Why can’t my mobile phone receive text messages from China Unicom customer service?

If you cannot send and receive text messages, you can try to restart or change your phone for testing, and check whether the following conditions exist:

1. The SMS center number is set incorrectly;

2. There is no signal or the mobile phone battery is low;

3. The system is busy due to the peak SMS sending volume during holidays. It is recommended to try again later or avoid the peak sending period;

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

5. The mobile phone has blocked the text message sending function;

6. It is included in the text message blacklist;

7. The number balance is insufficient;

8. The SMS inbox and sending box are full.

If the above situation is not resolved and the problem remains unresolved, it is recommended that you contact the local manual customer service to handle it.
