What should I do if the SMS function is turned off?

After the SMS function is turned off, dial 10086 directly and switch the manual service according to the prompt to reopen it, or reopen it in the local business hall.

The reasons why mobile phones can't send short messages are as follows:

1. No or wrong SMS center number is set, just reset it;

2. The signal is weak, there is no signal or the battery of the mobile phone is insufficient, resulting in the information not being sent normally;

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 and retention is valid for 24 hours;

5. Whether the SMS inbox and sending box are full;

6. I suggest you restart your mobile phone or change it for a test.

The simple processing method is as follows:

I suggest you change your mobile phone and see if you can send and receive short messages. If you can send and receive short messages, it is suggested to plug the card back into your mobile phone and send yourself a short message to see if you can receive it. If not, it is recommended to check whether it is a sim card problem; It is recommended to bring your mobile phone card to the local business hall for testing or replacement.

In addition to the above simple troubleshooting, it can't be solved. You can contact local manual customer service for handling.
