What's the matter with Unicom card sending text messages all the time?

The reasons why you can't send short messages and how to deal with them;

1. There is a problem with the number setting of the SMS center. It is recommended to check whether the settings are correct.

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

3. The sending format is incorrect. If you send short messages to foreign users, you need to add the international access code and country code before the number, and then add the other party's number;

4. Check whether the SMS inbox and sending box are full;

5. Query whether the SMS function is turned on;

6. Check whether the signal at this position is normal. If the signal is weak or there is no service, there will also be cases where SMS cannot be sent.

If the above situation has not been solved, it is recommended to contact the local manual customer service for handling.
