A guide to eSIM

An eSIM is an embedded SIM built into capable devices, enabling you to download a digital eSIM and connect to Optus without a physical SIM card.

When signing up to a new service or purchasing a new eSIM capable device, you're given the option to have an eSIM for faster activation and a more seamless experience. 

Some devices support dual SIM capabilities which allows you to have up to two numbers active on the same phone, at the same time.

Check with your mobile device's manufacturer to determine if it's compatible with eSIM.

Note.

  • Alternatively, you can order an eSIM
  • For Prepaid services, see Getting started with Optus Prepaid eSIM


Before you begin

Before you begin the eSIM process, make sure you have:

  1. A stable internet connection
  2. The compatible device you wish to activate your eSIM on
  3. The latest My Optus app version installed on your device
  4. Checked for a software update for your device (or the download may fail)

Alternatively, you can order a new eSIM. Please visit a store or contact us.

If you've lost your device, please get in touch with us as soon as possible so we can put the appropriate temporary restrictions on your service.

If you lose your Optus eSIM card before activating please get in touch with us as soon as possible, you'll need to go into a store and we'll issue a new Optus eSIM card with QR code to scan.

Otherwise if you don't wish to go into a store, you can contact us to get a Digital eSIM issued to you.

Please be aware that your eSIM may take 15 mins to 4 hours to connect.

If you've downloaded your eSIM, and are experiencing issues connecting to your Optus network, you can try the following:

  • Switch airplane mode on and off
  • If it's still not working, try turning off and on your device
  • If it's still not working, remove the physical SIM from your device (if you've transferred over from one)
  • Change your eSIM profile as primary service in your device settings
  • If you are still having issues, contact us

Firstly, make sure you have a stable WiFi connection during the entire process when downloading eSIM. If your connection drops in and out, that can contribute to eSIM download error. Also make sure the software on your phone is up to date.


If you think there's an issue, you can try to move closer to the modem / router, or find a more stable WiFi connection.

If you still have issues, contact us.

If you're the account holder, you may need to download an eSIM for another service holder or family member.

If you have Third Party Authority on the account, you'll have access to this feature using your My Optus app login.

For service holders without authority, you're not able to use the eSIM Transfer or Restore feature. The account holder will need to place an eSIM order for you.

You can't re-initiate the method. However you can go to My Optus App, under Account to set up your eSIM.
