Charm Blue SMS reminder is not your SMS application. What should I do?

If the text message says "it's not your SMS application", I suggest you rule it out according to the following methods:

1. If you use a third-party SMS application, you can select "Default Message Application" in SMS settings.

Or select "System Default" in Settings-Application Management-Default Application-SMS.

2. If you enter the guest mode, you have no right to send and receive short messages in the guest mode;

You can enter a non-guest password, enter Settings-Security-Guest Mode-and check "You can make phone calls and send and receive short messages".
