My recommendation

Traveltomtom recommends an A1 sim card for Slovenia. A1 has very good 4G/5G network coverage in Slovenia and a good prepaid sim card plans for tourists. For $11 USD you get about 7 GB data.

It leaves no doubt Traveltomtom recommends e-sim cards over physical prepaid sim cards when traveling to Slovenia in 2024. E-sim cards make the whole process so easy and there is no time wasting buying a prepaid sim card for tourists on arrival in Slovenia. For $23.90 USD you get 15 GB data in all of Europe + unlimited calls.

Traveltomtom recommends ordering an e-sim card for Slovenia via either Airalo or SimOptions.

Make sure your phone is e-sim compatible before ordering an e-sim card for Slovenia.

With an e-sim card you keep your own phone number from home, but make sure your phone is unlocked and e-sim compatible.

There is another e-sim provider tested and reviewed by Traveltomtom and although they sometimes have great e-sim card deals for Slovenia it is not Traveltomtom's first recommendation. Personally I have faced some issues with Nomad e-sim cards and unless they are not improving on reliability and performance Traveltomtom is not recommending Nomad e-sim cards over Airalo and SimOptions.

If your phone is not e-sim compatible then there still is the option to order a physical prepaid sim card for Slovenia on the internet. This physical prepaid sim card will be delivered to your home address before your trip to Slovenia.

There are pre-activated international sim cards for $24.90 USD with 10 GB data and unlimited calls/text in all of Europe. Check out SimOptions to order a physical prepaid sim card for Slovenia.

Slovenia prepaid sim cards and EU data roaming

Throughout this article you will find out that Slovenia sim cards are NOT the best for traveling in Europe. All the prepaid sim cards you can buy in Slovenia have no or very limited EU data roaming included in their data packages. That means if you buy a sim card in Slovenia and you travel onwards to Italy you have very limited data available and it is better to buy a new sim card in Italy.

However, if you are visiting multiple countries in Europe you are better choosing a sim card from Traveltomtom's comparison of the best prepaid and e-sim cards for traveling in Europe in 2024.

Mobile internet operators in Slovenia

There are actually 4 mobile internet operators in Slovenia and for such a small country that is a lot:

  • Telekom Slovenia
  • Telemach Slovenia
  • A1 Slovenia
  • T2

T2 does not have Slovenia prepaid sim cards. Therefore this research for finding the best Slovenia prepaid sim card is focussed on Telekom, Telemach and A1.

Best 4G/5G Slovenia network in 2024

In 2024 all tourist destinations in Slovenia are covered with a 4G/LTE phone signal and even a 5G signal. There is however a difference in the 4G/5G network of Telemach, A1 and Telekom, so Traveltomtom compared the 4G/5G coverage maps of Slovenia below to show you which provider has the best mobile data network in Slovenia.

Is there 5G in Slovenia?

Yes, there is 5G in Slovenia however, it is mostly concentrated around Ljubljana and Maribor at the moment.

Telekom Slovenia 4G/5G network coverage map

tmobile 4g 5g network coverage map slovenia 2024

Telemach Slovenia 4G/5G network coverage map

telemach 4g 5g network coverage map slovenia 2024

Although the above mobile data network coverage maps are updated for 2024 they are not 100% accurate. However, they are a great reference to compare the 4G/5G networks of the mobile internet providers in Slovenia in 2024.

From the updated Slovenia 4G/5G network coverage maps Traveltomtom comes to the conclusion that Telemach has a much weaker 4G/5G mobile data network compared to Telekom and A1.

Therefore a Telemach prepaid sim card is not Traveltomtom's first recommendation.

A1 has the best 5G network in Slovenia in 2024, but Telekom has the most extensive 4G/5G mobile data network in Slovenia in 2024.

Where to buy a Slovenia prepaid sim card

telekom slovenia shop

Ljubljana Airport

On arrival at the airport would of course be the most convenient place to buy a prepaid sim card for Slovenia. However, there are hardly any intercontinental flights arriving in Ljubljana and most European travelers don't buy prepaid sim cards anymore.

I guess that is why there is no sim card shop at Ljubljana Airport.

Phone stores city center

When you get to Ljubljana city center there are multiple mobile phone shops. Type in the by you preferred mobile operator on Google Maps and locsate the nearest one near your hotel. Ljubljana is a small city, you can easily walk everywhere. There are A1, Telekom and Telemach stores in all big cities and popular tourist destinations in Slovenia.

Unlike almost any other European country in Slovenia you do NOT need to bring a passport when buying a prepaid Slovenia sim card.

Convenience stores in Slovenia

You can also buy your sim card for Slovenia in the well known convenience stores, supermarkets and gas stations like Petrol, Big Bang, Harvey Norman, Mercator and Posta Slovenije. This is not Traveltomtom's first recommendation, but it works. Obviously the staff of these convenience stores or gas station have obviously no knowledge of these prepaid sim cards.

You can only buy set prepaid sim card packages and you will have to do the activation yourself.

Online

As I mentioned before, ordering a sim card for Slovenia on the internet is actually the easiest way to stay connected and avoid high roaming costs. No more visiting a sim card shop on arrival in Slovenia.

The fastest way is an e-sim card for Slovenia, it takes just a couple clicks and as soon as the plane lands you are connected to the internet and have data on your phone. Traveltomtom recommends ordering an e-sim card for Slovenia from either Airalo or SimOptions.

If your phone is not e-sim compatible then look into ordering an international prepaid sim cards that will be delivered to your home address. Check out SimOptions for ordering a physical prepaid sim card for Sloveniaordering a physical prepaid sim card for Slovenia.

Best Slovenia prepaid sim card in 2024

Comparing all the Slovenia prepaid sim card deals Traveltomtom comes to the following conclusions:

  • Telemach Slovenia prepaid sim cards are very flexible.
  • The 4G/5G network of Telemach is much smaller/weaker than A1 and Telekom.
  • Telemach allows limited EU data roaming, Telekom and A1 do NOT allow EU roaming at all.

All in all Traveltomtom rates A1 as the best prepaid sim card for Slovenia in 2024.

A1 has some good prepaid sim card plans for tourists and A1 has the best 4G/5G mobile data network in Slovenia. For $11 USD you get 7 GB data with an A1 prepaid sim card.

Comparing the Slovenia prepaid sim cards with e-sim cards for Slovenia you order on the internet we see that e-sim cards are a couple dollar more expensive, but the convenience is that you are online and have data on your phone as soon as the plane lands. No more wasting time finding a sim card shop in Slovenia.

The best buy e-sim card for Slovenia is a Bouygues Telecom e-sim with 15 GB data in all of Europe + unlimited calls for $23.90 USD Traveltomtom recommends ordering an e-sim card for Slovenia via either Airalo or SimOptions.

If you are traveling onwards in Europe then Slovenia sim cards are an absolute no-go because of their EU data roaming limitations! Traveltomtom put together a list of the best prepaid and e-sim cards for Europe travel in 2024.
