Tracfone or one of the similar ones is likely your best bet. AT & T has something similar called a Go Phone. Others likely do also. Some place like a Pilot or Flying J, Loves, any of the travel centers usually carry them + the cards for additional minutes. You can get something, think it's called a Hot Spot but not positive, for your laptop, but my understanding is that they're pretty pricey. Almost all McDonald's have free WiFi and more providers are popping up all the time. Some campgrounds have WiFi, either free or for something like $3 a day, but some of them don't work well. Some of the places we've stayed used TengoNet and it's a PITA. If you're just going to be doing a quick online check, you might be money ahead to just buy something like a Kindle with the 4G....connection wherever you have cell phone. If you haven't already checked with your current phone company, I would think a call to them to see what they might suggest would be a good start. Have a great trip!
