For what it is worth Millenicom has increased the Advanced plan from 10GB per month to 20GB per month for $59.99.
I have used Millenicom for several months now and am pleased with the service so far. The Advanced plan uses the Verizon 3G network and coverage has been excellent. I do use a Wilson Trucker Antenna which improves the signal. At home the Cradlepoint Router is used for the two computers and sometimes a third is thrown into the mix.
This is the link for Millenicom if you would like to check them out.
