Authentication & Plan Errors

PDP Authentication Failure

The "PDP Authentication Failure" error often indicates a problem with the connection between your device and the mobile network. It's related to how your device is authenticating and establishing a data connection. Here's how to troubleshoot:

1. Verify eSIM Activation

Ensure that your Gohub eSIM is properly activated according to the instructions provided. Double-check that you've completed all necessary steps.

2. Check APN Settings (Android)

If you're using an Android device, incorrect Access Point Name (APN) settings can cause this error. Go to your device's mobile network settings and verify that the APN settings are correct. Gohub should provide the correct APN settings for their eSIMs on their website or in the eSIM instructions. If the APN settings are incorrect, update them with the correct values.

3. Toggle Airplane Mode

Turn on Airplane Mode for 30 seconds, then turn it off. This can refresh your device's network connections.

4. Restart Your Device

Restart your phone or tablet. This can often resolve temporary software glitches.

5. Check Network Coverage

Ensure you are in an area with good network coverage.

6. Contact Gohub Support

If you've tried these steps and the error persists, it is crucial to contact Gohub support immediately. This error can sometimes be related to network provider issues or specific eSIM configuration problems that Gohub support can diagnose and resolve. Provide Gohub support with details about your device and eSIM plan when contacting them.

I'm experiencing the “This code is no longer valid” error. What can I do?

The “This code is no longer valid” error typically occurs during the eSIM installation or activation process and indicates a problem with the activation code or QR code. Here's how to troubleshoot:

1. Double-Check the Code or QR Code
  • Validity: Ensure the QR code or activation code you are using is the correct one and has not expired.

  • Accuracy: If you are entering a code manually, carefully check for typos, extra spaces, or incorrect capitalization.

  • Gohub should provide clear instructions on how to obtain a valid QR code or activation code, and what to do if the original one is lost or invalid.

2. Contact Gohub Support

This error is almost always related to the eSIM profile or activation code provided by Gohub. Contact Gohub support as soon as possible. They can:

  • Verify the validity of your eSIM profile or activation code.

  • Provide you with a new QR code or activation code if necessary.

  • Investigate any account-specific issues that might be causing the error.

3. Important Notes
  • eSIM Profile Management: Avoid deleting or making changes to your eSIM profiles unless instructed to do so by Gohub support.

  • Gohub Support is Key: For these specific errors, Gohub's support team is the primary resource for resolution.

By providing these detailed and Gohub-specific troubleshooting steps, you can help users effectively address these errors and ensure a smoother eSIM experience.
