All three U.S. carriers that offer the iPad and iPad mini--AT&T, Sprint, and Verizon--support the 3G and 4G LTE wireless models that allow users to get online anywhere there's a signal (Sprint was a little late to the game, only beginning to offer service in Nov. 2012). All three carriers offer higher-end, multi-gigabyte plans, while AT&T and Sprint both offer lower-cost plans that include less data.
Note: iPad 3G contracts in place before 6/7/10 can retain AT&T's original $30/month for unlimited data plan.
