I bought a sim from a t-mo store and activated the 30 dollars monthly no contract and had to hustle for it cause tmo didn't want to do it cause supposedly I have to purchase the sim kit ($30 month no contract) from Walmart, but anyways they gave me the plan on the sim. Put it in the ipad mini (AT&T) and boom full bars and LTE even showed up on the top(in midtown NYC) I inputed the apn settings fast.t-mobile.com exited settings held the power and home button, ipad turned back on opened up safari typed in apple.com and it worked flawlessly ! Buuuuut 30 minutes or so later of browsing data stopped working and I was extremely pissed off after bragging about an mini on tmo to all my friends. Long story short..... Called tmobile and a rep from wherever the call centers are from these days told me she didn't have the settings for my apple device that I should call apple and tell them to help me with the device setting to make it work (huh?) I found that hilarious I hung up and I'll call back tomorrow during the daytime hours and see if I can get it back up and running. I had my share of trouble with tmobile in the past and got my way most of the time. I think there has to be a way for it to work on this 30$ a month prepaid unlimited text and web and 100 mins plan since it'll work on a "mobile broadband" plan from tmobile Sorry for the long post just my 2 cents if anyone has had luck in NYC or any other city using an ipad mini with tmobile on the prepaid unlimited web text and 100 minutes please give this community your input. There should be a sub forum for the ipad mini too if someone can do that it would be cool.
