I would not hesitate to recommend Verizon’s 4G LTE network. It’s head-and-shoulders above Clear/Sprint WiMAX and will likely stay that way for a while thanks to their use of the 700MHz band. Verizon’s rapid network expansion and broad 3G network are reassuring enough to entice me into a 2-year contract. And the Novatel MiFi 4510l is a fairly solid device, though not perfect.
