If your home carrier is EU-based and Croatia is an EU/EEA member, you're already inside Roam-Like-At-Home and don't need Openline for data. Everywhere else, Openline is almost always dramatically cheaper. In Croatia, A1 Croatia and Hrvatski Telekom both carry us; 5G in Zagreb, Split, Dubrovnik and the Adriatic coastal cities.

Rough comparison

  • US/UK/AU home carriers charging daily-pass roaming typically cost $10–15/day — Openline plans in Croatia start at a fraction of that.
  • EU home carriers outside the EU zone typically fall back to per-MB pricing that can hit €10+/MB — Openline avoids all of it.
  • Chinese, Indian, and Latin American home carriers vary widely; even so, an Openline plan is usually cheaper and doesn't require you to opt in to a roaming pack at home.

Openline runs alongside your home line — you keep your number for SMS/2FA and use Openline for data.

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.
