A modern smartphone is impossible to imagine without access to the global network, and devices from Xiaomi are no exception. Often users are faced with a situation when after installing a new one. SIM-If you have a card or a change of operator, the automatic settings do not come or work incorrectly. APN, It's a standard procedure that takes only a few minutes, but requires careful input of characters.
The MIUI or HyperOS shell interface may vary slightly depending on the Android version, but the logic of the system modules remains the same for all models, whether it is a budget Redmi or flagship Xiaomi. We will analyze a step-by-step algorithm of actions that will help you configure GPRS/3G/4G even in the absence of automatic messages from the operator. The correct configuration will ensure a stable speed and no connection breaks in the way.
Before you start manually entering settings, make sure that the problem lies in the settings of the phone, not in the plan or network coverage. Sometimes it is enough to just restart the device or switch modem. In this article, we will examine all the nuances of the connection, including hidden menus and specific settings for different carriers.
Primary inspection SIM-maps and physical connections
The first step should always be to diagnose the physical condition of the SIM card and slot. Make sure the chip is installed correctly, the contact area is not contaminated, and the tray is tightly closed. If the device supports two SIM cards, check in the settings menu which slot is assigned to mobile traffic, since the Internet often does not work due to the fact that data tries to go through the card without a tariff.
Go to the Settings section and select a paragraph SIM-You need to activate the switch slider for the SIM card you want. Notice the indicators at the top of the screen: the G, E icons appear, 3G or 4G/LTE It indicates that the phone sees the operator's network, and if only the signal icon without letters is on, then the radio module is working, but the data channel is not configured.
💡
Use an adapter to SIM-cards only as a last resort, as a thickened card can get stuck in the tray or damage contacts inside the smartphone.
In some cases, you need to re-register the network, turn on Flight mode for 10-15 seconds, and then turn it off, which causes the communications module to re-enter the authorization procedure at the nearest cell tower, which often solves the problem of stuck connection.
Manually configuring the APN access point
If you don't have automatic settings, you'll have to create a new hotspot manually, which is key to getting online, because it tells the phone the gateway through which to send data packets, and writing an APN address is the most common cause of broken Internet when you have a paid rate.
To start settings, go on the Settings path → SIM-maps and mobile networks → Choose yours. SIM-map → Access points (APN). In the list that opens, press the button. + Or a new access point in the bottom or top corner of the screen, and you'll see a form that you need to fill in your carrier's data.
☑️ Verification of parameters APN
In the Name field, you can type in an arbitrary name, such as "MyInternet." The Access Point (APN) field is critical: the operator's domain name (such as Internet.mts.ru or simply the Internet) is entered here. The remaining fields, such as username and password, are usually left blank unless the operator has indicated otherwise. Once completed, be sure to click the menu (three dots) and select Save, and then activate the created point by placing a marker next to it.
⚠️ Note: When entering the address APN Do not use spaces and capital letters unless they are specified in the official requirements of the operator, as the system may consider this as a syntax error.
Configuration of parameters for the main operators
Different cellular operators use different gateways to connect to the Internet. Below is a table of current settings for the largest operators operating in the region. Use this data when creating a new access point if you don't know the exact parameters.
| Operator. | APN (Access Point) | User name | Password. |
|---|---|---|---|
| MTS | internet.mts.ru | mts | mts |
| Beeline | internet.beeline.ru | beeline | beeline |
| MegaFon | internet | (empty) | (empty) |
| Tele2 | internet.tele2.ru | (empty) | (empty) |
| Yota | internet.yota | (empty) | (empty) |
After entering the data from the table, remember to save the profile and choose it to be active. Sometimes the MIUI system can ignore the changes if the network settings were not completely reset, in which case it is useful to delete old, broken APN profiles, leaving the newly created one.
💡
A properly entered APN is 99% of the success in setting up mobile Internet, the rest of the settings are usually adjusted automatically.
Network modes and preferred type management
Speed and stability of the connection directly depend on the type of network you choose. Xiaomi smartphones have a wide range of modes of operation of the radio module. Go to the Preferred network type menu in the SIM card settings section. Here you will see options from 2G to 5G (if supported).
For most modern tasks, the optimal choice is preferably 4G or LTE. If you are in a low-reception zone, the phone can constantly try to catch a fast signal, losing communication altogether, in such cases it makes sense to temporarily switch to 3G or 2G to at least send messages, or use the 4G Only feature to prevent switching to EDGE/GPRS.
The hidden engineering menu allows you to access the more subtle settings of the radio module. By entering the phone application code ##4636##, you will be taken to the testing menu. Select phone information and find the drop-down list Set your preferred network type. Here you can choose LTE Only mode, but be careful: this mode may not work incoming calls unless VoLTE technology is enabled.

Resetting network settings and additional solutions
If manually configuring APN didn't help, there may have been software errors in the system, resetting the network settings will return all the connection settings (Wi-Fi, Bluetooth, mobile data) to factory values. This action will not delete your personal files, contacts or applications, but you will have to re-enter passwords from Wi-Fi networks.
To perform the reset, go to Settings → Connection & Sharing → Reset Wi-Fi, mobile networks and Bluetooth. Press Reset and confirm the action. Once the reset is done, the phone will try to reconfigure the operator, which often solves the problem.
Also worth checking is whether traffic savings or background activity limitations for system services are included.In the Data Use section, make sure that the Android System or MIUI Daemon system process does not prohibit data transfer in the background.
Diagnosing problems with coverage and SIM-card
Sometimes the problem lies not in the settings, but in the physical state. SIM-If the card is many years old, its contacts could oxidize and the chip could wear out. Try to wipe the chip with a soft dry cloth. If you can, insert the SIM card into another phone: if the Internet does not work there, then you need to change the card in the cabin operator.
Note the coverage area: In basements, metal structures, or remote rural areas, the signal may be unstable, and in these places, the phone may indicate the network, but the packet data will not pass due to the high rate of transmission errors.
⚠️ Note: Do not use scissors to trim SIM-cards up to the size of the Nano-SIM, as this often damages the contact path and leads to complete card inoperability.
