Redmi 1s can't send short messages.

Because the right network operator was not selected, the mobile phone card used on Redmi Mobile Phone No.2 is different from the mobile phone card operator currently used. For example, the mobile card was used before, and now it is changed to Unicom card, which will lead to this phenomenon. The solution is as follows:

1, enter the red rice mobile phone settings page.

2. Click on "Mobile Network".

3. Click "Select Operator" to select the operator to which Card 2 belongs.

4. Click Back.
