Back up your phone to a computer, then throw your phone away and port your # to a Virgin mobile smartphone. Measured voice, Unlimited text and data as low as $35/mo with no contract. $30/mo with direct CC billing. It uses the sprint network so you need to check coverage in your area. I am saving $120/mo for two phones after ditching Verizon. Better service and big savings.
