Xiaomi 4miui6 can't send and receive text messages.

Xiaomi SMS can be received or sent, or the solution is as follows:

1. Check whether the center number is wrong and enter the engineering mode:

Enter: * # * # 4636 # * * in the dialing interface, and then select the mobile phone information in the pop-up interface. There is a box below the right side of SMSC, which is used to set the number of SMS center. After entering the SMS center number in the box, click Update.

2. Check whether there is software installed in the mobile phone that can prohibit the program from starting, such as some optimization masters or 360, whether there is an information program that prohibits the program from starting, and if so, allow the SMS program to start itself.

3. Try to install a third-party SMS software (such as GO SMS). If the third-party software can send and receive messages normally, clear the SMS data (Method: Settings-Program-Program Management-All-Information-Clear Data).
