Xiaomi’s modern smartphones are famous for their smart MIUI (or HyperOS) system, which automatically detects the operator’s SIM card and loads the necessary configurations. However, despite the advanced artificial intelligence of the shell, sometimes failures occur, especially when installing a new SIM card or after updating the Android operating system. In such situations, the user faces a lack of access to the 4G network, even if the signal is confidently captured. This is a classic situation where manual adjustment of access point parameters is required.
For MTS subscribers, mobile internet is critically important, as many services, messengers and apps depend on a stable connection. Incorrect APN (Access Point Name) settings can cause the Internet to run slowly, break down or not work at all, despite the availability of a paid tariff. Xiaomi owners need to know where to look for these hidden menus, since the manufacturer’s interface is different from stock Android.
In this article, we will take a detailed look at the manual configuration process, look at specific parameters for different firmware versions, and learn how to fix typical errors. You will learn how to enter data correctly so that your smartphone begins to “fly” on the LTE network. This knowledge will be useful for anyone who wants to have full control over their device and not depend on automatic, but not always correct operator settings.
Preparation of the device and checking the SIM card
Before you delve into the complex settings menu, you need to make sure that the physical health and proper installation of the SIM card. Often the problem lies not in software failures, but in the banal contact or tariff status. Make sure that your SIM card is active, not locked and on balance there are funds or packet traffic. If the card is too old and does not support 4G, no settings will not help - you will need a replacement in the cabin.
In Xiaomi smartphones, SIM slots can be combined. Make sure the card is mounted tightly and in the right slot if you use two SIM cards. Sometimes the system can confuse slots when determining the type of network. It is also worth checking whether data is turned on at all in the "curtain" of notifications. The "Mobile Internet" slider should burn in blue, and the network icon in the status bar should display a 4G or LTE icon.
The important step is to check coverage, and even a perfectly tuned phone won't be able to pick up a signal if you're in a dead zone, try moving to another location or rebooting the device so that it re-enrolls in the base station network, and reboot is a universal method that solves up to 80 percent of the temporary network conflicts in the operating system.
Automatic configuration via SMS and applications
The easiest way to get the right parameters is to trust the automation. The MTS operator provides the ability to request configuration data through special configuration data. SMS-This is a standard procedure that works on most devices, including Xiaomi, but be careful: sometimes automatic messages may be delayed or not used by the system due to security restrictions. MIUI.
To get the settings, send an empty message or word Internet to the short number 111. SMS You have to open the message and click "Install" or "Apply" button, and Android will ask permission to change the settings of the network, we agree. In some cases, you may need to enter the PIN-code, which is usually 1111 or 0000, but is often specified in the message itself.
What to do if the SMS does not arrive?
An alternative method is to use the official “My MTS” app. Once logged in, the app often pops up with a suggestion to configure the internet for the device. This is a more modern and reliable way, since the app itself identifies your Xiaomi model and the Android version, offering the most relevant profile. The app also allows you to monitor traffic and connect options, which makes it a useful tool in everyday use.
Manually configure APN access point on Xiaomi
If the automatic methods don't work, you'll have to manually adjust. This is the most reliable way to ensure that there are no unnecessary or conflicting parameters in your profile. On Xiaomi smartphones, the path to settings may vary slightly depending on the version of the shell, but the logic remains the same. You need to get into the mobile menu.
To start, open the “Settings” and go to the section «SIM-Select the MTS SIM card that requires configuration (APN)». Inside, you'll see a list of existing profiles. To create a new one, click on the plus in the upper right corner or the New Access Point button. Here, you need to carefully fill in a few fields.
☑️ Filling parameters APN
Key fields are “Name” and “Access Point (APN)». In the “Name” field, write an arbitrary name, for example, MTS LTE, So you can easily find a profile» (APN) Please specify Internet.mts.ru. The remaining fields, such as “Username” and “Password”, are filled with the value of mts (line letters «MMSC» leave empty unless the operator has indicated otherwise, as they may slow the connection.
After filling in all the fields, be sure to click the menu (three dots in the corner) and select Save. Just go back is not enough - the profile is not activated. Then go back to the list of access points and check the tick (radio button) against the created MTS LTE profile. Now try to turn off and turn on the mobile Internet or put the phone in flight mode for 10 seconds.
Parameter table for different types of networks
Different data technologies may require slight differences in settings, although for most modern Xiaomi smartphones, universal parameters are enough. Below is a table that will help you understand what values are relevant for your case. Note that it is critical for 4G/LTE to correctly specify the type of protocol.
| Parameter | Value for 3G/4G | Value for 5G (SA/NSA) | Note |
|---|---|---|---|
| APN (Access Point) | internet.mts.ru | internet.mts.ru | Basic parameter |
| User name | mts | mts | Register important |
| Password. | mts | mts | Register important |
| Type APN | default,supl | default,supl,xcap | For VoLTE/VoWiFi |
| Protocol | IPv4/IPv6 | IPv4/IPv6 | Dual Recommended |
In the field "Typical" APN» (APN Type) is best to write the default value,supl. Supl parameter is necessary for correct operation. GPS-navigation over the mobile network. If you want to use VoLTE functions (calls through the mobile network) LTE) Or Wi-Fi Calling, the list can be expanded, but the basic values ensure a stable Internet. IPv4/IPv6, This ensures the best compatibility with modern servers.
You should not change the values in the fields MCC and MNC if you are not sure whether they are correct for your region. These codes identify the operator and the country. At Xiaomi, they are usually substituted automatically when you install a SIM card. For MTS Russia, this is usually MCC 250 and MNC 01. Changing these codes can lead to a complete loss of the network.
💡
Save screenshots of the original settings before changing them. If the new configuration doesn't work, you can quickly get it back to normal by just checking the photo.
Advanced settings and network type selection
Once you set up the access point, you need to make sure that the phone itself is set to use the fastest communication standards «SIM-maps and mobile networks" find the item "Preferred type of network. To fully use the capabilities of MTS, the value should be selected here. LTE or 5G/LTE/3G/2G (motor-car).
Sometimes users are faced with a situation where the phone gets stuck on EDGE (E) or 3G (H+), ignoring the presence of 4G. In such cases, the forced mode choice helps. Try switching only to LTE, checking for the appearance of the 4G icon, and then returning back to automatic mode, which forces the modem to re-enter the LTE network.
⚠️ Note: Compulsory inclusion only 4G/LTE This can lead to the fact that incoming calls will disappear in areas of poor coverage if VoLTE technology is not activated. LTE without VoLTE, the phone must be able to switch to 3G/2G talk.
Also worth a look at the Advanced Settings settings (if available in your version of MIUI) may be the "Enable VoLTE" switch. To function, it must be supported by your tariff and region. Enabling VoLTE greatly improves sound quality and allows you to talk and use fast Internet at the same time.
The solution: Why the Internet doesn’t work
Even after you set it up properly, there can be problems, and let's look at the most common ones, and if there's a 4G icon but the pages aren't loading, check if Traffic Savings or Data Limit is on. Xiaomi has a Background Connection Limit feature that can block your browser from the background. Turn it off for the period under test.
Another common cause is static. IP-In the access point settings (APN) Find the "Protocol" field IP» or proxy settings. Make sure that there's no static in the system. IP. All fields should be empty or stand in dynamic mode» (DHCP). Static IP, left from the old operator or corporate SIM, will conflict with the network of MTS.
💡
The most common mistake is a typo in the address of the access point (APN). Check that there is exactly Internet.mts.ru, without www, http:// idle.
If nothing works, try resetting your network to factory settings. In the settings menu, look for Connect and Sharing (or "Additional") and select Reset your Wi-Fi, mobile and Bluetooth settings. This action will delete all saved Wi-Fi passwords and Bluetooth points, but return the network settings to their original state, which often resolves software conflicts.
The Impact of Android Version and the Firmware Region
It is worth noting that owners of global versions of Xiaomi (Global ROM) and Chinese versions (CN ROM) may have menu differences. In Chinese firmware, the path to APN is sometimes hidden deeper or requires entering special code into the engineering menu. However, the standard path through SIM card settings should work everywhere. If the APN menu is not available (gray), then administrator rights are limited, and alternative activation methods should be sought.
Android version also plays a role. Android 12, 13 and 14-google have increased security requirements, and some old methods of editing system files to change APNs have stopped working without root rights. Fortunately, the standard settings interface is usually enough. If you upgrade from Android 11 to 14 and the Internet is gone, create a new access point from scratch, without editing the old one, since old profiles may contain incompatible settings.
⚠️ Warning: Don't download third-party "to set up the internet" apps from the Play Market.They often contain ads, require extra permissions and do the same thing you can do manually in 2 minutes in your phone's settings.
In conclusion, setting up APN correctly is the foundation of a stable mobile experience. For MTS and Xiaomi devices, the combination of Internet.mts.ru and Mts login/password is the gold standard. Keep that data, and you can always quickly restore the Internet to any device.
