I'm paying $120/month for 2 smart phone (1 contract/1 month to month) to share 1GB. Plus they charge another $15 for going over the data limit by a couple of MB. Verizon doesn't have a good plan for 2 people that don't use a lot of data. I'd pay less if I have two separate accounts.
TMobile doesn't charge overage, no contract, 2 phone lines at 1GB each is $80. and they will pay the ETF. Plus I get unlocked phones instead of Verizon branded phones. I just went on TMobile and worked out $115 a month for the service and two phones (iPhone 5C and Galaxy S4) and once the phones are paid off, it's $80 a month with no $15 charge for overage.
