I see Verizon has prepaid mobile broadband -

day, week, month etc.
but you would need to verify with Verizon that your laptop will work with it or it you need to add anything.

[1Prepaid Mobile Broadband usage is not available on any PC cards. Only available on Express-Cards, USB modems, Intelligent Mobile Hotspots and Mobile Broadband Built-In on select notebooks/netbooks.]

So others might have it too -just search for" prepaid broadband" to find other carriers.

I buy the verizon pre paid service when I travel. that way I dont have to count on relatives that may or may not have it at their homes, or areas. You can buy month to month or a block of years.
