My friend is looking into getting a mobile hotspot. The best deal seems to be Virgin's $40 a month unlimited plan http://www.virginmobileusa.com/mobile-broadband/. The coverage for that is Sprint. Can anyone tell me how is Sprint 3G coverage in the Northampton, Amherst, and Greenfield areas? Also, other suggestions for internet on the go? I see AT&T and Verizon both have similar plans, but without an unlimited data option. Or is there a way to do a tethering thing with a t-mobile android phone (that she already has) and a laptop? Thanks, Tamar
