Questions on how to block certain (or all) SMS messages.
Blocking annoying SMS e.g. sent from unknown numbers which are not in your contact list (usually spam messages).
Most companies send SMS messages without sending their numbers, in order to prevent you from blocking their SMS messages. But you can e.g. contact your network service provider and activate the DND (Do-Not-Disturb) service to stop receiving these messages permanently. Other measures are also possible, and covered by this tag.
