Hi Bamafan21,
Thanks for reaching out to Apple Support Communities. It sounds like you're have a question about trade in and the iPhone Upgrade Program. We're happy to get you in the right direction to assist.
You can view details about the trade-in option here: Apple Trade In
Specifically the section in the FAQ that states:
- If you are not already participating in the iPhone Upgrade Program, you can trade in your eligible device at an Apple Store for credit toward your subsequent purchase as part of the iPhone Upgrade Program.
- If you are currently a member of the iPhone Upgrade Program and wish to remain in the program, please do not proceed with Apple Trade In. After you upgrade and receive your new iPhone, we’ll arrange for you to trade in your old one. If you do continue with Apple Trade In, you will be responsible for both your outstanding iPhone Upgrade Program loan and the purchase price of any new iPhone you purchase through Apple Trade In.
You can also view details about the iPhone Upgrade Program here: iPhone Upgrade Program and How to Upgrade
If you need further assistance, reach out to the sales support team directly: Contacting Apple
Cheers!
