Modern Xiaomi smartphones are famous for their clever shell MIUI and its modern version of HyperOS, but automatic configuration of mobile operators networks sometimes fails. Users often face a situation where the SIM card is determined, the signal is there, but access to the World Wide Web is absent. This is especially true when the device is first activated or after resetting to factory settings, when the operator’s automatic parameters did not have time to boot.
In this guide, we will discuss how to manually and correctly configure MTS mobile Internet on your device, not only will we look at standard APN access point settings, but we will also touch on hidden settings that can affect the speed and stability of connection in 4G and LTE networks.
Following this guide will help you avoid common mistakes, such as the wrong type of protocol or the lack of the right APN.You will get stable access to messengers, navigation and streaming services using the capabilities of the Megafon network, Beeline or, in our particular case, MTS.
Preparation of SIM-card and tariff check
Before you get to the complex settings menu, you need to make sure your SIM card is ready for the Internet, and often the problem is not the phone’s software, but the lack of operator-side service or a physical chip malfunction.
Make sure your data plan has activated a data service. For MTS subscribers, it can be a gigabyte package within the main tariff or a separate Internet option. If you use the old tariff without the Internet, connecting to the access point will not work until you change the terms of service.
It's also worth checking the physical condition of the SIM card, and if the chip has visible damage or oxidation, the phone can identify the network for calls, but it can't maintain a stable phone. IP-Connection. Put the SIM card in another phone to make sure the Internet is working there. If the problem persists, contact the salon to replace it. SIM new-support 4G.
⚠️ Note: Before setting up, make sure that your account has funds or a subscription fee is valid. In roaming (even within the country, if it is another region), Internet access can be blocked automatically to avoid accidental debiting of funds.
The balance and condition of services are checked through USSD-For MTS, the universal code is *100# or *111#. After dialing the command, a menu will appear on the screen where you can see the rest of the traffic and active options.
Automatic setting via SMS from the operator
The easiest and fastest way to get the necessary parameters is to use the service of automatic configuration. MTS operator has a database of profiles for most popular models, including Redmi, POCO and Xiaomi.
To initiate sending settings, send SMS You'll get a message from the Internet to the short number 1676. SMS-It's important not to delete this message right away, but to wait for it to be processed by the system.
When you receive a message, you'll see a notification on your smartphone screen that you've received a configuration, click on it, then select "Install" or "Accept." MIUI can request permission to change your network settings -- confirm the action. The phone automatically prescribes the APNs, username and password you need.
- 📲 Send the word Internet to 1676.
- 📨 Wait for the incoming message with settings from MTS.
- ✅ Click "Install" in the window that appears.
- 🔄 Restart the device to apply changes.
If the automatic setting didn’t work or an error message came in, it could mean that your phone model is too new and hasn’t been entered in the carrier’s database yet, or you’re in a low coverage area, in which case the only correct solution would be manual adjustment.
Manually configure APN access point on Xiaomi
Manual settings are the most reliable method that is guaranteed to work on all devices, regardless of the firmware version or year of release. You will need to enter the exact data that the operator provides to access the network.
To start, go to the settings menu of your smartphone. The path may vary slightly depending on the version. MIUI, But it usually looks like this: Settings. → SIM-maps and mobile networks → Choose yours. SIM-map → Access points (APN).
In the list that opens, click the New Access Point button or the + icon in the upper right corner, and the form that you need to fill out will open before you. Be careful: the register of letters matters, especially in the dot name field.
☑️ Verification of parameters APN
Fill in the fields with the following data:
| Parameter | Meaning | Note |
|---|---|---|
| Name. | MTS Internet | Any convenient name |
| Access Point (APN) | internet.mts.ru | Critically important |
| User name | mts | In line letters. |
| Password. | mts | In line letters. |
| Type of authentication | PAP or CHAP | Usually PAP. |
The remaining fields, such as proxy, port, MCC, and MNC, are best left empty or unchanged if they are already filled with the system. After entering the data, be sure to click the Save button (usually three dots on the menu or the button at the bottom of the screen) and select the created access point by placing a marker next to it.
⚠️ Attention: Type field APN" (APN Type) in some versions of the firmware you need to explicitly prescribe default,supl. If you leave this field empty, the Internet may not work or work unstable.
What to do if the fields are dropped?
Network mode setting and preferred type
Once you have successfully entered the APN settings, you need to make sure that your phone is configured to use modern communication standards. If you select 2G Only or 2G/3G mode in your settings, you will not be able to use 4G/LTE high-speed Internet, even if the tariff allows it.
Return to the Settings menu → SIM-maps and mobile networks → Preferred network type. Select "Preferred" option here LTE" or "5G/4G/3G/2G (This will give the smartphone modem the command to search for networks with the highest possible speed.
It's worth noting that in some regions, 4G coverage can be unstable, and if you're in a low signal zone, the phone can switch between 3G and 4G all the time, causing connection breaks, so it makes sense to force 3G mode temporarily for stability, even though the speeds will be lower.
For advanced users, there is a hidden Android engineering menu that allows you to fine-tune the radio module. To get there, open the Phone app and type ##4636##. In the menu that opens, select Phone Information and find "Install preferred network type."
- 📶 LTE Only - forced 4G (Internet can disappear if there are no calls via VoLTE).
- 🌐 LTE/TD-SCDMA/UMTS/GSM — standard-mode.
- 📉 GSM only 2G (fire-saving).
Use of the engineering menu requires caution. Do not change the values that are not sure, as this can lead to a complete loss of communication, which can only be restored by resetting settings or flashing.
Resolving Typical Connection Problems
Even with the right settings, there can be situations where the H+ or 4G icon is on and pages are not loaded, which can be due to a conflict of software settings, VPN operation, or Android network stack failures.
The first thing you need to do is check if you have a VPN or proxy enabled. Many antivirus and traffic-saving apps create virtual tunnels that block normal connections. Disable all of these services and try to open a website.
The second step is resetting your network settings, and this action will not delete your personal files, photos or contacts, but will return all network settings (Wi-Fi passwords, Bluetooth and mobile network settings) to factory settings. → Connection and sharing → Reset Wi-Fi, mobile networks and Bluetooth.
If that didn't work, try extracting the SIM card, erase the contacts and paste them again, and check the date and time on the device - an incorrect date can cause security certificate errors, which will cause browsers to refuse to load pages.
💡
If the internet is gone after a MIUI update, try switching the network mode to 3G, waiting 10 seconds, and then back to LTE. This often restarts the network module without restarting.
⚠️ Note: If you have optimized apps installed on your phone (Clean Master, DU Battery and the like, they can aggressively close the background processes of the system that are responsible for the connection.
Optimizing traffic flow and speed
Once the internet is up and running, it’s worth considering saving it, especially if your plan has gigabyte limits. MIUI’s shell has powerful traffic control tools built in.
Go to the Security app (green zipper icon) and select Data Transfer, where you'll see statistics for each application, you can set limits, deny Internet access to individual programs, or limit background data transfer.
You should also pay attention to the Traffic Saving feature, which when activated, will compress images in the browser and limit background synchronization, which can significantly extend the life of your traffic pack at the end of the month.
For maximum speed in games or when downloading large files, you can activate the Game Turbo mode, which prioritizes network traffic for the running application, limiting the background processes of other programs.
💡
Setting up the APN and choosing LTE mode is 90% of the success, and the rest of the problems are usually solved by rebooting or resetting network settings.
