Within a few minutes, the mobile phone kept receiving text messages with different codes.

This is not very helpless, I met it a few days ago.

First, if you don't need this tired SMS service. You can call the customer 10086 to stop this service, and messages like 106 will not be sent to your mobile phone.

Second, if you have this service, you can install a software that can only be intercepted, and recommend 360 mobile phone software.
