I will be spending two weeks in the USA (I'm from Northern Ireland, UK) and it would be really good if I could get my iPhone up and running over there for calls and text (I'll use WiFi for data). I have been having a really confusing time on the T-Mobile.com site and I may have it wrong but I was looking at this: T-Mobile® Prepaid SIM Card Activation Kit + $30 Refill Card and that would cost a total of $36.99. (do I have to pay tax on top of that?) That would give me calls at 19¢/min. How much would texts cost? I can't seem to find that on the T-Mobile site. Is that what I'm looking for? Any help would be great!
