Not sure if this is the right forum to post this in so, Mods, feel free to move it if necessary. Contract is up. I'm eligible for an upgrade...or I can switch. I'm really kind of clueless about the LTE technology and the 3 different versions Apple is making for the various networks. Am I even phrasing this right? Basically, I travel a lot, a fair amount internationally. I really like being able to buy a local SIM card and get on with my trip. Aside from this nano-SIM thing and I've been buying my devices factory unlocked, am I not going to be able to do this anymore? Do I need to examine the cities I travel to most frequently and figure out what model/US carrier I need? Or does none of this matter and I am just a confused person? I'm currently w/ AT&T and have a grandfathered iPhone unlimited data plan. Service in Seattle & LA are pretty craptastic but GRANDFATHERED UNLIMITED DATA. Verizon seems to have much better reception there and here in NY but is the data faster? Now that the iP5 is LTE, are they all pretty close to same speeds? Obv iP5 is not out yet but generally speaking RE: LTE data speeds. I don't like these tiered data plans on Verizon. booo. But I am considering a hotspot so I guess those data plans are good if you have multiple devices? I LOVE my MBA but have run into places where there was no WiFi. For those who have switched or perhaps have personal experience with these questions, your advice is greatly appreciated. Again, sorry if this is in the wrong forum. And thank you.
