What if my Xiaomi mobile phone can't set the SMS center number? Xiaomi official website customer service said that inserting other mobile phone settings could not be set. What should I do?

Hello, you can modify it by going to SMS-Settings-Advanced Settings. If you plug in another mobile phone, you can't modify it. Maybe the card is locked. Please consult the operator.

If Xiaomi can't set it, I suggest you back up the data, restore and clear all the data (shut down, press and hold the volume up+power on button to resume), upgrade your mobile phone to the newly developed system with a line brush, and don't install the application that requires root permission for the time being to see if it can return to normal.

Thank you for your support and wish you a happy life!
