Trade in
I have a iPhone 13 mini and I was wondering what the cost would be to upgrade to a bigger size
Question marked as
Have you simply tried going trough the online Apple Store's purchasing a new iPhone process? One of the first steps will ask you if you have an iPhone to trade in. Answering a few questions results in a pre-evaluation trade-in value.
Alternately, you can visit your local Apple Store, and have them evaluate your current phone there.
