I have been getting scammer texts from a supposed Harris Bank credit card account--which I never have had one so this is a scammer--for a few years now. This uses my minutes.
I am sick of it totally, so today I phoned TMobile regarding can they block them? They can and would on my pre-paid cell phone account. I called their regular 877/778-2106 number and kept saying "agent" when the recorded message came on and got thru right away.
They seemed happy and willing to do this, and the lady said she blocked ALL the scammers that were texting me as they have a listing of them, and to call them if I get more scammers texting me in the future
The reason I am posting this is that I'm assuming all the cell phone companies do this for their users. Had I had a clue that they would block these numbers with a simple phone call to them, I would have done this years ago. Hopefully, this helps someone else here.
