For a typical Croatia trip, I would start with Nomad’s 20GB plan at €18.68 for 30 days. It gives you one allowance to use across the trip, supports hotspot and lists Telemach and A1. If you would rather buy unlimited data, compare the daily speed allowance first: Airalo, Nomad and Saily slow down after different amounts of high-speed use, while Holafly applies fair-use conditions and a separate hotspot allowance.
Island plans need a little more care than a price table can provide. The signal at your apartment, a sheltered beach and a ferry terminal can be very different, even on the same island. Check your actual stops, save your tickets offline and avoid choosing a plan on the promise of perfect island coverage. Hrvatski Telekom also sells tourist eSIMs online, so it is worth checking alongside the four travel providers below.

Quick answer: which Croatia eSIM would I choose?
Fixed data: Nomad 20GB/30 days, €18.68, with Telemach + A1 and hotspot.
A short unlimited break: Airalo 3 days, €9; 7 days, €23. Both include a daily speed limit.
Unlimited data on your phone: Holafly 7 days, €25.50, with 1GB/day of hotspot and fair-use conditions.
A longer unlimited stay: Saily 30 days, €52.49, with 5GB/day at high speed, then up to 1Mbps.

Croatia eSIM prices: fixed data and unlimited plans
Compare the same amount of data and the same validity before judging the price. A 5GB package valid for seven days is not interchangeable with a 30-day package. These are the public EUR totals I saw on 24 October 2026, before any eligible reader discount.
For a week in Split with day trips, 10GB is a sensible starting point if you use accommodation Wi-Fi for large downloads. For an island circuit, I would consider 20GB if you expect frequent uploads or hotspot use. These are planning estimates, not measured consumption. Video calls, cloud backups and streaming can change the calculation quickly.
Fixed Data Plans
| Package | Nomad eSIM | Airalo | Saily |
|---|---|---|---|
| 1GB | €3.56 / 7 days | €4 / 3 days | €3.49 / 7 days |
| 3GB | €6.23 / 30 days | €7 / 7 days | €6.99 / 30 days |
| 5GB / 30 days | €8.01 | €10 | €9.99 |
| 10GB / 30 days | €13.34 | €16 | €15.99 |
| 20GB / 30 days | €18.68 | €23.50 | €24.99 |
| 50GB / 30 days | €27.57 | €32.50 | Not listed |
Unlimited Plans
| Duration | Nomad eSIM | Holafly | Airalo | Saily |
|---|---|---|---|---|
| 3 days | €9.78 | €11.42 | €9 | Not listed |
| 5 days | €16.01 | €18.50 | €17 | €16.99 |
| 7 days | €22.24 | €25.50 | €23 | €22.25 |
| 10 days | €29.35 | €34.90 | €26.50 | €25.99 |
| 15 days | Not listed | €47.90 | €35.50 | €34.49 |
| 30 days | Not listed | €70.90 | €54 | €52.49 |
What “unlimited” means here: Nomad gives 2GB/day at high speed, then 1Mbps. Airalo gives 3GB/day, then 1Mbps. Saily gives 5GB/day, then up to 1Mbps. Holafly has no fixed total data allowance, but local fair-use management can reduce speeds and hotspot is limited to 1GB/day. The Croatia page does not publish one universal numeric high-speed threshold for Holafly. For laptop work, read these conditions as carefully as the price.
Nomad is the lowest-priced 10GB and 20GB option among the four travel providers reviewed here. For seven days of unlimited data, its €22.24 price is only one cent below Saily’s €22.25, while Saily includes a larger daily high-speed allowance. Airalo’s three-day unlimited plan is €9. For 30 days, Saily is €1.51 below Airalo and €18.41 below Holafly. The network disclosure and hotspot rules still deserve a place in the decision.
Four travel eSIM providers worth comparing for Croatia
Nomad eSIM
Telemach + A1 · 20GB/30 days €18.68 · Hotspot supported
Nomad is my starting point when I want a simple allowance I can spread over the whole holiday. The 20GB/30-day package costs €18.68, or about €0.93 per GB, and the 50GB option is €27.57. A busy upload day does not use up a separate daily allowance on these fixed-data plans.
The official 20GB and seven-day unlimited package details both list Telemach / A1, hotspot support and data-only service. Two listed networks give you another connection option where both are available. They do not guarantee that the phone always selects the fastest signal, or that every beach has coverage.
| Plan | Price | Useful distinction |
|---|---|---|
| 1GB / 7 days | €3.56 | Light use over a short trip |
| 5GB / 30 days | €8.01 | Maps and messages with Wi-Fi backup |
| 10GB / 30 days | €13.34 | A practical starting allowance |
| 20GB / 30 days | €18.68 | More room for uploads and hotspot |
| 50GB / 30 days | €27.57 | A larger total allowance |
| Unlimited / 7 days | €22.24 | 2GB/day at high speed, then 1Mbps |
The plan starts when it connects to a supported destination network, or automatically after 60 days if unused. Some installation instructions can differ by package, so keep the confirmation email. Fixed-data add-ons are listed; the unlimited package checked does not offer an add-on. For a Croatia-only trip, I would normally choose the fixed 20GB option before paying for a daily unlimited allowance I may not need.

Holafly
Telemach + A1 · 7 days €25.50 · 1GB/day hotspot
Holafly makes sense when you want unlimited data on your phone and do not want to manage a total allowance throughout the trip. The seven-day Croatia plan is €25.50. The current network list is Telemach Croatia / A1 Hrvatska, so I would not pay more expecting an additional Croatian carrier.
I have used Holafly in Portugal, Turkey and Thailand. That experience helps with setup expectations, but it does not establish the signal in a particular Croatian bay. The current Croatia page itself cautions about mountainous areas, sparsely populated islands and sea journeys.
| Duration | EUR price |
|---|---|
| 3 days | €11.42 |
| 5 days | €18.50 |
| 7 days | €25.50 |
| 10 days | €34.90 |
| 15 days | €47.90 |
| 30 days | €70.90 |
Before buying, check Holafly’s eligibility terms. The service is intended for international travel; its domestic-use restriction treats the EU as a single domestic region for EU-based customers. If you live in the EU and are visiting Croatia, confirm eligibility with Holafly before purchase.

Use this installation video alongside the instructions in your purchase email. The Croatia plan terms above are the current reference for hotspot, price and activation.
Airalo
Telemach + A1 · 7 days unlimited €23 · 3GB/day at high speed
Airalo is worth considering for a short break or when you like managing top-ups in one app. Its three-day unlimited plan costs €9, while seven days costs €23. The selected unlimited package gives 3GB/day at high speed before reducing the connection to 1Mbps.
The Croatia network panel lists Telemach as primary, plus A1. Its package notes explicitly mention the mainland, Hvar, Brač, Korčula and the Dubrovnik area. That is a useful disclosure, but it is not a guarantee for every building or cove, and it does not establish a coverage advantage over another plan using the same networks.
| Fixed-data example | Price | Unlimited example | Price |
|---|---|---|---|
| 1GB / 3 days | €4 | 3 days | €9 |
| 5GB / 7 days | €9 | 5 days | €17 |
| 10GB / 30 days | €16 | 7 days | €23 |
| 20GB / 30 days | €23.50 | 15 days | €35.50 |
| 50GB / 30 days | €32.50 | 30 days | €54 |
The package checked allows 365 days from purchase to begin using the eSIM. Validity starts with connection to a supported network in the coverage area, and top-ups become available after installation. Hotspot uses the same allowance and speed conditions as phone data. For a multi-country trip, compare the exact country lists of Airalo’s Europe and EU+UK packages: the names are different for a reason.

Airalo eSIM setup video
This video explains the setup approach. Compare the Croatia-only plan with a regional package if your route crosses a border; do not assume that every plan labelled Europe includes the Western Balkans.
Saily
Carrier not disclosed · 30 days unlimited €52.49 · 5GB/day at high speed
Saily’s €52.49 for 30 days of unlimited data is the lowest 30-day unlimited total among these four travel providers. The selected offer provides 5GB/day without a speed limit, then unlimited data at up to 1Mbps. That extra daily allowance can matter more than a small price difference if you regularly upload photos or tether a laptop.
I have not personally tested Saily. Its Croatia page does not name the local operators, so I cannot claim that it has the same coverage as Nomad, Holafly or Airalo. If access to a particular network is essential, settle that question with Saily before purchase.
| Fixed data | Price | Unlimited | Price |
|---|---|---|---|
| 1GB / 7 days | €3.49 | 5 days | €16.99 |
| 3GB / 30 days | €6.99 | 7 days | €22.25 |
| 5GB / 30 days | €9.99 | 10 days | €25.99 |
| 10GB / 30 days | €15.99 | 15 days | €34.49 |
| 20GB / 30 days | €24.99 | 30 days | €52.49 |
Saily allows 180 days to activate a plan and then activates it automatically if it remains unused. Arrival activation requires the eSIM to be enabled with roaming on. The page lists no separate hotspot restriction, but unlimited speed limits still apply to shared data.
Saily’s security tools include virtual location, ad blocking and web protection. That is not the same as automatically receiving a full NordVPN subscription. The service also offers a separate US phone number and calling/text plans; those are not a Croatian number included in the data prices here. I have left conditional travel perks out of the price comparison so the data plan stands on its own.

Croatian island coverage: check the stop, not just the island name
A network label tells you which operator a package can use. It cannot tell you whether your room faces a hillside, whether the ferry is within reach of a coastal tower or how busy that tower will be. HAKOM’s map service separates indoor and outdoor coverage and 4G/5G layers. The regulator also explains that maps are indicative and actual experience can differ. Search the accommodation address and a few important stops rather than treating an entire island as one result.
| Where you are going | What I would check | What to save offline |
|---|---|---|
| Dubrovnik, Split, Zagreb or Zadar | Your accommodation, especially indoor reception | Arrival directions and booking details |
| Hvar and Brač | The town, beach and road segments separately | Ferry ticket and the drive to your stay |
| Korčula and Vis | Both ends of the island and any secluded bay | Route and accommodation contact |
| Mljet, Lastovo or Susak | Specific accommodation and excursion stops | Maps, tickets and the last return departure |
| Ferry crossings or sailing | Whether the connection is terrestrial or an onboard network | Everything needed until the next port |
| Plitvice and mountain routes | The operator map for the route, not only the nearest town | Trail information and transport details |
I would not describe Mljet or Lastovo as generally offline, or declare one operator the winner on every outer island without route-level evidence. If your host recommends a particular local network, check whether your chosen package lists it. HT’s direct eSIM is an option when you specifically want its network. For destination planning, keep the official Croatian tourism information close to hand. Related reading: Croatia Tourism official site

EU roaming, nearby borders and the local eSIM alternative
Croatia is in the EU roaming area. If you already have an eligible home plan from that area, check its Croatia allowance before buying another eSIM. It may cover your needs. Fair-use limits can still apply, especially on unlimited home plans. Schengen membership and the euro are useful travel facts, but neither proves that a particular travel eSIM includes Croatia.
A Croatia-only eSIM is not automatically a regional plan. For Slovenia or Italy, look at the country list on the exact Europe package. For Mostar in Bosnia and Herzegovina or Kotor in Montenegro, check separately: those countries are not currently included in the EU’s Roam Like at Home area. A provider may include them in a regional offer, but that is a commercial inclusion rather than an EU roaming entitlement. The European Commission explains the current roaming rules.
At sea, an ordinary Croatia data plan should be treated as a land-network product. EU roaming price protections do not cover satellite-based onboard networks. Disable your home SIM’s data roaming, avoid automatic data switching and use airplane mode when you want to rule out an unexpected maritime connection. Turn Wi-Fi back on separately if you use a ship’s Wi-Fi service.
If your itinerary combines Croatia with Slovenia, Italy or Greece, work out the total cost and country list for the whole trip before buying individual country packages. Related reading: Best eSIM for 30 Days in Europe
Before you leave: setup and ferry planning
A few minutes of preparation helps more than buying an oversized data package. I would deal with installation, offline directions and the next ferry ticket before travelling, while I still have reliable Wi-Fi.
- Check the ferry’s booking rule. Jadrolinija offers reserved vehicle departures on designated routes, including Split-Vis and Split-Stari Grad. Other vehicle services depend on the queue. Read the rule for your exact route and ticket type, and meet the operator’s arrival deadline. Jadrolinija’s reservation guidance is the reference.
- Install on Wi-Fi before departure. Confirm your phone supports eSIM and is network-unlocked. Label the travel line clearly, select it for mobile data and follow its roaming instructions.
- Keep tickets offline. Save the ferry ticket, accommodation address and onward route on the phone. A screenshot or downloaded file is more useful than a booking page that needs to reload at the port.
- Ask your host about the location. If reliable data is essential for work, ask about reception in the actual apartment and whether there is usable Wi-Fi. A national network award does not answer that question.
- Keep your home number without accidental data roaming. Leave your home SIM available for verification messages if needed, but check its calls and roaming charges. Turn automatic mobile-data switching off.
- Check each border on the route. A day trip to Montenegro or Bosnia may need an additional package or a different regional plan. Check validity and data before setting off.

Final Verdict: the Croatia eSIM I would actually buy
If I were planning a week or two split between a city and the islands, Nomad’s 20GB/30-day plan at €18.68 would be my first comparison. It is a useful amount of data at a competitive price, with hotspot and a published Telemach + A1 network list. I would choose it because the allowance fits the trip, not because it can promise a signal in every cove.
For a short, data-heavy break, Airalo’s €9 three-day unlimited plan is worth a look. For a longer stay, Saily’s €52.49 month offers 5GB/day at high speed, but I would settle any carrier question with support before buying. Holafly remains an option for someone who prefers unlimited phone data and is comfortable with its price, eligibility terms and 1GB/day hotspot limit. If a laptop will be online for hours, that hotspot allowance is a deciding detail.
I would also compare HT’s direct tourist eSIM. Its online purchase option corrects the idea that a local plan means landing disconnected and finding a shop. For a Croatia-only holiday, its price and local minutes may be useful; for a wider Balkans route, its lack of roaming allowances may rule it out.
My final check would be the same whichever brand I chose: look up the accommodation and important island stops, download the next ferry ticket and keep a map offline. Spend enough for the data you will use, and let the itinerary decide the rest.
