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.<p>On Android you can probably change the messaging app to a custom one, and filter messages there.
If you mean Flash SMS <a href="https://help.seven.io/en/flash-sms" rel="nofollow">https://help.seven.io/en/flash-sms</a> there are instructions online on how to disable them. Or do you mean normal SMS messages?
