So during Uncarrier 7.0 T-mobile announced an open enrollment for their Jump program as an incentive to get people to get a new phone compatible with their new WiFi calling and texting initiative. I chatted with a T-mobile rep asking about the limitations of this promotion. According to him there is nothing to prevent you from joining jump during this promotion and dropping it the next month. He also said that any money owed on a previous phone is dropped if you trade in your old phone. Unfortunately he said no older phones would be compatible with the new WiFi calling, even though it supported their previous WiFi calling system. So I thought about upgrading my Lumia 925 during this period, but their best Windows Phone currently is the Lumia 635. The rep had no info on any new phones coming out, so if your a Windows Phone user who is looking to take advantage of this promotion unless you want to go with the 635 or switch to iOS or Android you're out of luck. The promotion runs from Sept 18 - Oct 17.
