What is the reason why Xiaomi 8 can't send short messages? ?

There are three main reasons why mobile phones cannot send text messages. The first is that there is no signal, the second is that the mobile phone is in arrears, and the third is that the number of the SMS center is set incorrectly. Here are some solutions.

1. Unlock Xiaomi 8 version first: MIUI 10.3.5. If the cell phone doesn't have a signal, move to a place with a good signal and you can send text messages.

2. You can't send short messages when the number of the short message center is set incorrectly. If it is solved, click to enter SMS.

3. Then enter the settings page and find the advanced settings.

4. Then you can see the number of the SMS center and click Enter.

5. Then here, just enter the correct SMS center number. As the picture shows, different operators have different SMS center numbers.
