Existing customer and we got the $200 smart phone trade in account credit on a new Turbo II and also got a $300 smart phone trade in account credit on a Maxx II phone new line activation at the same time in the Verizon Store.
Both trade in phones were in good shape and booted up so make sure you charge the phones you want to trade in before going to the store. They also took the backs off the old phones and scanned the bar codes in there to confirm something.
We had some really old smart phones to trade in so if you have the same situation, I would keep the newer unused smart phones you have so that you can use them as a WiFi only phone, when desired, to run your Chrome Cast or whatever at home.
Account rep said we should see the credits on the next billing statement.
