Why can't I send text messages on the Xiaomi mobile phone I just bought? Urgent!

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 can't solve the problem, please look down.

2. Check whether there is any software installed in the mobile phone that can prohibit the program from booting, such as some optimization masters or 360, and whether the information program is prohibited from booting. If you still haven't solved the problem, 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).

In this case, the number of the mobile phone center is missing, or there is no signal on the mobile phone. The specific treatment method is as follows:

1. First, you need to turn on your mobile phone, and then enter a text message.

2. Press and hold the menu key to enter the advanced SMS settings, find the center number and check whether it is lost. If missing, contact the operator to consult the service number and complete it.

3. If the center number is complete, it is caused by the system problem of the mobile phone or the signal of the mobile phone.

Remarks: It is also possible that the short message cannot be sent due to the arrears of the mobile phone.
