Use eSIM Quick Transfer only when the carrier and both phones offer it. If the line cannot transfer, keep the old eSIM active and obtain the carrier's activation path; do not delete the working line as a troubleshooting step. First, confirm carrier support, Wi-Fi, both Apple Accounts, device unlock state and access to the old phone.

The five ways to move an eSIM and what happens to the old SIM
Apple lists five routes, and which one you get depends on your carrier and iOS.
- eSIM Quick Transfer
- Moves the SIM from the previous iPhone to the new one without contacting the carrier. It requires iOS 18.4 or later.
- Carrier activation
- The carrier digitally sends the eSIM and you activate it from a notification in Settings.
- QR code, app or link, manual entry
- Scan the carrier's QR code during or after setup, use the carrier's app or link, or enter the eSIM details manually in Settings.
- Requirements
- iPhone XS, XS Max, XR or later, a carrier that supports eSIM activation, and a Wi-Fi connection on the new iPhone.
- The old SIM
- When the plan on the new iPhone activates, it deactivates the previous SIM, and you may need to remove the physical SIM and restart the iPhone.
Stop boundary
When this stops being a self-service repair
- !If the plan does not activate after the transfer, contact your carrier rather than deleting the eSIM, because removing it can leave you without service.
