And here is my framily ID
You also have to sign up in store! My local sprint store honored the promotion even though I signed-up for the framily plan on the phone. Not sure if this is possible in all areas because the add specifically states "when you visit a sprint store."
Sprint is offering a free Samsung Galaxy Tab 3 7.0 if you join the framily plan. You have to sign up for a $15 a month 2gb data plan for 3 months and you can downgrade to $5 a month 1gb data plan and sign up for a 2 year agreement. That works out to be about $150 in total cost, about the going price right now and if you buy a new tablet you can always transfer data service. Personally I think this is a reasonable deal.
