Who I have the same questioned this topic

When you are on the Verizon Plan, your line access is going to be $20.00 for any line that is in Device Payments or Not in a contract. If you still have lines that are on a contract, then you are going to be paying for that line $40.00. So you will have to mix and match those numbers to get your exact cost. Also, for the 2GB, that would only be for the phone that was added as a new line, or upgraded.
