The latest SMS of Huawei mobile phone is not on it. How to solve it?

There are two possibilities for slowness:

1, because your network signal is not good, there is a great chance that sending text messages in places with poor signal will be unsuccessful, and then the system will automatically retry, which looks very slow. When the number of retries exceeds the threshold set by the system, you will be prompted that sending failed;

2. It is rare that your system runs slowly. Generally, when the system is running slowly, it will only be slower to open the short message (program) and faster to send it.

So it's possible that your signal is bad. Please adopt it.
