Hello good day! I want to know if they will give me a refund for my old iPhone.

You would get an in store credit gift card if you don’t apply the amount toward a trade in.

The settlement is for US customers only.

Refund or credit for your "old iPhone", Katyamurka?

You can get up to $70 as a trade in. See here! https://www.apple.com/shop/trade-in
