Mobile phones can surf the internet, but they can't make phone calls and send text messages. What happened?

First, the common reasons why mobile phones can't answer the phone and their solutions are as follows:

1, check whether the mobile phone is in arrears, and suggest paying for recharging;

2. Check whether the mobile phone is set with call forwarding, flight mode on and call barring. Suggest canceling and try again;

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

4. Try to restart or change the phone to see if you can answer the phone;

5. Bring the mobile phone card to the local business hall for testing or replacement.

2. If you mean that the mobile phone can't send short messages, you can try to restart the mobile phone or change the mobile phone to test whether there are any of the following situations:

(1) SMS center number is set incorrectly, please re-enter the correct SMS center number;

(2) No signal or insufficient battery power;

(3) The mobile phone shields the short message sending function;

(4) blacklisted by SMS;

(5) Insufficient quantity balance.

If you still can't solve the problem after self-help troubleshooting, it is recommended that you contact the local manual customer service to help verify the handling.
