Can't Apple make phone calls and send text messages?

Causes and solutions of abnormal telephone calls;

1. Check whether the phone is set with call forwarding, airplane mode on, call barring, etc. Suggest canceling and try again;

Second, in a remote or closed location, the signal is weak, so you can try to answer the phone in another location;

Third, the new number needs to be activated before it can be used normally, and the status of the local number can be queried;

4. This number has been stopped, which affects the call. You can check the number information to know the status of the number. If it is not normal, you need to restore the normal state of the number before you can answer the phone.

Please check whether the mobile phone is in arrears. If it has been recharged, you can check the recharge status.

6. Please check whether the mobile phone card is damaged or inserted incorrectly, and you can go to the local business hall to test or replace the mobile phone card;

Seven, I suggest you can restart or switch flight mode and try again. If you still can't answer the phone normally, you can also change your mobile phone for testing.
