The ICCID is a 19–20 digit identifier for a specific SIM profile. It's how we identify your specific eSIM in support. You can find it on iPhone under Settings → General → About → scroll to the ICCID for that line.

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.
