Incomplete transfer of data from old iPhone to new iPhone
Bought new iPhone - 14 plus from new mobile network provider. Transferred most data from old iPhone to new but it was incomplete and didn’t fully transfer, so I cannot erase and resell. Now, I’m worried if I put new sim from new provider in old phone it will erase everything on new phone? Don’t have old sim for old phone? HELP
iPhone 14 Plus, iOS 17
