I share a data plan with my son. Inevitably he uses all the shared data and then I can't do work email. How do I limit the amount of the shared data available to him on his device?
Apparently the Family Base add-on (https://my.verizonwireless.com/vzw/nos/safeguards/SafeguardProductDetails.action?productName=familybase) from Verizon will allow you to set limits on how much data a particular device can consume. I think it is free for the first 3 months (not sure) after that it will cost $5 per month. I have heard rumors though that it does not work well with iPhones???
