1 · The short answer

Six travel eSIMs sell a Slovenia plan and get most of the traffic for this search. We priced all six on the same day, for a long weekend in Ljubljana, two weeks between the Julian Alps, the caves and the coast, and a month, and read the fine print on unlimited. Here is where each one wins.

4 · What to do in Slovenia, and what your phone needs for it

Eight places most first trips include, from Ljubljana up into the Julian Alps, down to the caves of the Karst and out to the coast at Piran, with the one thing your data does for you at each. The towns and the motorways have good 4G and 5G; the high passes and the deep valleys are where signal thins.

5 · If you want unlimited for two weeks or a month: Ringo Light

Slovenia is small, and most people see it in one or two weeks: Ljubljana, Lake Bled, the Soča Valley, the caves at Postojna and a night on the coast at Piran. For 15 days of unlimited, Airalo asks $45, Saily $48.99 and Holafly $50.50. Ubigi sells no unlimited Slovenia plan; its Europe plan gives 30 GB at full speed for $35. Nomad stops at 10 days, for $33. For a month, $62 to $73.90 on one payment. Ringo Light charges $12.99 for 2 weeks and $21.99 for 30 days, one payment each, nothing renews.

Read what unlimited means before you pick. Airalo gives 3 GB a day at full speed, then 1 Mbps. Saily gives 5 GB a day, Nomad 2 GB. Ubigi gives a fixed amount, 60 GB for the month, then 2 Mbps. Holafly states no daily cap for your own phone and limits sharing to 1 GB a day. Ringo Light is unlimited data at full speed for the whole 2 weeks or 30 days, one payment.

For a short trip, Ringo Light sells no 3-day or 7-day plan. Nomad sells 3 days of unlimited at $11 and a week at $25. Our 2 weeks at $12.99 still costs less than any rival's unlimited week.

6 · Which network works best in Slovenia, and the mountains

Slovenia has three big networks: Telekom Slovenije, A1 and Telemach, plus the smaller T-2. All of them cover Ljubljana, the motorways, Bled and the coast well. Signal gets patchy in the Julian Alps, deep in Triglav National Park, in parts of the Soča Valley and in the Kočevje forests; Holafly says as much on its own page. Holafly is the one brand of the six that names all three big networks. Nomad rides Telemach and Telekom Slovenije, Ubigi A1, and Airalo T-2.

Slovenia is in the EU and uses the euro. Cards and phone wallets work almost everywhere in the towns; carry a little cash for mountain huts and farm stalls. The motorways need a vignette, and since 2022 it is only sold as an e-vignette, bought online against your number plate.

7 · If you want a data bucket: Ubigi or Nomad

  • Ubigi, $13 for 10 GB. The cheapest 10 GB that lasts 30 days, on A1 with 5G, installed by QR code, no app needed. 10 GB for 7 days is $10.
  • Nomad, $16 for 10 GB. And the cheapest 20 GB at $20, on Telemach and Telekom Slovenije.
  • Airalo, $19 for 10 GB. Its Živjo plan, 20 GB for $34, buckets from $4 for 1 GB. The app is needed.
  • Saily, $19.99 for 10 GB. 20 GB at $33.99. Its listing is from June; we could not read saily.com on the day.
  • ✓Ringo Light, no buckets. Our 2 weeks is unlimited for $12.99 and our 30 days unlimited for $21.99. For 10 GB that lasts a month, Ubigi at $13 is the better buy, and Nomad sells 20 GB for $20, a little under our 30 days. We would rather you read that here than at checkout.

8 · What Ringo Light is

Ringo Light is our own data eSIM, sold to fund the full Ringo, one plan that works everywhere with your own number ported onto it. For Slovenia it sells two trips, both unlimited data at full speed with no speed cap: 2 weeks at $12.99 and 30 days at $21.99. One payment, nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app.

The card to buy it is further up this page, just after the side-by-side table.

Two weeks, light use, budget first

Ubigi 10 GB for 30 days at $13, or its 10 GB for 7 days at $10.

10 · Frequently asked questions

Which eSIM is cheapest for Slovenia?+
For two weeks or a month of unlimited data, Ringo Light: $12.99 for 2 weeks and $21.99 for 30 days on 28 September 2026, against $45 for 15 days and $69 for 30 days at Airalo. For 3 days, Nomad at $11. For 10 GB over 30 days, Ubigi at $13; for 20 GB, Nomad at $20.
Which Slovenian network will my travel eSIM use?+
Airalo rides T-2, Holafly A1, Telekom Slovenije and Telemach, Nomad Telemach and Telekom Slovenije, and Ubigi A1. Saily does not name its network on its listing. All cover the towns, the motorways and the coast; signal thins in the Julian Alps and the deep valleys.
Is an unlimited eSIM really unlimited in Slovenia?+
Every brand has a limit somewhere. Airalo slows you after 3 GB a day, Saily after 5 GB, Nomad after 2 GB, Ubigi after its fixed full-speed amount. Holafly states no daily cap for your own phone. Ringo Light is unlimited data at full speed.
Do I need an eSIM if my phone plan covers the EU?+
Slovenia has been in the EU since 2004, so a home plan from an EU country usually roams there at home prices, within a fair use limit. Travellers from the US, the UK, Canada or Australia usually pay a daily roaming fee, and that is where a travel eSIM saves money. A Slovenia plan stops at the border, so a day trip to Trieste or Croatia needs a Europe plan.

11 · How we compared, and our sources

We priced Airalo, Holafly, Saily, Nomad, Ubigi and Ringo Light for Slovenia on 28 September 2026, all on the same day, in US dollars. Each rival's price comes from its own website where it showed dollars, otherwise from an esimdb.com listing, and every source and its date is listed below. Ringo Light's prices come from the catalogue our checkout charges.

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.

Written and priced by the Ringo team. Prices change often; if you spot one that has moved, tell us through the contact page and we will update the table.
