On-device SIM transfer from one iPhone to another

Spark now supports the on-device transfer of eSIM from one iPhone to another iPhone. This is an easier way of transferring an eSIM without visiting a Spark Store.

You can do the transfer while setting up your new device for the first time or after you have finished setting it up.

The on-device journey uses both Apple's secure intent and Spark's added layers of security to mitigate any fraudulent activity.

Note: If you don't have access to your current iPhone, you will need to go into a Spark Store to request a SIM transfer.

Before you begin

  • Make sure that you have backed up your device.
  • Have your Apple ID and password ready.
  • Make sure you have a backup of your previous device.
  • If you have purchased a new device, you may be eligible for temporary iCloud storage.
  • Make sure your old and new device are updated to iOS 18 or later.

    Note
    : iOS 18 Beta version is not eligible.
  • Make sure that you're signed in with your Apple ID on both old and new devices, or make sure that your previous iPhone is unlocked, and nearby with Bluetooth turned on.
