Calls don't go through, mobile Internet is off, and rebooting doesn't help. Is the situation familiar? Network problems on Xiaomi smartphones are more common than it seems – and the reasons can lie in software failures and hardware malfunctions.

In this article, we will look at all possible causes of network loss, from the banal “on-plane mode” to complex firmware errors.

Basic checks: what to do first

Before digging deep into your settings or carrying your phone for repair, follow 5 mandatory steps. In 60% of cases, the network returns at this stage:

• 🔄 Restart the phone with a long power button hold. MIUI 14+ Sometimes a “hard” reboot helps: pinch the power + Volume up for 10 seconds.

• 📡 Check the network coverage. Go to the operator's website (for example, the Beeline coverage map) and check if there are any problems in your area.

If after these actions the network did not appear, move to the next section. MIUI 13 and below are sometimes confused settings APN — You will have to manually adjust them (more on this below).

⚠️ Attention: Network reset will delete all stored Wi-Fi passwords and associated Bluetooth devices. → The phone. → Resetting settings → Resetting Wi-Fi, Mobile Network and Bluetooth.

3. Software failures: when firmware is to blame

If the network is missing after the update MIUI Or custom firmware installations -- the problem is almost certainly with the software:

• 🔄 If the network is gone after the update, try to roll back to the previous version. MIUI through settings → The phone. → Updating the system → Three points. → Select the update package (you need an old firmware file).
• 🛠️ Cache cleanup. Go to Settings. → Annexes → Application management → Three points. → Show system-based → Phone services and clear the cache.

For Xiaomi models on Qualcomm Snapdragon (e.g, POCO F3, Redmi K40) There's a hidden engineering mode where you can test the communications module to get there:

1. Please dial in the phone app: ##4636##.
2. Select Phone Information.
3. Scroll down to Set preferred network type and try different modes (e.g, LTE only).

⚠️ Note: If the engineering menu is in the section SIM Status is Unknown instead of Status. IMEI — This is a sign of hardware failure (a communication module or antenna is damaged), in which case only the service center will help.

4. Hardware problems: when to carry for repair

If none of the software methods worked, it's probably a hardware problem, and here are the main signs of a hardware malfunction:

On Xiaomi models with a metal body (for example, Mi 11 Ultra, Black Shark 4), antenna contacts often suffer - they oxidize or depart when falling.

1. Remove the back cover (on models with a non-removable battery, it is better to entrust this to a specialist).
2. Look at the golden pads on the motherboard – they should be clean, without black spots.
3. If the contacts are oxidized, they can be gently cleaned with a stripe or alcohol solution.

Important: If the phone falls into water or is subjected to a strong vibration (for example, in a car without a mount), the probability of hardware failure increases to 90%.

💡

Before visiting the service center take a photo IMEI phone (printed on a box or under the battery) and save the purchase check, which will speed up the diagnosis and help avoid changing parts.

5.Problems with the operator: blockings and restrictions

Sometimes the network goes missing because of the operator's actions, not the phone's fault.

• 🚫 Lockdown SIM-Check the balance and status of the card through the operator's personal account.
• 📵 Restriction of services (for example, if you have not used a number in a long time) MegaFon and Beeline have a rule: if there was no activity for 60 days, services are suspended.
• 🌍 Roaming restrictions: If you are abroad, the operator may have turned off roaming due to lack of funds or tariff changes.
• 🔄 Change of network technologies: some operators (e.g. Television)2) shut down 3G favorably 4G/5G. If your Xiaomi doesn’t support new frequencies, your network may be lost.

To check the status SIM-map:

1. Call the operator’s short number (for example *111# for MTS, *105# for Beeline).
2. If the call doesn't pass, insert it. SIM different phone.
3. Check the status of the card in your personal account or through the operator's application.

If the operator has confirmed the blocking, the problem can be solved:

• Paying the debt (if any).
• Providing documents for unlocking (if the card is blocked at the request of bailiffs).
• Activating the service "Mobile office" or "Personal account" (sometimes operators block cards without active digital services).

⚠️ If you bought Xiaomi with your hands, check if it is blacklisted. IMEI. Stolen or lost phones are often blocked by operators at the request of the owner.

6. Features of models: what breaks most often

Some Xiaomi smartphones have typical network problems related to their design, and here are the most common cases:

Nana POCO F1 And other models with the Snapdragon 845 are often bugged when the phone forgets network settings after the upgrade:

1. Enter the engineering menu: ##4636###.
2. Select Phone Information.
3. In the Set Preferred Network Type section, select LTE/TD-SCDMA/GSM auto.
4. Reboot the phone.

For Xiaomi owners with MediaTek (e.g. Redmi) 9A, POCO C31) There is a separate instruction for resetting modem settings:

1. Install the MTK Engineering Mode application.
2. Go to MTK Settings → BandMode.
3. Choose Auto for all ranges.
4. Save and restart the phone.

💡

If your Xiaomi is older than 2019 and stopped catching the network after the update - with a high probability the problem is incompatible with the firmware with the hardware. MIUI.

7. Alternative solutions: if nothing helps

If all of the above methods do not work, try non-standard approaches:

• 📲 Use the second slot for SIM. Sometimes the main slot fails and the spare is working normally.
• 🔌 Connect to Wi-Fi and update your firmware over the air. Sometimes the fresh version. MIUI modem-corrects.
• 🛡️ Turn it off. VPN Some applications (e.g. Kaspersky, NordVPN) block network connections.
• 🔄 Reset the settings to the factory via Recovery. This is a deeper reset than through the menu: 1. Turn off the phone. 2. Press Volume up. + Power. 3. From the Recovery menu, select Wipe Data → Wipe All Data. 4. Confirm and wait for the reboot.
• 📡 Buy the outside. 4G-If the phone is not repairable at all and the network is urgently needed, USB-modem (e.g. Huawei) E3372) will be a temporary solution.

If you suspect that the problem is the firmware, but do not want to carry the phone to the service, you can try reflashing only the modem (without losing data).

1. Download a modem file for your model (search on request «[model] modem firmware»).
2. Fastboot is a fastboot flash modem NON-HLOS.bin
3. Reboot the phone.
