I'm trying to set up a system where I have google voice and a data plan only. Currently trying out google voice + wifi which is working fine, but I sometimes do need coverage when I'm wifi inaccessible. Any insights on data only plans?
edit: oddly enough, another alternative is to sign up for one of those providers that have free wifi hotspots all across the city (e.g. CableWifi, XfinityWifi), which could be cheaper than a data plan
