Why can't my Xiaomi mobile phone receive text messages and phone calls?

(1) Check whether some software such as Optimizer or 360 is installed in the mobile phone, and whether the information program is prohibited from starting.

② Check whether the center number is wrong and enter the engineering mode: enter: * # * # 4636 # * * in the dialing interface? Then select the mobile phone information in the pop-up interface. There is an SMSC at the bottom and a box on the right, which is the number for setting the SMS center.

③ Put the mobile phone card on other mobile phones to test whether you can receive SMS.

(4) Check the settings to see if there are any settings related to SMS blocking.

How to detect whether you receive text messages and phone calls:

1 It is recommended that you click SMS-Menu-Settings-Advanced Settings-SMS Center Number to reset. I suggest you try to call a friend to see if you owe money. I suggest you try to see if other cards plugged into Xiaomi's mobile phone can be used normally. If it still can't be solved, please back up the data and enter the recovery to clear the cache, user data and all data. After entering the system, the data will not be recovered temporarily, and try to send SMS directly. If it still can't be solved, it is recommended to back up the data and try the latest development version.
