I purchased the AT&T model for full retail, and went online to AT&T support chat and had them unlock it. Works well with my Tmobile sim. I get same level of coverage in my area for literally half the cost. Happy camper over here, looking forward to seeing more 5s verizon models show up over the year. Gonna have to pick one up just in case.
Hi! Sorry about the off-topic, but did you buy the iPhone 5S without contract? I`m from Norway and I bought a iPhone 5S from Apple Store (AT&T) at full retail price and I want to get in contact with AT&T chat support to unlock my phone, but it seems that I have to be registered with an account, and to be registered I have to have a US phone number etc... Just wonder how to unlock my phone without having any active subscription(s) at AT&T.
