well the number to the box would be like a mobile to mobile....but using the box would be .02 every call in the US of course.
It still might be cheaper...example 1000min x .02= $20.00
I think...you need a $40.00 above plan for free fav5 or else it is $5.00
So lets say..it is total...60 plus 10 for taxes more or less 70 which is way cheaper then the 120.
Here is the price plans for Sprint..like always going to a very limited plan..will make you also have limited to no options unless you add them.
