The address has to match your credit card address. So no, it's not that easy. The only option is a prepaid Visa card bought in the US. For some reason, I find it hard to believe that AT&T is suddenly becoming more open to the rest of the world in its store with the new iPad than it ever was with on-device activation on the iPad 2. It doesn't make any sense.
Official rules and what stores will do are different especially stores in areas with heavy tourist traffic. I have bought prepaid SIM cards in Munich, Germany (o2) and Rome, Italy (TIM) with no problems or questions. Germany requires an address (they made one up, didn't even ask me they just did) and Italy requires a taxpayer ID (presumably also made up or generated). The US has no requirements so I'm sure AT&T stores have more leeway than their automated system. Just make sure that you visit a store that receives a lot of tourist traffic!
Has anyone tried it and been successful? With the iPad 2, I used my Canadian AmEx and had no trouble. Visa wouldn't work. They don't confirm the address with AmEx. It looks like it will be a lot harder without on-device activation.
First hand experience this week in Brooklyn with my Canadian iPad LTE/4g (3rd gen). Went into an AT&T company store (not an authorized reseller), was given a LTE micro-sim for free, was able toick a prepaid plan on device with a Wifi connection, paid with my Canadian American Express
Great, thanks for the update. I will try it next week when I'm in the US. In Canada, Bell no longer offers the on-device prepaid option for the LTE iPad, so based on eulacia's post, I assumed it was the same thing on AT&T, but that's great news. Prepaid is so much more convenient for travelling.
Yep, I just entered my info, and CC, and was done. But I live in the US if that matters any. My iPad is a AT&T LTE as well in case that wasn't mentioned.
