When I first bought the m1i, I could receive messages from 10086, but one day I was using the mobile SMS business hall to check the preferential business package and suddenly I could not receive 100.

This has happened to my mobile phone before, that is, the information of 10086 flashes and then cannot be seen. At first I thought it was a virus in my phone, so I put someone else’s SIM card in my phone and it turned out to be normal. My SIM card was also normal when I put it in someone else’s phone. When I put the SIM card back in my phone, it was normal. When I used my phone, everything was normal. I still don’t understand what the cause was, but you can solve the problem using this method.
