Network & Coverage

Stay connected across every corner of Croatia

Your eSIM connects to the local networks of Telemach and A1 — for fast, reliable 4G/5G from the old town walls of Dubrovnik to the Split Riviera and the islands of the Adriatic.

A1
Excellent high-speed coverage throughout Zagreb, Split and major tourist hubs — ideal for streaming and video calls.
Telemach
Strong, dependable speeds on your eSIM's local partner network.
Popular destinations covered
Dubrovnik Split Zagreb Hvar Zadar Rovinj Plitvice Lakes Šibenik Pula Korčula

From Dubrovnik's ancient walls and famous filming locations to Diocletian's Palace in Split, the cascading lakes of Plitvice and island-hopping around Hvar and Korčula, your unlimited data keeps maps, translation and ride-hailing apps running wherever Croatia takes you.

Will my Croatia eSIM work on the islands and along the coast?+
Yes. Your eSIM runs on Croatia's leading carriers, which provide solid 4G/5G across the Dalmatian coast and popular islands like Hvar, Korčula and Brač, including most towns and beaches. Signal may dip briefly on longer ferry crossings but reconnects automatically as you reach the next port.
Can I share my Croatia eSIM as a hotspot?+
Yes — tethering is fully supported, so you can share your unlimited connection with a laptop, tablet or a travel companion's phone — perfect for working from a Split café or keeping the group online on an island day trip. One thing worth knowing: hotspot traffic counts towards the same 5 GB daily full-speed allowance, and tablets or laptops get through it faster than a phone. If you plan to keep several devices online all day, one of our data packages with a fixed GB volume is usually the better fit.

Frequently asked questions

Everything you need to know about your Croatia eSIM

Is the data truly unlimited? +
Yes — there is no data cap and your connection is never switched off. Like every unlimited travel eSIM, the plan carries a daily full-speed allowance: in Croatia that is 5 GB per day. Beyond it you stay online at a reduced speed (512 kbps) for the rest of that day, and full speed returns automatically the next day. Hotspot traffic counts towards the same allowance. We publish the exact figure for all 175 destinations — see our daily allowance by country.
When does my eSIM activate? +
Your eSIM activates the moment you first connect in Croatia. Your days don't start until you're there — so you can install it weeks before travel with no waste.
Which devices are compatible? +
Any unlocked eSIM-compatible device: iPhone XS and later, Google Pixel 3+, Samsung Galaxy S21+, and most modern Android flagships. Check Settings → Cellular → Add eSIM to confirm.
How do I install the eSIM? +
After purchase, check your email for the QR code. On your phone: Settings → Cellular (or Mobile Data) → Add eSIM → Scan QR Code. It takes under 2 minutes. Full step-by-step instructions are included in the email.
What if I need help? +
Our team is available 24/7 via live chat at aerosims.com — day or night, before or during your trip.
Could my internet speed ever change? +
Yes — once you pass the daily full-speed allowance, which in Croatia is 5 GB per day. After that, data keeps working at a reduced speed (512 kbps) for the rest of that day and returns to full speed the next day. Nothing is cut off, and hotspot traffic counts towards the same allowance. This tier is set by the local operator, not by AeroSims. Full details for every destination: daily allowance by country. If you prefer a guaranteed volume at full speed, our data packages give you a fixed number of GB.
