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.
