$500 via Verizon e-gift card (sent w/in 8 wks). Activation of 4G LTE/5G phone on One Unlimited for iPhone (all lines on account req'd on plan), 5G Do More, 5G Play More or 5G Get More plans req'd. Device must remain active for 45 days. $500 charge back if service cancelled w/in 12 mos or eligibility req's are no longer met. See vzw.com/bring-your-own-device for details.
I'm turning in my note 9 and one of the steps is "Prepare your device for trade-in by disabling any activation locks, such as Find My iPhone or Google account. Disabling the activation locks on your old device will ensure you don’t lose your trade-in value."
