The best-practice pre-travel checklist:

Before you leave

  1. Buy your plan at home on your own broadband. Redeem the purchase code via app, web, or openline.com/start.
  2. Install the eSIM at home. The profile sits dormant and won't consume data or start the plan window until you activate abroad.
  3. Confirm the line exists: Settings → Cellular → you should see an "Openline" line (even if turned off).
  4. Test that Data Roaming is ready to go: tap the Openline line and confirm the Data Roaming toggle is present (you'll turn it ON abroad).
  5. Note your ICCID just in case (Settings → Cellular → Openline → ICCID).

On the plane

  • Airplane mode is on. Nothing to do.

When you land

  1. Turn airplane mode off.
  2. Toggle Data Roaming ON for the Openline line if not already.
  3. Wait 30–90 seconds for automatic registration.

That's it. Total abroad-setup time: 30 seconds.

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.
