When we use mobile phones, we may find that the 4G signal is full, but we can't connect to the network, and the mobile phone can't use the Internet, causing us to be unable to do a lot of things.

Finally, if the above methods are useless, we can generally restart the mobile phone and go online, especially if there is no network after just recharging.

The reason behind why the 4G network is getting slower and slower, and the signal is full, and the Internet cannot be connected is too realistic.

1. Troubleshoot the reason for the failure of the mobile phone, you may leave the area covered by the 4G signal transmitter, so there is no 4G network.

2. If it is confirmed that it cannot be connected in the 4G signal area, one is the mobile phone system, or the card, and the other is that the software is too much to cause the machine. Or the phone has not been turned off for too long, and a lot of software fragments are retained.

Solution, shut down and restart first, clean up the running memory, and confirm that the chip card is in good contact with the phone.

It is related to the coverage of the 4G network in your area, 4G is not fully covered in China, and it has nothing to do with mobile phones.
