The phone can't get through, and the text message can't be sent.

1. If this number is used normally, you can make a normal call but can't answer it normally (including beep). The following situations are not excluded:

1 The mobile phone has a number interception function, which intercepts normal incoming calls by mistake. It is recommended to check your mobile phone.

2. The mobile phone or mobile phone card is broken, and it is recommended to change the card for testing;

3. The number setting is incorrect. The call was transferred to another number. It is recommended to cancel call forwarding or reset.

4 the local signal is unstable and there is a problem with outgoing calls. It is recommended to try again in another location.

If the above reasons are not solved, it is suggested that you can contact the local Unicom customer service for handling.

2. If your mobile phone can't send short messages, you can try to restart or change your mobile phone for testing to see if 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. 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;

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

5 SMS sending time exceeds 24 hours;

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

7 blacklisted by SMS;

The balance of number 8 is insufficient;

9 SMS Inbox and Outbox are full.

If the above reasons cannot be solved, you can contact the local manual customer service or go to the business hall to confirm whether the SMS function is enabled and hand it over to the staff.
