A few years ago, fast data transfer required Wi-Fi, but the situation has fundamentally changed. Mobile Internet has become an integral part of any smartphone, and instead of hanging websites, users get decent speed and good coverage. But what to do if the mobile Internet does not work on Xiaomi? How to solve this problem yourself? Now let’s figure it out!
Finding the cause of the failure of the mobile network
To begin with, let’s identify the reasons why the mobile Internet does not work. Most often, it is a software problem, which can be eliminated by properly configuring the device. If the problem is mechanical, here will help a qualified master.
Initially, it does not turn on
Have you bought a new mobile device, and it does not transmit data? It is possible that you have been sold a defective phone. To avoid such unpleasant situations, buy electronics from trusted sellers on foreign sites, or choose good local stores.
If mobile internet cannot be activated on your new device, please read the following points carefully and follow the recommendations. None of the methods helped you activate the Internet. Then urgently contact the store and demand a repair/return of your smartphone.
Poor signal reception
Here it is the coverage area that is to blame. Usually, in the city center, there are no problems. Still, on the outskirts, in villages, and in nature, the quality of mobile communications deteriorates significantly: the Internet freezes, pages do not load, and downloading materials from the web is impossible.
Special attention should be paid to the 4G standard, which is not present in all regions. The solution here is simple: switch to 3G (H, H+), and study the coverage map of your area. Such materials are always posted on the official website of the operator.
You can read more about all generations of mobile telephony on Wikipedia.
Not working after upgrading/self-flashing
Mobile communications may function intermittently if you upgrade to a new operating system or firmware version. With an official update through Three Dots, such malfunctions usually do not occur. The exceptions are developer builds, but the developers eliminate the problems rather quickly.
What to do if the mobile Internet does not work after a manual update on Xiaomi (for example, with MiFlash)? Radical solution – re-flash or roll back to a previous version. Also, the less drastic options described in the next section will help you.
Problem with the SIM card carrier
There may be some problems in the network right now, and the specialists will fix them shortly. If you do not find abnormalities on your device, contact the operator and present the presentations.
Phone settings are lost
And the most trivial reason – the settings responsible for the coordinated work of the mobile network in your smartphone are confused. For example, the wrong communication generation is selected, a new access point is needed, or the traffic limit is exceeded.
What to do if the mobile Internet on Xiaomi and Redmi phones does not work properly
Approached, finally, to the practice. Here we will provide detailed instructions on how to restart the mobile Internet. Be careful and reread each point!
Method 1: Check your SIM card and phone for 4G support
The first thing to do if you want to use LTE is to ensure your phone supports fourth-generation connectivity. Be sure to check your SIM card, your data plan, and your smartphone itself.
All old-style SIM cards only give out 3G; for faster Internet, you need to buy a new SIM card. To check 4G, you enter a special command different for each operator.
You need to do other algorithms:
- Pay attention to the year of issue of the card. SIM cards issued before 2013 do not support the fourth-generation connection.
- The card should have a USIM icon with a small “4G LTE” mark next to it.
- You can also contact the operator or visit the mobile company’s office. The consultants will use your phone number to determine whether 4g is available.
Next, very carefully check the tariff package. It must necessarily be marked with a note about the fourth-generation Internet. It happens that LTE is connected as a separate service. So when you sign up for a new tariff, it is better to tell the operator immediately that you want to use 4G.
And finally, make sure that your smartphone has a module for high-speed Internet. All Xiaomi devices released in the last few years support this function. But it is better to check older models.
LTE may not work correctly on phones aimed at the domestic Chinese market. So buying smartphones designed specifically for China is not a good idea.
Method 2: make sure the SIM card is working and turn on the data transfer
Now you need to ensure that the SIM card is working. To do this, move the card to another mobile device and try to activate the mobile internet on it. If everything is working, the reason is your smartphone’s wrong setting.
The most trivial malfunction may lie in the deactivated data transfer. This is especially true for newly purchased devices.
- Looking for the “Settings” icon on the main screen, go in;
- Scroll down the page to the item “SIM cards and mobile networks” and here, move the slider to the mode “On” opposite “Mobile Internet”. These simple actions help in most cases when Xiaomi loses mobile Internet.
Method 3: removing the control of mobile traffic
Users who buy a package with limited traffic for a month usually limit their internet usage. A firewall is very useful because it allows you to allocate megabytes intelligently. But sometimes, such an option limits to traffic, resulting in the mobile Internet working poorly and giving minimal speed.
- To remove the restrictions, visit “Settings” and the “Security” section.
- Click on the green icon “Traffic ” – “Application Control” and remove all restrictions.
- There may be a ban on certain applications to use 3G/4G. If you have several SIM cards, the tariff plan is set individually, respectively, and the restrictions must be viewed separately.
Method 4: configure the network type yourself
Your phone may support 4G, but the signal usually disappears when there is insufficient coverage or bad weather. As a result, the mobile Internet sometimes stops working and switches to 3G, H, or H+. Because of such jumps, normal speeds are impossible, so choosing one type of network is recommended.
Again you will need “Settings ” – “Mobile data ” – “Network type”. Here you can choose the most relevant and suitable option for you. You can choose from the following options: “Preferably 4G”, “Preferably 3G” and “Preferably 2G (only for calls)”.
It is best to choose 3G, so you get the most stable and generally good Internet. And to save the charge, the second generation will do.
After these settings, the Internet will work only in the selected range. Even with excellent 4G, you will stay on 3G unless you switch back to LTE.
The situation is similar with Wi-Fi. For example, the wireless LAN connection is on, but the Wi-Fi is not working. You won’t be able to go online until you manually select mobile data.
Method 5: Add a new APN access point
If access to the World Wide Web still doesn’t appear, try specifying the settings yourself.
- Go to “Settings ” – “SIM cards and mobile networks”;
- Click on the desired card and select “Access points” in the window “Operator’s network”;
- Now you need to add a new access point or edit the current one, specifying the following data: “APN”, “Operator”, “Username”, “Password” and “Authentication type”. Request this information from your provider and enter it in the corresponding field. That’s all. It’s done.
Method 6: Reset to factory settings or reflash
None of the above options helped, and the Internet does not turn on. Then it’s worth resorting to serious system operations. To begin with, reset your phone to factory settings, making a backup beforehand. Probably, it will eliminate the bug.
Or, there is only a full reflash of the mobile device / call to the service center. Experienced users can install the new shell by following our instructions. It is desirable to choose stable global builds causing the least hassle. On the XDA site, look for detailed information that applies to your particular model.
And for newcomers, we recommend immediately contacting the service center for qualified assistance. You will be given a free repair if the smartphone is under warranty.
Resetting network settings on Xiaomi
On the new models of Xiaomi in the latest versions of MIUI added a useful function of resetting all the network settings of the phone, that is, reset settings:
FAQ
Mobile Internet sometimes stops working for no reason, how to solve this problem?
The first thing to do is to check the coverage map. Perhaps 4G does not work well in your area, and the connection is periodically disconnected. If the reason is a faulty mobile module, then only a master will help.
How to increase the speed of mobile Internet on Xiaomi?
To make the mobile Internet faster, you need to perform a general optimization of the device. Namely: clean the cache, free up permanent storage, and put an ad blocker. These are the general principles by which the performance of the smartphone improves. Such actions do not require root rights. If you want to increase the Internet speed significantly, then you need the SuperUser mode. We will tell you more about these procedures in a separate article.
How to configure the Internet from a particular operator?
Usually, the setting is made automatically after the first sim-card connection. Otherwise, you add a new access point, requesting the data from the provider.
I got root right, and after that, my phone works poorly. What to do?
Delete Super User mode and reset the device to factory settings. This should help.
