Prices read on 28 September 2026. Six travel eSIMs sell a Slovenia plan and get most of the traffic for this search.

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 has no speed cap: the 2 weeks starts with 10 GB and the 30 days with 20 GB, and when you have used 80% we add 10 GB once and charge the $12.99 top-up. A heavy two weeks with us costs $25.98 and a heavy month $34.98, both still under every rival for the same length.
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.
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.
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 starts with 10 GB for $12.99 and our 30 days with 20 GB 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.
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, starting with 10 GB, and 30 days at $21.99, starting with 20 GB. Each adds 10 GB once at 80%, charged at $12.99. One payment, nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app.
The card to buy it is just below this article.
A long weekend in Ljubljana. Nomad unlimited, 3 days, $11. Ringo Light sells no 3 days; its 2 weeks is $12.99 if the trip might run longer.
A week or two from Ljubljana to Bled, the Soča and Piran. Ringo Light unlimited, 2 weeks, $12.99, less than any rival charges for one week.
Two weeks, light use, budget first. Ubigi 10 GB for 30 days at $13, or its 10 GB for 7 days at $10.

You need your own number to keep ringing. None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.
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.
The Triple Bridge and Prešeren Square, Ljubljana. Three bridges side by side over the Ljubljanica river, two of them added by the architect Jože Plečnik in the 1930s, lead into the main square under the pink Franciscan church. The old town around it is car free and made for walking. City buses take no cash on board: buy an Urbana card at a kiosk or the tourist office before your first ride.
Lake Bled and its island church, Bled. A church on the only natural island in Slovenia, reached by a traditional pletna rowing boat, with the castle on its cliff above the shore. The walk around the lake is about six kilometres. The car parks by the lake fill up by mid-morning in summer. Check a map for the lots on the edge of town, or take the bus from Ljubljana.
Vintgar Gorge, Near Bled. A wooden boardwalk of about 1.6 kilometres above the clear green Radovna river, between walls of rock. It is a short drive or bus ride from Bled, and closes over the winter. Buy the ticket online before you go: in summer the entry times sell out.
Lake Bohinj, Triglav National Park. The largest permanent lake in Slovenia, quieter than Bled, ringed by mountains, with the Savica waterfall and the Vogel cable car at its western end. Swim, paddle or walk the shore. Signal fades on the trails above the lake. Save an offline map before you set off.
The Vršič Pass, Between Kranjska Gora and the Soča Valley. The highest road pass in Slovenia, 1,611 metres, climbing through fifty numbered hairpins past the wooden Russian Chapel. Open in the warmer months; it closes when the snow comes. Check promet.si, the national traffic site, for closures before you drive up.
The Soča Valley, Bovec and Kobarid. An emerald river running from the Alps towards Italy, known for rafting, kayaking and the Great Soča Gorge. Bovec is the base for most trips on the water. Holafly itself warns that signal is weaker here. Download the day's map and trail before you leave the village.
Predjama Castle, Near Postojna. A castle built into the mouth of a cave halfway up a cliff, about ten kilometres from Postojna Cave, whose tunnels you ride into on a small train. Most people see both in one day. Postojna Cave tours run at set times; book the combined ticket with the castle online.
Piran old town, The Slovenian coast. A Venetian town of red roofs on a narrow peninsula, around Tartini Square and under the bell tower of St. George's Church. Climb the town walls for the view over the Adriatic. Cars stay out of the old town: park in the Fornače garage at the edge and ride the shuttle bus in.
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.

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.
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.
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 has no speed cap: it starts with 10 or 20 GB and adds 10 GB once at 80%, charged.
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.
