Hi Everyone, Hoping somebody won't mind answering what are probably a couple of recurring questions here. I'm thinking of signing up for tmobile's prepaid service, specifically their $30 unlimited data / 100 minute plan, and I have my eye on the Galaxy S2. I see that Walmart sells this phone, packaged with a one-month card, for $330 which seems like a pretty good deal. Before I jump, though, I wanted to make sure I understand a few things. 1. Would this phone be the exact same S2 that I would get from Tmobile if I signed up for a 2 year contract, or is it crippled in some way? My concern is that, if I find that 100 min. is not enough, or I want to change to a family plan with my wife in the future, that the prepaid S2 wouldn't work in a "contract" situation. 2. My other question is whether anyone knows if, when purchasing one of these Walmart bundles, you have the opportunity to add services to the plan, or if you are locked in to what comes with the phone? I would be interested in adding the hotspot capability for an extra $15 per month, and just want to be sure that it is possible. Do you get an opportunity, when you are activating the phone maybe, to add this service? If anyone can shed some light, I would be most grateful Thanks in advance for your help.
