Should you choose eSIM or a physical SIM?

An eSIM is a digital SIM downloaded to your phone, while a physical SIM is more broadly compatible and easier to move between devices. giffgaff charges the same for plans on either format.

  • check_circleChoose eSIM if your phone supports it, is network-unlocked and runs the latest giffgaff app.
  • check_circleChoose a physical SIM if you are unsure about compatibility or want a simple backup option.
  • check_circleLarkSim currently sells physical giffgaff SIMs. Existing members can still request an eSIM replacement in their own giffgaff app.

What you need before starting

  • check_circleAn eSIM-capable phone. Recent iPhones, selected Samsung Galaxy models and Google Pixels are common examples, but check your device maker's settings for the definitive answer.
  • check_circleA network-unlocked device.
  • check_circleA reliable internet connection, ideally Wi-Fi, to download the network profile.
  • check_circleThe latest giffgaff app on the exact device that will use the eSIM.

New to giffgaff: set up an eSIM in the app

  1. 1

    Install the giffgaff app

    Use the phone that will carry the eSIM and connect it to Wi-Fi or mobile data.
  2. 2

    Create and sign in to your own giffgaff account

    Follow the app prompts to set up the account and choose a plan or credit.
  3. 3

    Activate the eSIM in the app

    Follow the on-screen steps to download and install the eSIM profile. Do not switch to a QR-code flow.
  4. 4

    Wait for service and test it

    New members are normally activated after installation. If signal does not appear, restart the phone or toggle flight mode; in some cases activation can take up to 24 hours.

Already have a physical SIM? Switch to eSIM

  1. 1

    Sign in to the giffgaff app first

    Use the existing giffgaff account so that you do not start the replacement in the wrong account.
  2. 2

    Open the replacement flow

    In the app, go to Account > SIM > Replace my SIM > Switch to a new eSIM.
  3. 3

    Finish installation on the target phone

    Keep the connection stable and complete the prompts on the device that will use the eSIM.
  4. 4

    Confirm that the old SIM is inactive

    When the eSIM activates, the previous physical SIM stops working. Remove it or keep it aside to avoid confusion.

Follow the availability shown in the app. giffgaff says most switches complete within an hour, although busy periods can take longer.

Troubleshooting

  • check_circleNo eSIM option in the app: update the app and confirm that the device supports eSIM and is unlocked.
  • check_circleNo signal after installation: confirm the profile is installed, toggle flight mode or restart, then check for local network issues.
  • check_circlePreparing from mainland China: you can check your device, install the app and prepare stable internet, but do not assume UK service can always be completed before arrival. Follow the live status in the app.
  • check_circleDeleted the eSIM: do not repeatedly attempt to reinstall an old profile. Follow giffgaff's replacement or account-recovery steps.
