Summary

Introduced improved dual-eSIM switching. If your Openline line was auto-disabled after the update, re-enable it under Settings → Cellular.

If activation fails on iOS 18.4

  1. Confirm you're on the latest iOS 18.4 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.
