I can't get calls or send text messages.

Common reasons why mobile phones can't answer calls and their solutions are as follows:

First, check whether the mobile phone is in arrears, and it is recommended to pay for recharging;

2. Check whether the mobile phone is equipped with functions such as call forwarding, flight mode and call barring. It is recommended to cancel and try again;

3. Check whether the function or signal of the mobile phone is normal. It is recommended to change the location and try again.

4. If it can't be used when roaming to other places, it is recommended to check whether the local network signal is normal and whether the number has been roaming.

5. Try to restart the phone or change the phone for testing;

6. You can take your mobile phone card to the local business hall for testing or replacement.
