Why is my 6600 automatically deleted after receiving the SMS from 10086?

*#7370# I tried to format the phone, but it didn't work.

I'm in the same situation.

First, turn on the spam filtering function of antivirus software.

Second, the original downloaded charging content, such as software or theme, is a residual program left after the SMS function is automatically deleted.

Third, the mobile phone automatically turns on the default SMS filtering software function.

It is not easy to solve this problem. You'd better find a seller and let him handle it for you.
