What makes a good Croatia eSIM?
- Plan size: Pick by how much you'll use, not just the days. For a typical week, light use (about 1.8 GB in all) suits 3 GB for 15 days, standard use (about 4.9 GB in all) suits 5 GB for 30 days, and heavy use (about 12.6 GB in all) suits 2 GB a day for 7 days. Check how much data you need.
- Speed after your daily allowance: Once a daily allowance is used up, speed drops to 512 Kbps. Every eSIMology plan prints that speed. Heavy users who need more each day can choose eSIMology's daily allowances, up to 10 GB a day, or a bigger fixed plan.
- Where data goes: Your data reaches the internet through a route in France, the Netherlands or the United Kingdom.
- Top-ups: Most plans can be topped up. You check data left on a web page, with no app to install.
Fixed GB, daily or unlimited: which Croatia eSIM fits your trip?

- A week across Split and Hvar: Standard use (about 4.9 GB in all) suits 5 GB for 30 days, and light use suits 3 GB for 15 days. Uber and Bolt for rides, WhatsApp and Viber for messages.
- Two weeks in Zagreb and Plitvice Lakes: Standard use (about 9.8 GB in all) suits 10 GB for 30 days. Light use suits 5 GB for 30 days. Most plans can be topped up if you need more.
- A month of heavy use: Heavy use (about 54 GB in all) suits 2 GB a day for 30 days. Heavy users can also take eSIMology's 20 GB for 30 days or a daily allowance up to 10 GB a day.
