Hello, everyone. The meeting will answer your questions. Apple 7 shows what no service is all about. Many people don't know what it is like when Apple 7 shows no service. Now let's take a look at it.

Answer:

1. First, take out the mobile phone card and check if there is something wrong with the mobile phone card, or insert another phone card to check whether the mobile phone card is unavailable, resulting in the failure of the phone service.

2. Open the settings, find the flight mode option in the settings, click the button on the right, and close after a few seconds.

3. It is still unable to solve the problem of lack of service, so it is suggested to take it to the official repair shop for maintenance.

4. The reason why the mobile phone has no service.

5. The SIM card of the mobile phone has poor contact with the shrapnel in the slot of the mobile card, which leads to the circuit failure of the SIM card and the inability to communicate between the mobile phone and the network base station. At this point, you can remove the SIM card, wipe it with a clean cotton cloth, and then reinstall it.

6. Because the application software installed on the mobile phone is not compatible with the system, the system software turns off the modem in the mobile phone signal processing circuit. At this point, the phone can be turned off and then rebooted. The modem in the cell phone signal circuit will restart. After the signal is normal, the suspicious mobile phone applications installed before the problem will be deleted.

7. The SIM card of the phone is not registered in the network. At this point, the SIM card can be plugged into another mobile phone. If it also shows that there is no service is the reason for the SIM card.

This is the end of this article. I hope it will be helpful to all of you.
