We went in today and bought the system, the person we dealt with when we first started talking said no way, no system like that exists. We said we saw it on a rv forum and they said it just came out, he went and searched on his tablet and then went and talked with another person and said something new i guess, yep we can sign you up. Seems to be working very well and it is $50 plus taxes and you have to have direct billing. We are not T-Mobile phone users, didn't seem to make any difference.
