it is worth trying to remember whether you yourself turned off data transmission from your operator.
After all, some operators allow you to block traffic in order to avoid unplanned expenses, but after that it is not easy to access the global network. In such a situation, you will need to contact support or change the tariff settings yourself through your “Personal Account”.
#5 Poor coverage
If a user finds himself in a new place and his phone’s Internet stops working, then it makes sense to look for a signal somewhere nearby. Why is this happening? - So far, no cellular operator can provide ideal coverage, so even in large cities there are “no network” zones.
#6 Wrong choice in “Network type”
In phones, you can choose which type of network will work as a priority: 2G, 3G, 4G(LTE) - they differ in the highest possible speeds. There are also often combined options: 2G/3G, 3G/LTE or even 2G/3G/LTE. In order not to wonder why there is no traffic, you should consider several factors when setting up:
- If the user moves around the city a lot, then he should choose not the fastest type, but the one that has greater coverage. For example, in the city 4G is present only in a few zones. If in such a situation you choose 3G/LTE instead of 3G, then most of the time the phone will check the network for the presence of LTE instead of quietly downloading traffic on the slower 3G. As a result, there are numerous questions from users about why the Internet does not work on the smartphone, although there is a network.
- Combined settings are good if the user's phone doesn't move much, meaning 3G/4G is better than just 3G or 4G.
To choose which type of network will work as a priority, you need to open “Network and Internet” in the phone settings and select “Mobile network”. Then set the settings in the menu that opens.
#7 The settings have gone wrong or this is the first connection to the operator’s Internet
Often, when dealing with the question of why the Internet does not work on an iPhone or Android, the user finds out that his access point settings are wrong/missing. However, this is easy to fix.
The easiest way is to call your mobile operator's support service and ask them to send you automatic settings. The user only needs to click “Save” in the pop-up window, and the data transfer will start working. However, due to the nature of the phone, this is not always possible; in this case, the settings must be entered manually.
Before you start setting up, you need to find out the APN, username and password for your operator.
To set up a hotspot on an Android phone, you will need:
- Open "Settings".
- Select "Network".
- Click "Mobile network".
- You will need to open "Access Points".
- Check to see if the required operator's APNs have already been created. If there is, select, if not, click the plus sign in the upper right corner.
- You do not need to fill out all the parameters. The user will need to come up with a “Name” (any), enter “APN”, as well as a username and password if the operator sets them. And click on the three dots in the corner, and then “Save”. Some other fields will be filled in automatically, some are simply not needed.
You can also set up APN on an iPhone, for this you will need:
- Open "Settings".
- Select "Cellular".
- Tap “Cellular and Data”.
- In the “Cellular Data” block you need to fill in the APN, username and password.
These are the main reasons why there is no Internet on the phone, but there are also rarer types of problems.
#8 Viruses
Virus programs should not be blamed for all problems, however, they can also become the reason why there is no access to traffic. If the Internet is connected, but does not work on the phone, and money from the account is spent on data transfer, most likely, malicious software is installed on the device.
For mobile OSs, the choice of antivirus programs is small (Norton Mobile Security, Kaspersky Safe Browser, McAfee Mobile Security and several lesser-known programs); in fact, sometimes it’s easier to simply reflash the device (reinstall the system).
#9 Smartphone failure
And finally, the most unpleasant reason why mobile Internet does not work on Android, iPhone or any other system is a breakdown.
Changing the settings will not solve the problem, so you will need to take the gadget for repair and entrust its repair to professionals.
We hope that now any user, with the help of these detailed instructions, can identify the reason why the Internet does not work, and also troubleshoot some problems on their own.
If problems arise with a wet gadget, do not connect it to the mains and stop pressing the buttons. as soon as possible and only then follow the advice in this article.
If you are sure that the inside of the smartphone is dry, feel free to continue.
