It depends on where you are. You can get a usable cell signal most places, except very remote, low population areas or up in canyons. The bigger question is how many people are trying to use the bandwidth at once. I've had nice, fast internet connections in the boonies because there are few, if any, others using it. And I've had horrible, almost useless connections in cities because even though there are more cell towers, there are lots of people using them at the same time. I've been places where the connection was nearly useless around breakfast time and after dinner, because those are the high traffic periods. I've been places where the cell signal seems to disappear sundown to sunset. I've been places along the border where the Telcel signal from Mexico overpowers US carriers. I've been in places where moving a few hundred yards made all the difference because a mountain had been blocking the tower. I've been places where you can pick up only one carrier and it wasn't the one I had. That said, there are many many (thousands? tens of thousands?) nomads who work online. It could work for you.
