Why did the mobile phone fail to send the total information?

In this case, if you are sure that the SMS center number is correct, there are several ways to check:

1, you can check whether the information sending report of the mobile phone is on, and set this function to off.

2. If it is caused by sending a certain amount of short messages, it is generally because the short message function in the operator's office is limited. You can call the corresponding customer service to explain the situation and then cancel it, and then you can resume. (But only if mass messaging is not spam).

3. You can ask people around you whether the short message is normal or not, and eliminate the influence caused by regional network failure.

4. Delete some short messages in the mobile phone to prevent the mobile phone from being sent because the memory is full. (including Outbox and Inbox).

5. Restart the mobile phone, and then exchange mobile phone card tests with friends.

First, the SIM card problem.

It will be abnormal if the mobile phone is in arrears or the SIM card is abnormal. You can try reinstalling the SIM card or replacing the SIM card.

Second, the SMS center number is abnormal.

Usually, the number of SMS center is different according to the attribution of our mobile phone number. Only when the SMS center is set up correctly can we send SMS normally.

If the setting of the SMS center is different from the number attribution (for example, the number of city A, and the SMS center is set to the number of city B), you can only receive SMS, but not send it.
