The short answer
The trip is two small countries and one short border, Ljubljana to Zagreb or Piran to Istria, and I priced the Europe plans that cover both on 25 October 2026. The one I would buy is Ringo Light: $22.99 for 2 weeks or $35.99 for 30 days of unlimited data at full speed, one install for both. For 3 days Airalo is cheapest at $11.50, and for a 10 GB bucket Ubigi at $15.
One eSIM on both sides of the border: unlimited data at full speed for 2 weeks at $22.99 or 30 days at $35.99, nothing renews. Airalo Eurolink asks $49 for 15 days and $71 for the month.
10 GB for 30 days at $15, plenty for ferry times, maps and the odd upload. Its 15 days is 30 GB at full speed, then 2 Mbps, for $35.
Eurolink covers 41 countries, so Croatia and Slovenia are two of many. 3 days of unlimited at $11.50, 5 GB a day at full speed.
Days, not gigabytes, in 33 countries. No daily cap stated for your own phone; sharing limited to 1 GB a day. $27.50 for a week.
Prices read on 25 October 2026: Airalo, Holafly, Saily, Nomad, Ubigi on their own sites or listings, Ringo Light from its catalogue. All in US dollars unless stated. Treat every number as a snapshot.

It is a separate product from Ringo Light and it is still being built, so it is not on sale yet. Join the waitlist to hear when it opens.
What to do in Croatia and Slovenia, and what your phone needs for it
Seven places that fill a trip between the Adriatic and the Julian Alps, with the one thing your data does for you at each. Both countries sit inside the Europe plan, so one eSIM follows you from the first to the last.
One plan for both countries: Ringo Light
Croatia and Slovenia are neighbours that people visit in one go, so a single regional plan fits the way the trip is built. You install the Europe eSIM before you leave, and when the road from Piran or Ljubljana crosses into Croatia it picks up a Croatian network on its own. Two country eSIMs ask you to buy twice and to switch the data line on the day you cross.
The regional plan wins on price as well. Ringo Light's Europe trips are $22.99 for 2 weeks and $35.99 for 30 days, unlimited data at full speed. Airalo Eurolink asks $49 for 15 days, Saily $49.99 and Holafly $51.50, and $71 to $76.50 for a month. Ubigi asks $35 for 15 days, then 2 Mbps after 30 GB.
I added the country pages together to be sure. Croatia's 2 weeks is $16.99 and Slovenia's $12.99 on their own pages, $29.98 together, against $22.99 for the Europe trip that covers both. For a month it is $26.99 and $26.99, $53.98 together, against $35.99. Country plans are for people who will stay on one side of the line.
Which plans cover both countries
Croatia and Slovenia are both EU countries, so both sit in the core of every Europe plan in the table. I could only confirm full lists from the Europe page I priced. Ringo Light covers 33 countries, the EU countries plus the UK, Switzerland, Norway, Iceland, Liechtenstein and Gibraltar, so both are in. Airalo Eurolink covers 41, both in.
Holafly lists 33 countries, Saily 35, Nomad 35 on its unlimited plans and Ubigi 38. For those four I could not confirm a country by country list on the day, so look for Croatia and Slovenia on the checkout page. If your route drifts on to Bosnia or Montenegro, those are outside what I confirmed, and Airalo Eurolink is the one the parent page lists for Bosnia.
If you want a data bucket: Ubigi or Nomad
- Ubigi, $15 for 10 GB. The cheapest 10 GB for 30 days across 38 countries. 25 GB is $29, and a 20 GB monthly plan at $19 renews until you cancel it.
- Nomad, $23 for 10 GB. And 20 GB for 30 days at $27, the cheapest one-off 20 GB in the table.
- Airalo, $31 for 10 GB. Eurolink 20 GB for 30 days is $48, and it has the longest country list.
- Saily, $35.99 for 10 GB. Read on saily.com, 25 October 2026.
- ✓Ringo Light, no buckets. On a light-use trip through Croatia and Slovenia, Ubigi's 10 GB at $15 is $7.99 under Ringo Light's 2 weeks, and Nomad's 20 GB at $27 is $8.99 under its 30 days. I would still buy Ringo Light for unlimited. I put the rival figures here so you hear them from me first.
What Ringo Light is
Ringo Light is the data eSIM Ringo sells to fund the full Ringo, one plan that works everywhere with your own number ported onto it. I write for Ringo, so weigh that. For Croatia and Slovenia it sells the Europe trip across 33 countries, unlimited data at full speed: 2 weeks at $22.99 and 30 days at $35.99. Nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app. At the border it moves to a local network on its own.
The card to buy it is further up this page, just after the side-by-side table.
Pick by trip
Airalo Eurolink 3 days at $11.50. Ringo Light sells no 3-day Europe plan, so for a short stay the rival wins.
Ringo Light unlimited, 2 weeks, $22.99: the whole trip on one eSIM, and $6.99 less than the two country plans at $29.98.
Ringo Light unlimited, 30 days, $35.99. Ubigi at $62 if you want a fixed 60 GB.
Ubigi 10 GB for 30 days at $15, valid in both countries.
Airalo Eurolink is the one the parent page lists for Bosnia. Ringo Light does not cover it, and I did not confirm Montenegro anywhere.
None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.
Frequently asked questions
How we compared, and our sources

We compare the trips people actually book: a week, two weeks and a month of unlimited data, and a 10 GB bucket. We read each brand's fair use and speed rules and quote them as the brands state them. We did not run speed tests, so this page makes no speed claims for any brand.
Ringo Light is our own product. We put it in the table on the same terms as everyone else, and where a rival is the better buy the page says so.
Left out: Maya Mobile. We could not read its own prices for this country on the day, so it stays out rather than being guessed.
