Does anybody know what the difference is between Verizon Wireless prepaid and the monthly plan is? Looking at having 2 lines it would be $110/month plus taxes for 8GB of shared data. Getting the prepaid cards at Walmart would get 7GB per phone for $50 each. I would get almost twice as much data for $10 less a month. Both have unlimited talk and text. Anyone know if there is a difference in service? I tried doing an online chat with Verizon, but they danced around the question.
