eSIM for Slovenia

Data for Ljubljana, Bled and the drive south, installed before you leave. Slovenia is on the Europe plan, not the Balkans plan, so the same eSIM carries on into Croatia, Serbia, North Macedonia and Albania. And yes, it is the one with the sea.

Good to know

What's included, when it starts, and how to get connected.

Included countries
The Slovenia plan covers Slovenia only.
Local networks
In Slovenia your eSIM connects to Telekom Slovenije and Telemach — 4G/5G where the network offers it.
When validity starts
Your package starts when your phone first connects to a network at the destination — not when you install it. Crossing a border does not restart it.
Installation and activation
Install the eSIM while you still have internet — at home or on Wi-Fi. Installation does not start validity. If you already have a onesim eSIM installed, a new package is added to it — no second installation. Setup guide
Calls and texts
onesim is data-only. Calls and messages work over data in apps like WhatsApp or FaceTime; your usual SIM keeps your number.
Support and refunds
Message the onesim support team from the app or the website. If a package cannot be installed or used, the refund policy explains what applies. Refund policy
Travel notes

What the A2 does not tell you.

Kayaks and swimmers on Lake Bohinj below the mountains
Driving

The vignette is a number plate now, not a sticker.

Slovenia’s motorway vignette has been electronic since February 2022: you buy it on evinjeta.dars.si or at a petrol station against your registration, and cameras check it. The 7-day one costs €16 in 2026 and covers a transit drive. Type the plate carefully, because a typo counts as not paying — and driving the motorway without a valid one is a €300 fine.

Driving

The Karawanken tunnel has its own toll, and in August its own queue.

No vignette covers it: the tunnel costs €9 per car each way in 2026, paid at the toll station, and that ticket takes you to the first exit on the other side. A second tube opened in March 2026, but the old one then closed for renovation until the end of 2028, so it is still one tube, both directions. On 15 August 2026 the southbound wait reached 90 minutes.

Hot take

Bled is the poster. Bohinj is the holiday.

Bled is 10 minutes off the motorway and on every Slovenia poster, and by late morning everyone who saw those posters is standing on its shore. Have the cream cake — Hotel Park has made more than 16 million since 1953 — then keep driving: Lake Bohinj, half an hour on, is more than twice the size, wilder and much quieter.

The meme

Slovenia has the sea. Slovakia is the other one.

Two Slavic names, two white, blue and red flags with a mountain in the coat of arms, and years of each other’s post. The monthly embassy meet-up in Washington to swap misaddressed mail is a legend both embassies deny — but a Slovenian diplomat in 1990s London said they did bundle up each other’s letters and send them across. The quick test: Slovenia has 47 kilometres of coast. Slovakia has none.

Only here

2.1 million people, five Tours de France and Luka Dončić.

Tadej Pogačar won his fifth Tour de France in July 2026, joining Anquetil, Merckx, Hinault and Induráin on the record — at 27, the youngest of them to get there. Luka Dončić is the Lakers’ star, and Janja Garnbret has two Olympic climbing golds. Slovenians will tell you this is normal for a country of 2.1 million. It is not.

Worth the stop

Slovenia deserves more than the A2 at 3 a.m.

From the Karawanken to the Croatian border the A2 is 175 kilometres, and in July it fills with German and Swiss plates treating it as a corridor. The Lesce exit, 20 kilometres after the tunnel, is 10 minutes from Bled. Ljubljana’s old town is just off the ring road, and the dragons on its bridge are the city’s emblem: the Argonauts supposedly killed one here on the way home with the Golden Fleece. One night splits the longest day of the drive in two.

Slovenia is on the Europe plan, which carries on through Croatia and Serbia to North Macedonia and Albania. It is not on the Balkans plan, and the Europe plan stops at the Kosovo border, so the road to Prishtina takes a little planning: an EU SIM to the Serbian border and a Balkans package from there, or both packages on one eSIM. The guide goes through it border by border, vignettes and queues included.

Reading about Slovenia

Slovenia questions.

Answers about data, coverage and setup for Slovenia.

No. Slovenia is on the Europe plan only; the Balkans plan starts at the Croatian border. On the drive to Kosovo that matters twice: the Europe plan covers every country from Germany to Serbia, North Macedonia and Albania but not Kosovo, and the Balkans plan covers Kosovo and its neighbours but nothing north of Croatia. Both can sit on the same eSIM, and each package starts where the line first connects in a country on its own list. The Balkans plan
