How to switch between iPhones?
I currently have a old UK sim in my iPhone 6S and my new SA sim in my old iPhone 5. I would like to be able to completely swap them over. Can I simply just back up each one onto iCloud and then wipe both phones to factory settings and reload each one individually? Or will each backup wipe the other?
Any info / clarification gratefully received!!!
iPhone 6s, iOS 10.2.1
