The savings difference depends on the plan. A lot of people like to go for the $30 a month TMo plan (100 mins, 5gb data). Buying off-contract plus $30 a month is MUCH cheaper than this deal, although the $30 plan is obviously designed more for people into data than minutes. If you need the minutes, and don't mind a contract, this is not a bad deal.
+1 not terrible but for most slickdealers it is. We have 4 lines and pay 100 a month after taxes w. unlim text/calls + limited data.
But if someone truly needs unlimited everything I guess this is a decent deal.
