I don't even have Tmobile and they only said that Tmobile doesn't receive their texts, and then they said to call support for just make me lost my time, over a hour in hold for they said they'll call back but they don't. Horrible app, Horrible service and not only that it's a lot of people that they can't get their money. They just taking people money hostage, and don't do anything about it. If you're trying to use these, don't even bother, they really suck, it's the worst app ever -50/10
