There are a number of differences between the AT&T and Verizon models of the new iPad, but for those who do plenty of travelling around America, Verizon seems to be the way to go. Not only is Verizon's LTE network larger — it covers more than 200 million Americans compared to AT&T's 74 million — but the Verizon iPad can also run on AT&T's 3G network by popping in the appropriate micro-SIM card. A member of the MacRumors forums has confirmed this by using the card from an AT&T iPhone 4S in a Verizon iPad, which, with a few tweaks to the carrier settings, managed to run on the new network — though, because of some compatibility issues, the swap won't let you connect to AT&T's LTE network. Meanwhile, PCMag even managed to get the Verizon iPad working on T-Mobile using the same trick. Though, in that case the device was restricted to the 2G EDGE, resulting in less than optimal speeds. While the news isn't all that surprising, it's definitely useful, especially if you're stuck in an area with poor Verizon coverage. Now the question is where you're going to buy your new tablet to begin with.

If you happen to have an AT&T micro-SIM card laying around, you can use it in your new Verizon iPad to hop onto AT&T's 3G network.
