I looked at it the other day, and you would just have to have service on both phones, even if an existing line. The free phone gets monthly bill credits to offset the payment (not including the initial sales tax). If you remove one from the line of service, then the bill credits end and you would be required to pay the remainder of the balance.Does anyone know how the Buy one, get one free with T-mobile works. It says you don' have to add a line (I already have two lines) but it's kind of confusing otherwise.
