Airalo's Croatia page named **Telemach** as the primary network when we read it on 16 September 2026, with a **+1 other** button that resolves to A1. Hrvatski Telekom appears nowhere on the page, so roundups recommending that eSIM for Hrvatski Telekom coverage are describing a network it does not use.
On 16 September 2026 Airalo's Croatia eSIM page named Telemach as the primary network. The label sits directly under the Croatia heading, and the page's own accessibility text describes that field as the one that shows the primary network the eSIM uses. Beside it is a button reading +1 other, described in the same markup as the control that directs you to all networks the eSIM can use.
The product data behind that panel lists two Croatian networks, Telemach and A1, both flagged 5G. One of the product bullets spells it out, Operates on the Telemach and A1 networks in Croatia. Hrvatski Telekom is not in that list. It is not named anywhere on the page as a network the eSIM will attach to.
That matters, because the top results say something else. Four of the five we checked name Hrvatski Telekom or A1, and one builds a buying recommendation on the claim that Hrvatski Telekom has the widest reach along the Dalmatian coast and the islands. If the eSIM never touches Hrvatski Telekom, that argument is about the wrong carrier.
This is not a scoop. At least one page further down the same results already reports Telemach plus A1. It is just not what the top five say, and the top five are what people read. Network lists change when wholesale arrangements change, so the product page is the only place holding the current answer. See how a travel eSIM works for why the host network, rather than the brand on the checkout page, decides what your handset sees.
Three. HAKOM, the Croatian regulator, publishes quarterly coverage data for exactly three mobile operators. Its coverage maps page reads, This page provides information on the mobile network coverage of the operators A1 Hrvatska, Hrvatski Telekom, and Telemach Hrvatska. Telemach is one of the three, a network the regulator publishes radio coverage for in its own right rather than a brand reselling somebody else's signal.
So the Airalo page names a real Croatian network. Just not the one the roundups name. Here is what each source said on the day we read it.
| Source | Networks it names for Croatia | Hrvatski Telekom named |
|---|---|---|
| Airalo Croatia eSIM page | Telemach as primary, A1 behind the +1 other button | No |
| HAKOM coverage maps, the regulator | A1 Hrvatska, Hrvatski Telekom, Telemach Hrvatska | Yes, all three published |
| Top five search results for this question | Hrvatski Telekom or A1 in four of the five | Yes |
Three reasons, and not one of them is a look at the live product page. None of them is dishonest either, just stale. The problem is what gets stacked on top, because a coverage recommendation is a strong claim and here it is aimed at a carrier the product will not attach to.
We did not measure it, and neither did the pages that rank for the question. What does exist is an official answer you can read yourself, per operator, per technology, per location.
HAKOM publishes the coverage data quarterly and dates it on the map itself, Coverage data is published quarterly throughout the year, and the most recent quarter for which data has been published is indicated on the map. The coverage map application separates GSM, UMTS, LTE and 5G, and splits voice and SMS from data. You can select Telemach Hrvatska and look at Hvar, Vis, Korcula, Lastovo, or whichever stretch of coast you are going to.
The regulator attaches its own caveat, that the published data is informative and illustrative and that real user experience can differ with your circumstances and with network load. That is more useful than any roundup's ranking, because it says what the map cannot promise.
One practical note. On an island or a remote headland, what decides your signal is which cell sites are in range, not which brand is on your receipt. If coverage decides your trip, read the map for the network the eSIM actually uses, which today is Telemach, and read it for your specific islands rather than for Croatia as a whole.
Prices show in whatever currency the store is set to, and it was set to euros when we read it, so treat these as the euro figures rather than as a dollar or sterling price. Every Croatia local package on the default tab was unlimited data.
The same page offers broader products at lower entry prices, a European Union and United Kingdom eSIM from 4.00 EUR, a Europe eSIM from 4.50 EUR, and a global eSIM from 8.00 EUR. The page title read Croatia eSIM, from 4.00 EUR, which is that regional entry price and not the cheapest local Croatia plan.
Those regional eSIMs can sit on different Croatian networks than the local one, because the network panel is printed per product rather than per country. A regional plan is a separate check. If Croatia is one stop on a longer European run, read same price, three day eSIM, four countries before buying a stack of single country plans.
| Validity | Data | Price shown |
|---|---|---|
| 3 days | Unlimited | 8.50 EUR |
| 5 days | Unlimited | 16.50 EUR |
| 7 days | Unlimited | 22.00 EUR |
| 10 days | Unlimited | 25.50 EUR |
| 15 days | Unlimited | 34.50 EUR |
| 30 days | Unlimited | 52.00 EUR |
Check the Croatia network panelThe network names and the prices sit on the product page itself, and both change, so read them on the day you buy.Tracked on mobile web only, the page works on desktop too.
Any store worth buying from prints the host network on the product page. Reading it takes less time than reading a review of it.
If you were about to buy on the strength of a Hrvatski Telekom coverage argument, stop and re-read the panel. The eSIM on sale today rides Telemach first and A1 second, so the comparison that matters is Telemach against A1 on the regulator's map, for your islands, on the most recent published quarter.
If coverage on one specific island is make or break, a travel eSIM tied to one network is a weaker tool than a local prepaid SIM bought on arrival, where you pick the operator. For most coastal and city travel the difference will not show up.
And treat any figure on a page like this one as perishable. The same routine applies where the host network matters more than the headline price, Japan being the clearest example. Our methodology sets out what we read and what we refuse to estimate.
Telemach, as read on 16 September 2026. The Croatia product page names Telemach as the primary network and lists A1 behind a +1 other button, with one product bullet confirming it operates on the Telemach and A1 networks in Croatia. Check the panel again on the day you buy, because these lists change.
Not on the Croatia local eSIM we read on 16 September 2026. Hrvatski Telekom was not named anywhere on that page as a network the eSIM can use, even though several of the top search results say or imply that it is. That page named only Telemach and A1 for Croatia.
HAKOM, the Croatian regulator, publishes quarterly coverage maps for Telemach Hrvatska alongside A1 Hrvatska and Hrvatski Telekom, split by GSM, UMTS, LTE and 5G. Read the map for the places on your route. The regulator itself warns the data is illustrative and that real experience varies with network load.
Nobody can answer that for every island at once, and roundups that try are guessing. The regulator's coverage map lets you compare all three operators for a specific island and a specific technology on the latest published quarter, which is the only comparison that maps onto the trip you are actually taking.
Not directly. A travel eSIM carries whichever networks the provider has arranged, and the product page lists them. If you need one specific Croatian operator, a local prepaid SIM bought on arrival is the tool that gives you that choice, at the cost of arriving unconnected and queueing in a shop.
Open the country product page and look at the network panel under the country name. It shows the primary network plus a button such as +1 other that expands to the full list. The product bullets usually repeat the same information in words. Screenshot it with the date before you pay.
