# Croatia travel eSIM guide

> Croatia mobile data guide covering A1, Telemach and Hrvatski Telekom visitor offers, EU roaming, HAKOM coverage maps and ferry travel.

A Croatian trip can move quickly from Zagreb's airport to the Adriatic islands or across a land border. The choice of mobile data should follow that route: an EU or EEA home tariff may already roam in Croatia, while the published Croatian tourist packs differ sharply on cross-border use. Coverage on a particular island or sailing is another question, best checked before departure.

## A1's short-stay eSIM and shop-bought SIM

A1 Hrvatska sells tourist eSIMs online and sends the profile to the email address supplied at purchase. At the time of checking its page offered three days of unlimited 5G-labelled data for €10.90 and thirty days for €29, each with a combined allowance of 100 domestic minutes or text messages. A1 also advertised a ten-day two-SIM offer at €14.90 and a 120 GB, ninety-day option at €25. These are A1's current advertised prices and offers; confirm the selected product in checkout before paying.

The carrier says its ten-day physical tourist SIM is stocked at A1 shops, newsstands, petrol stations, supermarkets and Croatian post offices. That spread matters if you enter by road rather than through Zagreb airport: a small-town shop may be easier to reach than a mobile operator branch. A1 says the card starts when you first connect to the internet or make a call, so avoid inserting and using it earlier than necessary if the allowance must cover the end of the trip.

A1 describes the eSIM as rechargeable, with more days available after the starting period. Its instructions say to order and pay online, retrieve the profile from email and follow the activation steps. The page does not clearly set out any identity document condition for every sales route, so check the checkout or seller rather than assuming that online and counter purchases have the same requirements.

## Telemach and Hrvatski Telekom for different needs

Telemach's tourist page separates SIM2GO, with 10 GB and 200 minutes to Croatian numbers for thirty days, from NET2GO PLUS, with unlimited internet and 200 domestic minutes for ten days. It lists shops, post offices, grocery shops, petrol stations and newsstands as sales points. The card activates on the first call, text, data connection or voucher top-up. Telemach explicitly lists roaming among the services not included in these tourist packages, an important warning if the next stop is Slovenia, Bosnia and Herzegovina or Italy.

After expiry, Telemach's page lists a further 10 GB and 200-minute SIM2GO package for €9.16 and a further unlimited NET2GO PLUS period with 200 minutes for €7.96, both activated by text codes. Prices are those shown at the time of checking. Its account balance can be checked through the Telemach app, by text or by dialling the short code shown on its site. If you need to extend the stay, check that your line and the chosen renewal are still eligible before adding credit.

Hrvatski Telekom also has an online prepaid eSIM page for visitors. It says the activation QR code arrives by email and the eSIM can be ordered before the journey and used on arrival in Croatia. Its price fields did not render in the page we could check, so there is no defensible current price to quote here. It does provide phone-specific setup steps and explicitly asks customers to check eSIM compatibility before ordering.

## EU roaming on the Croatian side of a border

The European Commission includes Croatia in its roam-like-at-home area. For a traveller with an eligible EU or EEA home plan, ordinary calls, texts and data used during a periodic Croatian visit generally draw on the home tariff. The Commission says operators can apply a fair-use safeguard to unlimited or very cheap data, and they must tell customers about it. Check the home provider's allowance before paying for a separate tourist line.

A Croatian tourist SIM should not automatically be treated like an ordinary EU home plan. Telemach's visitor packages specifically exclude roaming, despite Croatia being in the EU. By contrast, the operator's separate SIM2GO S, M and L standard prepaid page describes EU or EEA data usage. Those are different products. If a trip heads from Dubrovnik towards a non-EU neighbour, or from Istria into Slovenia, ask what the exact product does at each border and switch data lines only after reading the operator's terms.

## Check HAKOM's maps for islands and routes

Croatia's telecom regulator HAKOM publishes operator coverage maps for A1 Hrvatska, Hrvatski Telekom and Telemach. They can be viewed by technology, including LTE and 5G, and HAKOM says operators submit new data quarterly. For a trip beyond major cities, check the particular island, port and accommodation rather than relying on a national marketing claim. The regulator warns that its maps are illustrative and that terrain, network load and different mapping methods can make real service diverge from the display.

HAKOM lists LTE availability across 700, 800, 900, 1800, 2100 and 2600 MHz bands and 5G availability across 700, 2100 and 3600 MHz bands. This is a list of bands that may provide the service, not a claim that every operator uses every band at every location. Phone compatibility and the chosen plan matter alongside the signal map. The regulator distinguishes its lower and higher signal classes, so read the map legend instead of treating any coloured area as a guarantee of fast downloads.

For domestic ferries, Jadrolinija allows passengers to search sailings and buy tickets online, and says a ticket saved on a phone is enough for boarding without printing. Save that ticket locally before going to the port, especially for an island crossing where mobile signal may be uncertain. The ferry company's service notices can also be checked online before travel; keeping a data connection helps if a sailing changes.

## A workable setup at Zagreb airport

Franjo Tuđman Airport says free Wi-Fi is available throughout its passenger terminal. Its named network is Zagreb_Airport_Free, and connecting requires acceptance of the terms and privacy notice. That is useful for retrieving an emailed A1 or Hrvatski Telekom QR code after landing, although installing a profile before departure avoids depending on an airport login at the moment you need directions.

Before flying, make sure the phone supports eSIM and is unlocked if you intend to keep a home line from another operator. Apple says its supported Dual SIM phones can assign one line to data and another to voice or messages, but use one mobile data network at a time. On arrival, select the Croatian or roaming line deliberately for data and check the home line's roaming settings. If the new profile fails, A1's guide and Hrvatski Telekom's setup page both describe the QR-based installation path.

Keep a separate way to make an ordinary call if your selected travel profile supplies only data. A1's cited tourist eSIMs list a small domestic minutes or texts allowance, while a data-only product may differ. Check the product actually purchased rather than assuming all eSIMs have a Croatian number or voice service.

## Emergency calls and the final plan check

The European Commission says 112 is the free emergency number across the EU, including Croatia, and that a roaming provider should send visitors information about it on arrival. A data-only eSIM should not be assumed to make a normal voice call to 112; keep a voice-capable line or another reliable means of calling available. This is particularly relevant on an island or a remote coastal road, where a messaging app cannot replace a direct emergency call.

For a week centred on Split or the Dalmatian islands, A1's ten-day option and Telemach's ten-day NET2GO PLUS should be compared on voice needs, renewal and actual mapped coverage. For a longer road trip, A1's thirty-day eSIM or a conventional prepaid line may align better with the calendar. If the stay is mostly within EU countries and you already have an eligible home tariff, first check its Croatian fair-use allowance; buying a new line may offer little benefit.

Record the plan expiry date when it starts. Download ferry tickets, accommodation details and offline route information while connected. Where you intend to use a Croatian line over a border, verify the selected product's roaming terms specifically: the word tourist on a pack does not establish what will work after leaving Croatia.

Emergency calls: Many travel eSIMs carry data only, and a data-only profile may not place a normal phone call. Keep a voice-capable SIM for emergencies, such as your home SIM or a local plan, and save the local emergency number from this guide.

## Questions

### Will my EU mobile plan roam in Croatia?

Croatia is within the EU roam-like-at-home area. An eligible home plan normally applies its domestic terms during a periodic visit, but unlimited or cheap data can have a fair-use limit; check your provider's message and allowance.

### Can I order a Croatian eSIM before arriving?

A1 sells tourist eSIMs online and emails the profile. Hrvatski Telekom also says visitors can order its prepaid eSIM anywhere and use it on arrival; check compatibility before purchase.

### Does a Telemach tourist SIM work across the border?

Telemach lists roaming among the exclusions for its SIM2GO and NET2GO PLUS tourist packages. Its ordinary prepaid products have separate terms, so check the exact pack rather than assuming EU roaming applies.

### Which regulator map should I check for a Croatian island?

Use HAKOM's operator coverage maps to compare the intended island or port for A1, Hrvatski Telekom and Telemach. They are based on operator submissions and are indicative rather than a signal guarantee.

### Is there free Wi-Fi at Zagreb airport?

The airport says its Zagreb_Airport_Free network covers the passenger terminal. It asks users to accept its terms and privacy notice before connecting.

### Can I board a domestic Jadrolinija ferry with a phone ticket?

Jadrolinija says a ticket stored on a mobile device can be shown for boarding without printing. Save it on the device before heading to the port.

### What emergency number works in Croatia?

The EU emergency number is 112. Keep a voice-capable way to call; do not assume that a data-only travel eSIM itself can place a normal emergency voice call.
