My phone number is Nokia 6 120ci. I can receive normal text messages, but 10086 can't. How can we avoid things happening? willies

This problem is very common. Say it again.

Turn on the phone and press the * key at the moment when the classic picture of Nokia holding hands with big hands appears, so that the phone will only start Nokia's own programs, and will not start any third-party programs, and then you can see whether sending and receiving SMS is normal. If so,

Obviously, it is a problem with third-party software or plug-ins (ask 10086mm if it is abnormal).

Then you start the software one by one (focusing on communication management software) to see who caused the problem.

Delete this software when you find it.
