Depends on the venue. Trade-show and conference Wi-Fi is often heavily managed and can block eSIM installs. Same rule as elsewhere: try, and if it fails, tether from another phone or wait.

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.
