Hi guys, I purchased the new iphone 6 contract free at&t device and it appears not to work in Europe (Poland). I didn't have a nano sim card for my carrier in the US, but I checked and it worked perfectly fine with t-mobile. I restarted the phone, restored it and it still says "no service". Doos any of you know what to do in this situation? I was told every iphone paid in full will work internationally and I'm clueless at this point. I wanted to request a device unlock via AT&T, but on their website you need to provide data like a social security number, which I obviously do not have, since I'm not American.
