OAuth Login

OAuth method requires obtaining the callback URL. For instructions on how to get it, please refer to the page instructions:

Get Callback URL Instructions

  1. First, open the login page for the giffgaff website on a new tab: https://www.giffgaff.com and log in.
  2. After logging in, switch back to the eSIM-Tools page (i.e., this page) and open the browser developer tools: press F12 or right-click and select “Inspect” to switch to the “Console” tab.
  3. Click the “Start OAuth Login” button at the bottom; once the new window opens, switch back to this page (the eSIM-Tools page).
  4. Look for the error message in the console: “Failed to launch ‘giffgaff://auth/callback/…’”. Copy the callback URL from that line.

Get Callback URL

  1. Enter the obtained callback URL into the corresponding input box on this page and click “Process Callback”

Enter Callback URL

Method 2: Fetch eSIM Directly (For New-Purchase Users)

⚠️ This feature could not be fully tested by the author due to eligibility constraints. If you encounter issues, please open the browser console (F12 → Console), copy the full log, and submit it via GitHub Issues.

If you have already paid £10 in the official Giffgaff app but did not receive an eSIM, use this method:

  1. Click the "Fetch eSIM directly" card
  2. Click the "Fetch my eSIM" button
  3. The system will fetch the existing eSIM on your account and generate a QR code
  4. If multiple downloadable eSIMs are found on your account, a selection list will appear — pick the one you need and click confirm

This method requires no SMS verification code and skips the reserveESim / swapSim flow — it directly retrieves the QR code.

Method 3: Manual Activation (Paused)

Manual activation has been paused by Giffgaff. Please use one of the methods above.

After successful exchange, you will be redirected to the fifth step showing QR code and LPA information:

eSIM Information eSIM Information 1

6. Use Native eSIM Phone to Complete Scanning

  1. Open your phone's Settings → Cellular / Mobile Network
  2. Select Add eSIM / Scan QR Code
  3. Scan the QR code displayed on the page
  4. Confirm installation and wait for eSIM activation to complete
  5. Once activated, you will see the new number in your cellular network settings
