When ordering a new iPhone and initating a trade-in, do I must trade-in the device that is currently active on the line/account, or can I trade-in a device that is not currently active under Verizon service.
Iin other words, we want to upgrade from iPhone 12 Pro to 15, but instead of trading-in the iPhone 12 Pro, we want to trade-in iPhone 11 Pro that is used by someone else under a different carrier. Thanks
