Just an FYI, on VZW, if you are off contract, on a MORE Everything plan, and you'd like to keep your current device, you can get a $25 discount per line (this is the EDGE discount without getting on the EDGE plan.)
It is called the Month-to-Month MORE Everything Promotion. You can access it by Changing Features on the My Verizon website (not the My Verizon phone app). Opt in and you should get an email.
I've never been on an Edge plan. 3 of 5 lines on my 10GB data plan just finished the contract and those three lines just had the promotion activated for a savings of $75/month without the need to buy or finance new phones. In another year, my bill end up being (80+15x5) $155 before taxes and my employee discount which is quite a good deal (I know Verizon and good deal rarely goes hand in hand)
Verizon feeling pressure from the competition... Customers benefit! (Don't ask about this in stores as they will deny that anything like this exists. They tried to convince me the only options were the traditional 2 year contract, financing phones on EDGE, or paying full price monthly without a contract)
