Why can't Xiaomi 3 receive text messages?

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. If you still haven't solved the problem, please look down. 2. Check whether there is an optimizer or 360 software installed in the mobile phone, and whether the information program is prohibited from starting. If the problem is still unresolved, please continue reading. 3. Try to install a third-party SMS software (such as GO SMS). If the third-party software can send and receive normally, please clean up the SMS data (method: Settings-Program-Program Management-All-Information-Clear Data). If you still haven't solved the problem, please read on. Please try to install the SIM card on another mobile phone. If you can't send and receive, congratulations. You can go to the business hall to find customer service MM to chat for free. If you still can't solve it, you can ask Xiaomi online or the official forum.
