My wife and I have an old family plan (just minutes with data and text added). Our lines have separate contract dates...her line has the 2GB data...and mine the grandfathered Unlimited Data. What I am trying to find out is if her line signs a new contract for a subsidized phone...does it force both of us into the full new Share Everything plan (and hence me losing my unlimited...which I average 8-12GB of usage)??? Or can her line be somewhat separate still???
