Zagreb Split Rijeka Dubrovnik Zadar Osijek
Croatia has solid 4G/LTE coverage along the entire Adriatic coast and all tourist destinations. HT (Deutsche Telekom group) has the widest national footprint and best island coverage. A1 and Telemach are strong in Zagreb and major cities. Dubrovnik Old Town, Split's Diocletian Palace, Zadar, and Šibenik are fully covered. The islands — Hvar, Brač, Korčula, Vis, and Mljet — have 4G in main towns and harbours; remote beaches reached by boat or hiking may have weaker signal. Plitvice Lakes National Park has 4G at the entrance and main viewing platforms; some remote trail sections are 3G. The coastal highway (Jadranska Magistrala) has full 4G throughout. Island ferry crossings have coverage near ports.
Plan size
How much data do you need?
Pick your travel style and trip length — we'll suggest the right Croatia plan, no guessing.
Will this work on the islands — Hvar, Korčula, Vis?
Yes in main towns. Hvar Town, Stari Grad, and Jelsa (Hvar) all have 4G. Vis Town and Komiža (Vis) are covered. Remote beaches and hiking trails on the islands may have weaker signal.
Is Dubrovnik Old Town covered?
Yes. Dubrovnik has excellent 4G/5G throughout the Old Town, city walls, and cable car to Mount Srđ.
Does the eSIM work at Plitvice Lakes?
Yes at the park entrance areas and main viewpoints. Some remote trail sections between the upper and lower lakes may be 3G. Coverage is fine for navigation and photos.
How does pricing compare to Airalo Croatia?
Flysimio is typically 40–55% cheaper for equivalent Croatia plans on the same HT or A1 network.
Does this work in Slovenia or Montenegro too?
Your Croatia eSIM covers Croatia only. For the Piran, Ljubljana, or Kotor side of a multi-country Adriatic trip, buy separate eSIMs or a regional Europe plan.
What is an eSIM?
An eSIM (embedded SIM) is a digital SIM built into your phone. Instead of a physical card, you scan a QR code and your plan installs instantly — no SIM tray needed.
Is my phone eSIM-compatible?
iPhone XS (2018) and newer, most Android flagships from 2020+, and all Samsung Galaxy S21+ devices support eSIM. Check our compatibility page for the full device list.
How do I install the eSIM?
After purchase, we email a QR code. On iPhone: Settings → Cellular → Add eSIM → Scan QR Code. On Android: Settings → Network & Internet → SIMs → Add eSIM. The whole process takes under 60 seconds.
Can I keep my regular SIM while using this eSIM?
Yes. Most phones support dual SIM (physical + eSIM). Keep your home number for calls and SMS — use Flysimio for data abroad. You control which SIM handles what in your phone Settings.
Does the eSIM include a hotspot (tethering)?
Yes, all Flysimio plans include mobile hotspot at no extra charge. Share your data connection with laptops, tablets, or other devices freely.
What happens when my data runs out?
You can top up data from your account dashboard at any time. Top-ups are applied instantly — no need to buy a new eSIM or wait.
Can I get a refund?
Yes. We offer a full refund within 7 days of purchase. Contact contact@flysimio.com with your order number.
How long is the eSIM valid for?
You have 6 months from your purchase date to activate the eSIM. Once activated, the plan validity period (e.g., 7 days, 30 days) begins counting down.
Will the eSIM work at the airport when I land?
Yes — as long as you installed the eSIM before your flight, it activates automatically when your phone connects to a local network on landing. No Wi-Fi required for activation.
What if the QR code doesn't scan?
If the QR code won't scan, you can enter the activation code manually — we include both in the email. You can also contact our 24/7 support team and we'll resend or manually provision your eSIM.
eSIM in Croatia
The complete guide.
Best eSIM for travel to Croatia
The best Croatia eSIM combines strong coastal and island coverage, clear pricing, and instant setup. Flysimio runs on HT, A1 Croatia, and Telemach — networks that cover Dubrovnik, Split, and Zagreb, plus the Dalmatian islands and Plitvice Lakes — with 5G in the major cities. Plans are prepaid with no contract and no roaming bill surprises: choose your data, pay once, done. Your QR code arrives by email seconds after checkout and installs in under a minute, every plan includes free mobile hotspot, and a 7-day money-back guarantee has you covered. Land at Dubrovnik or Split already connected and skip the airport SIM counter entirely.
How to set up a Croatia eSIM (step by step)
Getting online in Croatia takes about two minutes. First, confirm your phone supports eSIM — iPhone XS (2018) and newer and most Android flagships from 2020 qualify. Choose your Croatia plan on Flysimio and pay with card, Apple Pay, or Google Pay; your QR code arrives by email within seconds. On Wi-Fi before you fly, open Settings → Cellular → Add eSIM (iPhone) or Network & Internet → SIMs → Add eSIM (Android) and scan it — a manual code is included too. Keep your home line as default until arrival. When you land at Dubrovnik, Split, or Zagreb, your Flysimio line connects automatically to a Croatian network — no kiosk, no physical SIM, no queue.
How much data do you need in Croatia?
Most travellers over-buy. For maps, messaging, and email, roughly 300 MB a day is plenty, so a 3–5 GB plan covers a week of island-hopping comfortably. Add social media, coastal photos, and music and you'll want about 700 MB a day — a 10 GB plan suits a two-week trip down the Dalmatian coast. Heavy streamers, video callers, and anyone tethering a laptop should plan for 1.5 GB or more per day or choose an unlimited daily plan. One note: island ferry crossings and remote beaches can weaken signal, so download maps first. Use the calculator above to size it, and top up mid-trip if you run low.
Using a Croatia eSIM on iPhone and Android
Flysimio runs as a second line beside your usual SIM, so you keep your home number for calls and texts while your Croatian data flows over the eSIM — standard dual-SIM behaviour on iPhone XS and later and most Android phones from 2018. After installing, set the Flysimio eSIM as your cellular-data line and turn on Data Roaming for that line only; it simply lets the eSIM connect to Croatian networks, with no roaming fees. Keep your home SIM on for messages and calls, or switch it off to avoid your own carrier's charges. If you're unsure about your model, the compatibility page confirms it before you buy.
Hotspot, calls, and texts on a Croatia data eSIM
Every Flysimio Croatia plan includes mobile hotspot at no extra cost and without throttling, so you can tether a laptop or tablet or share with a travel companion and use your full allowance freely. As a data-only eSIM it has no Croatian phone number, but that rarely matters: WhatsApp, FaceTime, Messenger, and Google Meet handle calls and messages over data, and your home number stays reachable on your primary SIM. You stay connected from Dubrovnik to the islands without the per-minute charges of traditional roaming.
Short Croatia trips vs. long stays
For a long weekend in Dubrovnik or Split, a small 1–5 GB plan on a 7-day validity is the most economical choice. For a two-week sail or coastal road trip down Dalmatia — or a longer stay — a 10–20 GB plan or an unlimited daily option lets you navigate, stream, and share without watching a meter. Because Flysimio gives you six months to activate, you can buy before you leave and the validity only starts when your eSIM first connects in Croatia. No contract, nothing to cancel — the plan stops when it's done, and you can top up or rebuy for your next trip.
