Mobile phones can't receive text messages and phone calls.

1. According to the information you provided, if your mobile phone can't send and receive short messages, you can try to restart or replace your mobile phone for testing to see if the following conditions exist:

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

2. Because the system is busy during the holiday short message sending peak period, it is suggested that you try again later or avoid the sending peak period;

3 The sending format is incorrect. If you send a short message to PHS users, you need to add the area code before the number;

4 SMS sending time exceeds 24 hours;

5. The mobile phone shields the short message sending function;

6 blacklisted by SMS;

SMS Inbox and Outbox are full.

2. If your mobile phone can make a call, but it can't answer now, it doesn't rule out that your mobile phone is set with call forwarding, so I suggest you cancel call forwarding and try again.

3. If you need to cancel call forwarding, you can enter ##002# in the dialing interface of your mobile phone and dial again to cancel all call forwarding. After success, the screen will prompt that the operation is successful.

4. If the problem cannot be solved after self-help troubleshooting, it is suggested that you can contact Unicom's manual customer service for verification. The actual situation is subject to local policies.
