Yes, Zinia is fully compatible with trade-in services. If you find a merchant that offers a trade-in service and Zinia, you can trade in an eligible device to reduce the amount to be financed. The merchant will calculate your payment plan using an estimation of the value of your old device. If your device is finally valued higher or lower than expected, the merchant will automatically adjust your plan. Check the merchant's trade-in terms and conditions for further information.
