Q: Why can I receive or send short messages on my mobile phone?

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.
