Slovenia travel data eSIM
What is a Slovenia eSIM?
Keep your phone connected while exploring Slovenia’s diverse landscapes, from the Alpine peaks of the Julian Alps to the coastal stretch near Koper. This data-only eSIM installs via QR code before your trip. It activates only when you first connect to a local network in Slovenia, ensuring your validity period begins exactly when you arrive. Ideal for navigating Ljubljana streets or checking train times to Lake Bled without relying on hotel Wi-Fi or expensive roaming charges.
Your eSIM connects to Telemach 5G or Mobitel 5G networks. The plan provides a set amount of data valid for a specific duration, starting from your first connection in the country. You choose a data tier based on your expected usage, whether for quick navigation or heavier streaming. The connection remains active throughout the validity period as long as you stay within the network’s reach.

Local networks
Which networks you connect to in Slovenia
The eSIM links to Telemach 5G and Mobitel 5G infrastructure. Network availability varies by location, so your experience depends on the operator’s presence where you are. Urban centers like Ljubljana and Maribor typically have strong infrastructure, while remote mountainous areas may have different network conditions. Always check local network maps for specific regions you plan to visit to understand potential availability.

Questions people actually ask
If yours is not here, write to us — we answer within 24 hours.
Which networks does the Slovenia eSIM use?
It connects to Telemach 5G and Mobitel 5G. This means you access local infrastructure rather than international roaming. Your device links to whichever network is available at your specific location within the country, providing direct local data access.
Does this work in neighboring countries?
No, this is a single-country plan valid only in Slovenia. It will not connect in Italy, Austria, Hungary, or Croatia. For trips spanning multiple borders, look for regional plans that include those specific neighboring countries in their validity area.
Which plan size fits a trip to Ljubljana and Bled?
As a rough guide, the 3GB or 5GB options often suit short city breaks. The 10GB or 20GB plans offer more buffer for heavier data use like streaming or large map downloads during your stay in these two popular destinations.
Will I lose my own phone number?
No. Your physical SIM stays in the phone and keeps your number for calls and WhatsApp. The eSIM only carries data, so both work side by side.
When does my plan start counting down?
When the eSIM first connects to a network at your destination — not when you buy it. So you can install it days before you fly without losing any time.
Is my phone compatible?
Most phones from 2018 onwards are: iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later. Your phone also has to be carrier-unlocked. Dial *#06# — if an EID appears, you have eSIM. Full list on our Device Compatibility page.
How fast will I get my QR code?
Usually within a couple of minutes of payment, by email. If it has not arrived, check spam first, then write to us and we will resend it immediately.
Can I use hotspot or tethering?
Yes, on every plan we sell. Share the connection with a laptop, a tablet or the rest of your group.
What if I change my mind?
If you have not installed the eSIM, you get a full refund within 180 days. Once a profile is activated and data has been used it cannot be refunded — the allowance is consumed from the network. Full detail in our Refund Policy.
Do you sell plans for groups?
Yes. For Umrah and Hajj groups, student trips and tour operators we deliver the QR codes as a single batch before departure, at group rates. Email us with your group size and destination.
