Receiving text messages will be short and there will be no signal.

It is recommended to operate as follows:

1, check whether you can make a phone call, and rule out whether the phone bill is insufficient or the network signal is unstable.

2. It is recommended to replace the mobile phone or SIM card for testing.

3. Find out whether the surrounding users have this situation. If the surrounding users also have this situation, they can report it to the operator's customer service hotline.

4. It is recommended to back up data (contacts, pictures, etc.). ) and restore the phone to the factory settings.

5. If there is something wrong with the mobile phone, I suggest you take the purchase invoice and replacement card and take the mobile phone for after-sales inspection.
