What is DPROM? I've never heard of sending SMS without a number.

Alpha tags, incredibly common in Europe and there's no way to block them (from an user perspective at least; ISPs block if they contain reserved words). https://messagemedia.com/uk/blog/send-sms-from-a-name-rather...

If you mean Flash SMS https://help.seven.io/en/flash-sms there are instructions online on how to disable them. Or do you mean normal SMS messages?

I meant normal SMS.

First time I've heard "DPROM", I think you mean AO-MT or just, coloquially, robotexts. Depending on the local law spammers can replace source phone number with a custom string.

On Android you can probably change the messaging app to a custom one, and filter messages there.

DPROM is just a something I made up for example, what I meant was receiving marketing SMS without a number to block ex: instead of 124 sender have ABC which cannot be blocked.

Move to the US or some other country that doesn't allow Alphanumeric sender ids? Or ask your carrier for help?

DPROM (Drug promotions portal) is an application that is designed to automate the drug promotions and vetting process.
