Why is there no signal on iPhone 14 after card replacement
As the most popular smartphone recently, the iPhone 14 has gained considerable sales on various platforms since its official launch in September. I believe many young friends who bought it early have already got it and started using it. However, some users have no signal after changing the card of the iPhone 14 or installing a new phone card. What's the matter? Now let's make a detailed introduction!
Why is there no signal on iPhone 14 after card replacement
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.
The above is the solution to the problem that there is no signal after the iPhone 14 card is replaced. The signal of this phone is quite good. Generally speaking, this problem occurs because it is not properly placed. Just reinstall it. If the problem is not solved according to the above method, it is recommended that you go directly to the offline store to find a staff member to solve it!
