Openline works fully on iOS 26, the current major release, with expanded eSIM slot capacity and refined Data Roaming controls per line. Everything in our standard install and activation flow behaves as documented — QR scan or tap-to-install, Data Roaming toggle on the Openline line, Cellular Data set to Openline while abroad.

What's specific about iOS 26

  • The Cellular Settings pane looks slightly different from earlier iOS, but the labels stay the same: Cellular Data, Default Voice Line, and Data Roaming are all where you expect them.
  • Dual-line handling is more forgiving on iOS 26: if your home line loses signal for a moment, iOS keeps data flowing on the Openline line without a manual switch.
  • If you notice any regression specific to iOS 26, tell us the device model and the exact iOS build number — we escalate directly to our RSP partner for firmware-level triage.

Quick tips

  • Update to the latest patch of iOS 26 before travelling: cellular subsystems get quiet fixes on nearly every minor release.
  • If you rely on Wi-Fi calling on your home line, re-toggle it after any iOS update — the carrier registration sometimes drops silently.

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.
