Calls but only rings 3 times haven't caught it yet and they have been calling every other day if you call back it says the number is not in service but I think that is a fake recording because it only lists the last 7 of the number and real people I call who have had their phone disconnected it reads all 10 digits.
FYI, TMobile does not sell ANY information OR give it out. I know, I used to work there. Spammers get phone numbers the same way they get your email address. If they call you & you don't answer, it doesn't use your minutes.
