Hello Macrumors friends! First off, I thought there used to be a carrier segment on the page. I can't seem to find it on the mobile website. Apologies if this is not in the appropriate section. I am trying to help the in laws and their two daughters shop for a new cell phone plan. They've decided on tmobile (apparently it's great in the Ventura county area and so they're going with them after years of Verizon now raising my father in laws rates since he has retired). The question isn't whether or not to do TMO, it's a question about plans. I recently read four lines for the price of three with 10gb data on each. This comes out to $120 before taxes. The two daughters would be the only ones getting phones. Here come the questions: JUMP PROGRAM Do they really allow three upgrades per year? This seems like a rental, which is fine ($15 a month for an iPhone 6 isn't bad), but if you decide to payoff the phone can you keep it? Or is it literally just a rental. DATA STASH Not that I expect this to be an issue at all, but the fine print says data stash is available on 3 and 5 gig plans. Are the 10gb plans excluded? I would think not, but what do I know? I haven't been a TMO customer really for nearly a decade. MUSIC STREAMING Again, with 10 gigs I don't expect issues, however, are there any limitations to streaming? I imagine the girls would use apple music and google music. Maybe pandora? Does this generally not take from your monthly alotment? LENGTH OF OFFER I couldn't see any place that mentioned how long this plan was valid. Since there are no contracts, the worry I guess would be that the price would change, and while I know most companies generally grandfather, this some firms isn't the case when getting a new device. The idea for them is saving money (they're frugal AF lol) and this seems to be the best deal on the market, even better than TMO's own plans with lesser data packages.
