The SMS of Huawei p7 mobile phone shows that it has been sent, but the other party says it has not been received. What happened?

The reasons why the SMS was sent successfully but not received by the other party are as follows:

1. The receiver's memory is full, so just delete the redundant messages.

2. The receiver signal is poor, so it is recommended to send it to a place with good signal.

3. Congestion, packet loss or interconnection obstacles affect the processing of short message center.

4. SMS function is not enabled.
