Is it worth getting an eSIM for Slovenia?
For most travellers, yes, if your phone supports eSIM. Slovenia plans start at $3.49 for 2 GB, and the longest lasts 365 days, which suits long stays and repeat visits. If your home plan already covers Slovenia at no extra cost, you may not need one.

Which eSIM is best for Slovenia?
No plan covers Slovenia alone right now, so the choice is a multi-country plan. The top one is 120 GB for 30 days at $49.99 from Bouygues, covering 34 countries. We rank plans on quality and value for money. If price per GB is all that matters, the lowest right now is $0.77 per GB, with 35 GB for 30 days.
How much data do I need for a week in Slovenia?
It depends on how you use your phone. Light use (maps, messaging, browsing) takes about 0.5–1 GB a day; scrolling a lot of social video can take 2–3 GB or more. Typical use per hour:
- Instagram Reels, TikTok: 0.3–1 GB
- YouTube, Netflix at standard quality: 0.5–1 GB
- Video calls (WhatsApp, FaceTime): 0.5–1 GB
- Voice calls (WhatsApp, FaceTime Audio): 50–70 MB
- Maps and navigation: 2–6 MB
- Messaging and browsing: 50–150 MB
The cheapest Slovenia plan with at least 5 GB for a week or longer is 5 GB for 30 days at $6.49.
Is there an unlimited data eSIM for Slovenia?
Yes. Unlimited data plans for Slovenia start at $7.99. Many unlimited plans slow down after a daily high-speed allowance, so check the fair-use terms on the plan page before you buy.
Do Slovenia eSIMs support 5G and hotspot?
5G is available on 25 plans for Slovenia, where the local network has 5G coverage; the others use 4G/LTE. Hotspot (tethering) works on every plan, so you can share your data with other devices.
Does a Slovenia eSIM come with a phone number?
Most travel eSIMs, including most Slovenia plans, are data-only and have no local number. You keep your usual number on your main SIM for calls, texts and WhatsApp. Plans that include a number or minutes say so on the plan page.
Will my phone work with a Slovenia eSIM?
Yes, if it supports eSIM and is not locked to a carrier. To check, dial *#06#: if an EID number appears, your phone supports eSIM. Most iPhones from the XS/XR on, Galaxy S20 and later and Pixel 3 and later do, except most models sold in mainland China and some sold in Hong Kong and Macao.
Can I keep my own SIM and WhatsApp while using a Slovenia eSIM?
Yes. Your eSIM and your main SIM can be active at the same time. Use the eSIM for mobile data with data roaming on for that line, and turn data roaming off on your home SIM to avoid charges. WhatsApp keeps working on your usual number.

What our customers say
5.0
I loved it! I can have data wherever I go, they have many options, the data lasts a long time and is very affordable. I used the 3GB option for Europe and I've already had data for 15 days for €5. Honestly, if you manage it well and use it only when you don't have Wi-Fi, it can easily last you thirty days. I still have 1.6 GB left (half) and I have 10 days left on the plan. Highly recommended app for eSIM 💪

I have been using it for about 2 years and I am very satisfied. I used it in Greece, Bulgaria, and Romania, and I experienced internet speeds that I haven't seen in Turkey.

very convenient app to buy an eSim for travelling, you can choose the countries you need and have it in one pack, you can filter the options by the GB space and sort it by price, so it takes less time then just manually comparing different eSim apps. Local 5G internet works well

I used it in Italy in 2024 and in Spain in 2026, and I was very satisfied. The app has improved day by day, and I never experienced any issues. I don't know about other apps, but I highly recommend MobiMatter. I bought 15GB of internet in Spain, and even though I didn't use that much, I still have 10GB left.
