I have been received text messages from area code 570 (somewhere in Pennsylvania). I do not know anyone there.
It's a message that will just say "hi". I think they are trying to get me to respond. I've gone to the Verizon site and blocked the number.
Then another one will come up from a different number in the same area code. Anyone else having issues? Can they access my phone if I tell them to stop? Any other suggestions...? It's annoying and troublesome.
