Hi

iPhone 15 pro

ios 26.5

Esim


Im currently abroad in Spain. My phone data has been working perfectly for 7 days but it’s just started showing pdp authentication failure. My sim has signal and voice works but mobile data fails with pdp authentication failure on all networks (orange, Movistar, Vodafone). I’ve reset network settings and manually tried all carriers. Please reset/re-provision my roaming data session

 

Thanks,

Ben

Hi ​@Ben137890

 

Thank you for reaching out, and we’re sorry to hear that you’re experiencing issues with mobile data while roaming in Spain. We understand how frustrating this must be, especially as your service was working previously without any issues.

 

Having reviewed your query, please note that roaming data issues can sometimes occur if account-level roaming settings or spend controls have been changed.

 

To help resolve this, please ensure the following:

1. Check roaming is enabled on your account and device

  • Open the iD Mobile app and confirm that roaming is switched ON
  • On your handset, ensure Data Roaming is also enabled:
    • Settings > Mobile Service > Data Roaming > ON

2. Set your Bill Cap to £0
To prevent any out-of-plan restrictions affecting roaming data, please ensure your Bill Cap is set to £0 in the iD Mobile app.

  • Open the iD Mobile app
  • Go to Settings / Billing
  • Select Bill Cap
  • Set it to £0

3. Restart your handset

  • Turn your phone off completely
  • Wait 2–3 minutes
  • Turn it back on and reconnect to a local network (Orange, Movistar, or Vodafone)

4. Manual network selection (if needed)

  • Go to Settings > Mobile Network
  • Turn Automatic OFF
  • Select a different available network
  • Wait a few minutes and test again

Once the above has been completed, your roaming data session should reconnect automatically.

 

If the issue continues after checking the above, please contact us via Live Chat or send us a direct message through our social media channels, and we’ll be happy to investigate this further for you.
