transferring cellular from iphone 8 to iphone 15
my iphone 8 uses a physical sim and my iphone 15 only uses e sim, i tried doing a transfer through my old phone but it says i need to update my iphone 8 to the latest ios. I go to my iphone 8 and it says it’s already up to date on 16.7.2 since it doesn’t support ios 17. What should i do
iPhone 8, iOS 16
