Can someone with experience using a cellular iPad overseas (preferably a 3rd Gen. AT&T LTE model) comment on how the international roaming works? There's a place on Apple's website where it says: "If you want a local connection when youre traveling, just pop in a local SIM card." Is that as easy as it sounds with a cellular iPad? Reason I ask - I'm getting an LTE iPad Mini (AT&T). I realize that it won't work with the LTE networks in Europe, but what can I expect as far as 3G service? Will I have to get a nano-SIM in the country I go to? What would the prices be like for "roaming" with AT&T's international 3G partners on a tablet? If you do get a local nano-SIM, do you have to jailbreak the iPad or is it SIM-unlocked? Thanks!
