Do you want to replace your older iPhone with a new iPhone? Here are some general instructions for accomplishing this task. Please be aware that this article provides a general description of the process, but not precise, step-by-step instructions. I don’t provide these because there are a number of variations depending upon exactly which model iPhone you currently have, which model you buy and if you’re also switching cell phone carriers. Before you start the migration or even buy your new iPhone, make sure you backup your iPhone. I recommend backing up your iPhone to both iCloud and to iTunes on your Mac. Next, buy the new iPhone. To migrate, two tasks need to be done.
- Transfer phone service from the old iPhone’s SIM to the new iPhone’ SIM.
- Transfer the backup of your previous iPhone onto the new iPhone.
[Update 2023: Most users won’t need to move their SIM card any longer. For a handful of years, iPhones have had support both SIM cards and eSIMs, which are embedded SIMs built-into the iPhone. Apple switched to using the eSIM by default, starting with the introduction of the iPhone 14 in 2022, if I recall correctly. Check out this newer article about things to keep in mind when migrating to a new iPhone.
