What to look for in a 4G mobile hotspot
I’ve spent most of the last decade using cellular routers as my sole connection for work. On trains I’ve stayed connected to the office while others crawled along on congested Wi-Fi. I’ve used mobile hotspots on all the major U.S. carriers, for video teleconferencing, building websites, and downloading a magazine’s worth of raw image files. In other words, I’ve put these devices through a lot and I rely on them heavily.
