Cheapest eSIM for Slovenia: the numbers
As of 31 August 2026, 15:21 GMT, the cheapest eSIM for Slovenia is eSIMCard with 100 GB for 31 Days at $35.41. That is $0.35 per GB, the best rate of the 167 plans we compare from 9 providers. 116 plans include 5G. 53 support top ups. That timestamp is the exact moment of our latest price check, and the table above always shows the live order.
Which mobile networks does Slovenia have?
4G covers about 98% of the population on both Telekom Slovenije and A1, and by 2025 5G already accounted for 43.8% of Slovenian mobile lines.
- Telekom Slovenije: Telekom Slovenije leads the mobile market with 36.85% of active users in 2025 and wins Opensignal's 4G coverage award, with 5G open to prepaid customers since April 2024.
- A1 Slovenija: A1, part of Telekom Austria Group, is second with 25.45% of users and 4G coverage on par with Telekom at about 98% of the population.
- Telemach: Telemach, owned by United Group, holds 24.74% of users and leads the country on 5G, with 98.3% 5G availability and average 5G downloads around 300 Mbps in Opensignal testing.
- T-2: T-2 is the small fourth operator, now under the Telemach and United Group umbrella, and scored 92.5% on 5G availability in Opensignal testing.
Budget brand HoT sells cheap prepaid packs and is a popular low cost alternative, though most travel eSIMs connect through the three main networks.
The eSIM plans we compare on this page connect to:
Is 5G available in Slovenia?
All the main operators run 5G. Telemach leads on availability and speed, and coverage is strongest in Ljubljana, Maribor and the other larger towns.
How much data do you need in Slovenia?
Light use is about 500 MB a day. That covers maps, messages, and some browsing. Normal use with photos, social apps, and short videos runs 1 to 1.5 GB a day. Streaming and hotspot use can eat 2 to 3 GB a day. Here is what each size costs in Slovenia right now:
Are unlimited eSIMs for Slovenia really unlimited?
Not always. 29 of the plans above are sold as unlimited. Most unlimited travel plans have a fair use rule. You get full speed for a daily amount, often 1 to 5 GB, then the speed drops to around 1 Mbps until the next day. That is fine for messages and maps but slow for video. If you know how much data you use, a fixed plan with a low price per GB is usually the better deal. That is why we rank by price per GB and not by labels.
eSIM or a local SIM at the airport in Slovenia?
An eSIM is ready before you land. No queue, no shop, no handing over your passport at a counter. Data for Slovenia starts at $35.41 on this page, which is hard for airport kiosks to beat. A local SIM still makes sense if you need a local phone number or plan to stay for months. For a normal trip, the eSIM wins on price and effort.
Setting up your Slovenia eSIM
Buy your planYou get a QR code by email within minutes of paying.
Install before you flyScan the QR code on wifi at home. Airport and hotel wifi can be weak.
Turn it on when you landEnable the eSIM and turn on data roaming for it, then give it a minute to find the network.
Check the validity clockSome plans start counting at purchase, not at first use. Check before you buy.
Good to know before you land in Slovenia
Both Telekom Slovenije and A1 have switched off 3G, so bring a 4G capable phone. Slovenian prepaid SIMs mostly block or restrict EU roaming unless you register a Slovenian address and tax number, so do not buy one as a regional travel SIM.
There is no big tourist SIM counter scene documented at Ljubljana airport. Prepaid SIMs are easy to find at operator stores, post offices and petrol stations, for example Telekom's Mobi SIM at 8.50 euros with 5 euros of credit.
EU and EEA visitors can simply roam at domestic rates, which is the easiest option for a short stay. If you buy local, Telemach is the pick for 5G speed and Telekom for rural 4G coverage.

Do Slovenia eSIMs support 5G?
116 of the 167 plans we track for Slovenia include 5G where the local network offers it. The rest run on 4G, which is still fine for maps, calls over apps, and video.
Can I top up my Slovenia eSIM if I run out?
Yes. 53 of the 167 plans here support top ups, so you can add data without buying a new eSIM. The rest need a fresh plan once the data ends.
Will I still receive bank SMS and OTP codes?
Yes, if you keep your home SIM active. Travel eSIMs are data only. Your phone can hold both at once, so leave your normal SIM on for SMS and use the eSIM for data. Turn off roaming data on the home SIM to avoid charges.
Do these eSIMs include a phone number or calls?
The plans we compare are data only, so there is no local number. Calls work fine over WhatsApp, FaceTime, or any app that uses data. If you need a real local number, a local SIM is the better tool.
How many GB do I need for a week in Slovenia?
Around 3 to 5 GB covers a week of maps, messaging, and normal browsing. Heavy video or hotspot use needs 1 to 2 GB per day. Today the cheapest plan with at least 5 GB is MegaEsim at $2.87.
