Why there is no signal after changing the iPhone 14 Pro Max card
In terms of the most popular smartphones recently, the iPhone 14 pro max phone must be one of them. It not only uses the most powerful processor in the industry, but also has a very high-end camera configuration. The 48 megapixel camera can be said to break the traditional configuration of the iPhone. In order to facilitate everyone to get started with this phone at the first time, Xiao Bian has sorted out the solution to the problem that there is no signal after changing the card for this mobile phone. I hope you like it!
Why is there no signal after changing the iPhone 14 Pro Max card
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.
In the 20 rounds of 3D Mark's Wild Life Extreme Stress Test, the best cycle score of iPhone 14 Pro Max is 3359, the lowest cycle score is 1887, and the stability is only 56.2%. In the stress test of the Wild Life Stress Test, the best cycle score is 9845, the lowest cycle score is 6257, and the stability is 63.6%. The performance is average. It may be that the high temperature of the phone limits the performance of the phone.
In terms of theoretical performance, the performance of the iPhone 14 Pro Max is not much better than that of the previous generation A15, but even so, the A16 chip is still the strongest mobile phone chip. In the game of Genshin Impact, although the iPhone 14 Pro Max already supports the 120 frame mode, even if 120 frames are enabled, the game will still run at 60 frames. Adjust the game image quality to extremely high, and set the frame rate to 60 frames. In the early stage, the game can still run at 60 frames. However, if the game time is too long, the game frame rate will decline, and the screen brightness will also darken.
The above is the solution to the problem that there is no signal after the iPhone 14 pro max card is replaced. Although the price of this phone is very expensive, and the price reduction of this Double 11 activity is not too high, it is still very worthwhile to start. After all, the performance is here. If you don't care about the price, you guys are very recommended to buy it!
