Frequently Asked Questions
What is the cheapest eSIM for Slovenia?
Slovenia is covered by multi-country plans only, and the cheapest is $3.49 for 2 GB, valid for 15 days. Prices come live from 7 vetted providers and change often; the price on this page is the current one.
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 networks do Slovenia eSIMs use?
Slovenia eSIMs on MobiMatter run on Telemach, A1, Mobitel, and T-2; 5G plans are available on Telemach, A1, and Mobitel. Telemach carries the most plans. Each plan names its network, so you choose your carrier before you buy.
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 $0.67 per GB, with 30 GB for 15 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 28 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.

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.

I had a problem because I accidentally activated the wrong eSIM and couldn’t understand why my data wasn’t working. I contacted support, and they figured out the issue right away. They explained everything clearly and stayed helpful throughout the whole process. Their customer support is honestly 10/10—fast, friendly, and very knowledgeable. Everything worked perfectly once I activated the correct eSIM. Highly recommend both the service and the support team. Thank you!
