I tried to use one for a month when I cancelled Comcast. They’re garbage. For home internet, you need it to always work. Having no internet is unacceptable, especially if you work from home. Well, the cellular hotspot services go back and forth between having signal and not having signal, so the internet is routinely not working.

They work in a pinch but never for normal everyday use

What's fun is that I don't even get the throttled speed before hitting my cap, but if I go over due to however they actually throttle it my Internet becomes useless.
