Why can't I save my Unicom card information center number?

You enter * # * # 4636 # * * to enter the system, and then select "Mobile Information". Do you see any input enthusiasts in the drop-down box? Just enter the number of the local SMS service center of your Unicom card there, and the other numbers will remain unchanged, then select Save and exit. Call 100 10 for manual inquiry at the number of SMS service center.
