Why can't k6 activate SMS synchronization?

The reasons are:

1. The SIM card of the mobile phone has not been activated for SMS synchronization, and the operator has activated it.

2. The k6 mobile phone has not been upgraded to the latest version. Try to update the system.

3. SMS synchronization requires additional permission, so make sure that the corresponding permission has been turned on.
