Summary

Bug in early 18.1 releases caused some eSIMs to disappear after reboot. Update to 18.2 or later.

If activation fails on iOS 18.1

  1. Confirm you're on the latest iOS 18.1 point release.
  2. Check for carrier settings updates: Settings → General → About.
  3. Delete and reinstall the eSIM via openline.com → My Codes → Reinstall.
  4. If the reinstall also fails, reset network settings.

Still stuck?

Reach Openline support 24/7 through any of these channels:

When you write in, include your purchase code (the OL-… code we emailed you) and, if the eSIM is already installed, its ICCID (Settings → Cellular → tap the Openline line). That's enough for us to find your plan and diagnose without back-and-forth.
