Our honest tip: If your phone supports eSIM, install one at home before you fly. You land at Ljubljana airport, switch it on, and you can book your transfer, open maps and message your host before you reach the baggage belt.

Slovenia is in the EU, so “Roam like at home” applies: calls, texts and data cost the same as at home. However, your operator’s fair-use data limits may still apply. The rule is extended until 2032 and covers all 27 EU countries plus Iceland, Liechtenstein and Norway (European Commission).

Three things locals know that visitors often don’t:

• The UK is not included any more. Since Brexit, UK operators may charge for roaming in Slovenia. Some include Europe, many charge a daily fee – check before you go.
• Switzerland and the Western Balkans are outside the EU too. If you’re doing a Balkan road trip (Slovenia → Croatia → Bosnia → Montenegro), your EU SIM is free in Slovenia and Croatia but can get expensive across the border. A regional Europe + Balkans eSIM solves that.
• “Unlimited” plans may have a data limit when used abroad. On very cheap unlimited plans your operator can limit how many GB you get at EU prices. For a normal holiday you won’t notice.

An eSIM is a digital SIM you download to your phone – no plastic card, no shop, no queue. You buy a data plan online, scan a QR code, and it connects to a Slovenian network when you arrive. You can usually keep your regular SIM active for calls and text messages while using the travel eSIM for mobile data. Check your phone’s dual-SIM settings and your home operator’s roaming charges. 

Why we recommend it to our guests:

• You’re online at the airport, on the bus, in your taxi – before you find Wi-Fi.
• Plans for Slovenia start at a few euros for 1-3 GB, enough for a city break with maps, messages and photos.
• If you continue to Croatia, Italy or Austria, a Europe plan covers all of it with one eSIM.
• No passport registration, no Slovenian-language menus.

How to set it up (5 minutes):

1. Check your phone supports eSIM. Most recent iPhone, Google Pixel and Samsung Galaxy models support eSIM, but compatibility varies by model and region. Check your phone manufacturer’s specifications and make sure your device is carrier-unlocked before purchasing an eSIM. 
2. Buy the plan at home while on Wi-Fi and install it via the QR code.
3. Leave it switched off until you land; then turn it on and enable data roaming for the eSIM line.
4. Set the eSIM as your mobile-data line and keep your home SIM for calls/SMS.

We recommend it because it runs on Slovenian networks with 5G in the cities, installs in minutes and has 24/7 chat support. If you book through this link, ljubljana.info earns a small commission at no extra cost to you – it helps keep this guide free.

When an eSIM is not worth it: if you have an EU SIM, or you’re only in Ljubljana for a few hours and happy with café Wi-Fi.

A Slovenian prepaid SIM is the cheapest option per GB if you stay several weeks or need a local number. For a short trip it’s usually more hassle than it’s worth: you need to find a shop, swap the physical SIM (and keep your home SIM safe somewhere), and some menus and texts from the operator are in Slovenian.

Slovenia has three main operators, all with good coverage and prepaid packages:

Where to buy in Ljubljana: operator shops in the centre around Trg Ajdovscina / Slovenska cesta, shopping centres (BTC City, Citypark), plus starter packs at post offices, petrol stations and kiosks. Bring your passport in case the seller asks for it.

Our local tip: starter packs come with a small credit; you then activate a data package by text or in the operator’s app. If you don’t speak Slovenian, ask the shop staff to activate the package for you before you leave – they’re happy to do it, and it saves you 20 minutes of guessing.

Prices and packages change often – check the operator’s website before buying.

Ljubljana runs a free city Wi-Fi network called WiFree Ljubljana, covering the old town, the riverbanks, Preseren Square, Congress Square and the main streets. Coverage is not available throughout the entire city, so don’t rely on WiFree as your only source of internet access. It’s free to use in sessions of up to three hours, and you can start a new session when one runs out. 

How to connect:

1. Select the network WiFreeLjubljana on your phone.
2. A login page opens (if not, open any website in your browser).
3. Accept the terms and follow the steps on screen.
4. You’re online – when the session ends, simply log in again.

What it’s good for: maps, messages, checking the bus timetable, uploading a few photos.
What it’s not good for: video calls on the move, anything sensitive (it’s an open public network), and anywhere outside the centre.

WiFree support: +386 41 300 200.

We have noticed that the signal is strongest in the open squares and along the Ljubljanica riverbanks; inside old stone buildings and the castle hill paths it drops. Avoid entering sensitive information on untrusted public Wi-Fi networks. Make sure websites use HTTPS and keep your phone and apps updated. For sensitive activities, use your mobile data connection when possible. 

Many hotels, hostels, apartments, cafés, bars and restaurants in Ljubljana offer free Wi-Fi to their guests. The network is usually password-protected; the password is often printed on the menu, on the receipt, on a little sign by the bar –  or just ask the waiter: “Kakšno je geslo za Wi-Fi?” (KAHK-shno yeh GEH-slo za Wi-Fi). Locals will smile. Learn more basic Slovenian words and phrases.

Local tips from a guide:

• Cafés are made for lingering and enjoying your time. In Ljubljana nobody rushes you out after one coffee. Ordering a kava and working for an hour by the river is completely normal.
• Best spots to sit and get online: the cafés along the Ljubljanica embankments (Cankarjevo and Breg), or the Central Market area for more local vibe. See our favourite bars & cafés.
• Hotel Wi-Fi is usually fast and free.
• Libraries and museums often have free Wi-Fi for visitors – handy on a rainy day.
• Buses: don’t count on Wi-Fi on city buses or regional coaches; it exists on some lines but isn’t reliable. This is exactly where mobile data (or an eSIM) makes the difference.

Mobile internet is useful for much more than browsing social media. Here are five real-life situations where having a working data connection can make travelling around Slovenia easier:

1. Arriving at Ljubljana Airport

You’ve just landed at Ljubljana Airport and need to contact your transfer driver, confirm your pickup location or let your accommodation know when you’ll arrive. Having mobile internet as soon as you land makes this much easier.

2. Finding Your Apartment in Ljubljana

You’re walking through the city with your luggage and need Google Maps to find your apartment, check the entrance location or contact your host. A mobile data connection helps you navigate without relying on public Wi-Fi.

3. Sharing Internet with Your Family

Travelling with your partner or children? If your eSIM supports hotspot sharing, one person can share their mobile data connection with other family members. This can be a practical alternative to buying a separate data plan for every phone.

4. Exploring Slovenia Beyond Ljubljana

Whether you’re visiting Lake Bled, Postojna Cave, Piran or the Soca Valley, mobile internet helps you navigate, check directions, find parking, look up opening times and stay in touch while travelling. Coverage can vary in remote areas, so downloading offline maps in advance is still a good idea.

5. Meeting Your Tour Guide

You’ve booked a walking tour, bicycle tour or day trip and need to find your guide at the meeting point. With mobile internet, you can check the exact location on Google Maps, contact your guide via WhatsApp or Viber if you are running late, and receive last-minute updates. This is especially useful in busy areas such as Preseren Square, the Triple Bridge or Ljubljana Castle.

Yes. Mobile internet coverage in Slovenia is generally good in cities, towns and along major roads. All three main mobile operators – Telekom Slovenije, A1 Slovenija and Telemach – provide coverage across much of the country. However, the signal can be weaker or unavailable in remote mountain areas, deep valleys and some rural locations.

If you are planning to visit Bled, Bohinj, Piran, Postojna Cave or the Soca Valley, you will generally have mobile internet access in populated areas and along main routes. For hiking in the Julian Alps or travelling through remote areas, download offline maps before you go.

You can check network availability in specific locations using the official AKOS coverage map.

We recommend:

• Download offline maps (Google Maps or Maps.me) of Slovenia before you leave the city.
• Driving? You’ll need data for navigation, the DARS highway vignette check and parking apps. A local SIM or eSIM with 5 GB+ is worth it.
• Hiking in the Julian Alps: don’t rely on coverage alone. Save the emergency number 112. If your own mobile operator has no signal, your phone may still be able to connect to another available network for an emergency call. However, if there is no mobile network coverage at all, you may not be able to make a call. Download offline maps before hiking in remote mountain areas. About emergency number 112 on Slovenian government website.
• Continuing to Croatia or Italy? Pick a Europe eSIM plan instead of a Slovenia-only plan so you don’t need a second one at the border.

Is there free Wi-Fi in Ljubljana? Yes. The city network WiFree Ljubljana covers the city centre and is free in sessions of up to three hours, which you can renew. Almost all cafés, restaurants, hotels and hostels also offer free Wi-Fi to guests.

Do I need an eSIM in Slovenia if I have an EU SIM? No. Slovenia is in the EU, so ‘Roam like at home’ applies until 2032 – you pay the same as at home. This also covers Iceland, Liechtenstein and Norway, but not the UK or Switzerland.

What is the best eSIM for Slovenia? One that uses Slovenian networks with 4G/5G, lets you top up and has live support. For a city break 1-3 GB is enough; for a week of driving around Slovenia take 5-10 GB. If you continue to Croatia, Italy or Austria, choose a Europe plan. The eSIM I recommend.

eSIM or local SIM card – which is cheaper? For stays under about two weeks, an eSIM is usually the better deal once you count the time spent finding a shop. For longer stays, or if you need a Slovenian phone number, a local prepaid SIM is cheaper per GB.

Can I buy a SIM card at Ljubljana Airport? Options at the airport are limited and usually pricier than in town. The easiest is to install an eSIM before your flight, or buy a SIM in an operator shop in Ljubljana city centre.

Will my phone work with an eSIM? Most recent iPhones, Google Pixels and Samsung Galaxy phones support eSIM. Your phone must be carrier-unlocked. Check in Settings → Mobile/Cellular → ‘Add eSIM’.

Will I keep my own phone number with an eSIM? Yes. The travel eSIM handles data; your normal SIM stays active for calls and texts like bank verification codes. Watch out for roaming call charges on your home SIM if you’re from outside the EU.

Is public Wi-Fi in Ljubljana safe? It’s as safe as any open public network. Avoid online banking on it unless you use a VPN, and prefer apps with end-to-end encryption.

Is mobile coverage good outside Ljubljana? Yes. Slovenian networks cover towns, villages, main roads and popular spots like Bled, Bohinj, Piran and Postojna well. In deep Alpine valleys coverage can drop; download offline maps before hiking.

Which mobile operators are there in Slovenia? Telekom Slovenije, A1 Slovenija and Telemach. All three sell prepaid SIM cards.

How do I get internet in Slovenia as a tourist? With an EU SIM you simply use your own plan at no extra cost. From outside the EU, the easiest option is a travel eSIM installed before your trip; alternatives are a Slovenian prepaid SIM card or free Wi-Fi in Ljubljana’s city centre, cafés and hotels.

What is the cheapest way to get mobile data in Slovenia? For EU visitors it’s free roaming. For short trips from outside the EU, a Slovenia or Europe eSIM with 1-5 GB costs only a few euros. For stays of several weeks, a local prepaid SIM from Telekom Slovenije, A1 or Telemach is cheapest per GB.

Can I buy a tourist SIM card in Slovenia? Yes. All three operators sell prepaid starter packs in their shops in Ljubljana, and at post offices, petrol stations and kiosks. Bring your passport in case the seller asks for it, and ask staff to activate a data package for you.
