We spend most of the year migrating up and down the west coast from Baja to British Columbia, avoiding as many large cities as possible... kind of back road ramblers. I have been looking for a cell phone plan that would provide minimal, emergency type service in the Oregon, Calif., W. Arizona, Nevada chunk of the country. Lots of plans out there, but I can't find the single one that might suit our needs. Any tips or ideas anybody??
