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. If you still can't solve the problem, please look down.
