Hi Guys, I have got an ATT droid smartphone and I went and got an Iphone 4s yesterday from an Apple Store. Paid for the no commitment version as I wanted it unlocked due to travelling a lot. To get my SIM card from my existing device I used the Noosey tool to convert my existing SIM card to a Micro SIM. When I put this into the device it works well but I get a message saying that I dont have a data plan, voice and messaging works fine. But when I put the card back into my existing device the data plan works. So do I have to get a special data plan from ATT to make this work on the Iphone? And if I do and call them will they give me a hard time for converting my own Sim card? Thanks!
