Sprint Drive is free for a limited time when you buy it on a 24 months installment and subscribe to a new line of service on Sprint. They will send you $5 credits per month over a period of 24 months so that you pay $0/month for the device. You’ll see the credits in your account within 2 billing cycles. They will charge you an early termination fee if you change your mind and cancel the monthly installment; and you will also be responsible for the remaining balance. Tax charges must be settled at the time you make the purchase for the car device.
