SIM Swap process

Swapping your physical SIM to an eSIM, or from eSIM to eSIM

You can complete Pay Monthly physical SIM to eSIM, or eSIM to eSIM change in our stores or by calling or messaging Spark. You must be in New Zealand to complete this change.

In store

When visiting a store, make sure you have a valid form of photo ID such as a NZ driver licence or passport from any country ready. One of our team will be able to walk you through the steps.

Calling or messaging Spark

You'll need to be in New Zealand and we'll verify we're speaking with the account holder. This will involve using our ID checker, so you'll need have a camera phone and a valid form of photo ID (a NZ driver licence or passport from any country) ready. From there our advisors will guide you through the process.

An approved authority can also arrange the SIM swap. For safety, the account holder will still need to be in New Zealand and verify their identity using our ID checker. You should let them know to watch out for a text from Spark and have their passport or NZ driver licence ready.

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.
