What is the best wireless provider?

I may be using the wrong term in the title. What I’m after is a service for my laptop that will work nationwide without having to be in a “hotspot”. We will be on the road for about a year and will need to have internet capability along with cell service. The latter doesn’t seem to be a problem to find. From the searching I’ve done, it appears that AT&T gets good reviews, but I’d like to see if there is any personal doper experience with this. Thanks.

Bump. Really? Nobody has ever used wireless service for their laptop?
