If you regularly travel with devices needing Wi-Fi, get Verizon’s Jetpack MiFi 6620L. Its battery life is among the best we’ve seen in hotspots, it runs on the largest and fastest U.S. LTE network, and its pricing is competitive.
Just about every smartphone can act as a hotspot, sharing its connection over Wi-Fi with tablets or laptop and you might think that is enough. However, if you work on the road a lot, a hotspot offers a more reliable data connection than your phone and will run for much longer on a charge than a phone in tethering mode. Think two full days of work versus five hours.
