Mobile data hotspots aren't the world's most exciting products, though if you travel consistently, they can be an absolute lifesaver. But let's be brutally honest: the average mobile data consumer really doesn't care about the hotspot itself - as long as it works. They care about the network, and the monthly pricing. That's really it.
The hotspot is basically just a tiny little Wi-Fi router with a cellular modem and a lithium-ion battery inside. If it functions properly, you only remember it exists when the battery dies. If it doesn't, it's the worst thing in the universe, and you actively contemplate just how many pieces it would shatter into after a fall from the 4th story window of Homewood Suites.
