The ICCID is the eSIM's serial number. Contact support may ask for it.
iPhone: Settings → Cellular → tap Openline line → scroll down to ICCID (19–20 digits). Android: Settings → About phone → SIM status → tap the Openline SIM slot → ICCID.
Do not share your ICCID publicly — it's a semi-sensitive identifier. Only share it with Openline support via ask@openline.com.

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.
