How can we solve this problem? Come and have a look with Xiao Bian!
Why there is no signal after changing the card of iPhone 14 Pro
1. The SIM card of the mobile phone is not in good contact with the spring piece of the phone card slot, which causes the circuit of the SIM card to fail to work, and the mobile phone cannot communicate with the network base station. At this time, you can remove the SIM card, wipe the golden finger of the SIM card with a clean cotton cloth, and then reinstall it.
2. Because the application software installed on the mobile phone is incompatible with the system, the system software turns off the modem in the signal processing circuit of the mobile phone. At this time, you can turn off the mobile phone and restart it. The modem in the signal circuit of the mobile phone will restart. After the signal is normal, delete the suspicious mobile application software installed before the problem.
3. The SIM card of the mobile phone is not registered in the network. At this time, you can insert the SIM card into another mobile phone. If no service is also displayed, it is the reason of the SIM card.
4. Accidentally, the SIM card of the mobile phone fails to reconnect to search the network and register after there is no signal in the area covered by the network signal. In this case, you can manually search for network registration under Settings - General - Network - Network Operator menu.
5. The reason why the signal of the network operator of the mobile phone SIM card cannot be covered is that you can change the location to an open area, and then check the display of the mobile phone signal grid. If the display is normal after changing the location, you can call the service phone of the network operator for feedback and complaints.
6. The phone card has been used for too long. With a valid certificate, you can go to the local business hall to apply for a new card.
