How to block 8 17303 1 1 SMS?

Open the SMS Settings menu in the SMS list interface, set the rejection option, and change the SMS settings.

How to set the blacklist of SMS:

G mobile phone: Settings-incoming call/SMS interception-SMS interception-interception of registered numbers and phrases-SMS interception list (or enter Message-Menu-Settings-Spam settings-Spam filtering check-Spam string/Spam number-menu key-Create/Delete).

C-Net Mobile Phone (Telecom Edition): Application -VIP Mode-Mode-Information Restriction-Blacklist Rejection-Information Blacklist-Blacklist Number (SMS of some models and blacklist of incoming calls need to be set together).

One is that antivirus software sets interception, which can directly delete the intercepted numbers on the interception blacklist. The other is to set SMS rejection in the SMS function of the mobile phone itself. In this way, you can open the SMS settings menu in the SMS list interface and set the rejection option to change the SMS settings. Different mobile phone options will have different names, but the meaning should be the same.
