170 SMS Center

Hello. I suggest you enter * # * # 4636 # * * to enter the system, and then select "Mobile Information". Set SMSC (short message center number) in the telephone information, enter the number of your local Unicom's short message service center there, and then select Save and exit. Call 100 10 for manual inquiry at the number of SMS service center.

If it can't be solved, it may be because the sim card is worn that the mobile phone can't read the information in the sim card normally. You can bring the owner's ID card to the business hall to change a sim card.
