My fiancé is currently on her parents' AT&T family plan with a 3GS and contact end date of February 2013. I am looking to move her to an open line on my Verizon family plan. My question is will AT&T allow us to just knock her line on the family plan to a $9.99/month basic phone fee, in order for the line to remain open? We have an old basic phone to use. Essentially, my question comes down to whether AT&T let's users on contract who are paying for monthly data on a smartphone take away the monthly data charge and move to a basic phone? Will this action cause the contract to be renewed? Thanks.
