Enter the new slimness. The cellular-capable version of the iPad Air, like the forthcoming iPad mini with Retina display, actually ships in only one flavor: universal LTE. All the US carriers, major and minor (Bluegrass? Aio?) support wireless on the device, and it ships unlocked. Is it, you might wonder, possible to do a bit of gaming the system with nano SIM swaps and network shopping? Specifically, can you take an iPad bought under the banner of the "other 3" US carriers (VZW, AT&T or Sprint) but pop in and use a T-Mobile SIM with its 200 MB of free-for-life monthly data?
As Coldewey points out, plenty of iPad Air buyers may have gone with their primary carrier of choice for their new purchase, but may not intend to spin up data service soon or have it running most of the time. By picking up a T-Mobile SIM card -- you might get one for free, bring your iPad to your local T-Mobile outlet and see what they say -- it's simple to maintain a free account that credits you 200 MB of service for emergency or extremely light data use. Then, for those times when you want the primary network engaged, pop the old SIM back in and roll on.
