Hi everyone. I have been using a no-frill T-Mobile prepaid dumb phone on their "pay as you go" plan and really want to get myself an iPhone. I am fine with T-Mobile and don't like any contracts, so I am looking at their $30 plan. I am wondering if any of you could answer my questions... I did check some threads on this forum and T-Mo's Q & A section, but seems like people say different things... No-contract iPhones are really expensive, so at this point I'd prefer to buy an unlocked iPhone 5 off craigslist and get a T-Mobile nano sim. If I do it, 1) Can I be on their $30/month plan? 2) Can I transfer my current phone #? Thank you for your time, and I'd appreciate your help!
