Xiaomi's mobile phone 2S can't send short messages, how to solve it?

If your Xiaomi mobile phone 2S can receive short messages normally during use, but can't send short messages, you can try to solve the following problems:

1. Enter the SMS interface-Menu button-Settings-Advanced Settings-Set the SMS center number, for example, 86 13800000000 (the correct SMS center number needs to be consulted with the customer service of the operator of the network you are using, and the telecom version does not need to set the SMS center number);

2. Insert the mobile phone card into another mobile phone and set the SMS center number, and then try to insert it into your own mobile phone;

3. Check whether the management application installed in the mobile phone restricts sending short messages;

4. Upgrade the mobile phone to the latest version of the system.
