Suddenly, the mobile phone can't get through, and the short message can't be received, and the mobile data is invalid.

This is the result of the interruption of the communication network. Just dial the other party's number. Here are ways to deal with this problem frequently:

1. Call the operator's customer service phone and ask the customer service to refresh the personal call data.

2. Turn off the phone, restart it, and reset the phone call data.

3. The convenient way is to put the mobile phone in airplane mode, and then turn it off to reset the call data.

4. Clean up mobile phone garbage and free up running space? Keep the phone running smoothly.
