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.
04/18/2012 - got a call from this number. I am in FL, I have family in MN and at first thought it was maybe someone there. Didn't answer it as I am at work and if it was family, they would leave a message. Sounds like it is spam. Glad I didn't answer. I also have TMobile, but not prepaid.
Got a call from this number today 4/18/2012 No message left on VM. I'm very selective on who I give my Cell # to so I don't know who this is or what it is about.
I got a call from this numbr too, I didn't answer. I recently switched from a contract to a pre-paid montly plan also with T-Mobile. Maybe Johnny is right and it has to be with T-Mobile not protecting our private information.
