Slovenia eSIM for Travel – Instant 4G/5G Data
Instant mobile data in Slovenia from £4.99. No roaming charges. Keep your UK number. Activates the moment you land.
A typical Slovenia itinerary loops Ljubljana, Bled and the Adriatic coast – mobile data ties the whole trip together. TripSIM provides an instant Slovenia eSIM with coverage on Telekom Slovenije, A1 Slovenia, Telemach, so you can land at Ljubljana Jože Pučnik (LJU) and be online before you reach the taxi rank. Direct flights from London to Ljubljana with Wizz Air make Slovenia a long-weekend destination, but EU roaming for Brits is no longer included. No physical SIM swap, no airport kiosks, no surprises on your next UK phone bill.

Slovenia eSIM FAQs
Does an eSIM work in Slovenia?
Yes — TripSIM eSIMs work across Slovenia on local 4G/5G networks (Telekom Slovenije, A1 Slovenia, Telemach). You activate before you fly and it connects automatically when you land.
Can I keep my UK number while using a Slovenia eSIM?
Yes. Your physical UK SIM stays active for calls, texts and WhatsApp. The TripSIM eSIM runs alongside it as a data-only line.
Is hotspot / tethering included?
Yes, every TripSIM plan supports personal hotspot.
When should I install the eSIM?
Install before you leave the UK while on WiFi. Activation only starts when you connect to a local network in Slovenia.
Is TripSIM cheaper than UK carrier roaming in Slovenia?
Almost always. UK carriers typically charge £3–£6 per MB on UK carriers in Slovenia. Save up to 82% vs UK roaming.
Will a TripSIM eSIM work across Slovenia?
Yes. TripSIM connects to Telekom Slovenije, A1 Slovenia, Telemach, which together cover Ljubljana, Bled, Piran and most Slovenia travel destinations. Coverage in rural areas may be more limited – check the coverage map before travelling off the main routes.
How much data do I need for 5 days in Slovenia?
For typical UK-tourist use (maps, messaging, social, occasional video calls), 0.5–1 GB per day is a comfortable allowance. We recommend our mid-tier plans for shorter trips and unlimited for two-week stays.
Is the TripSIM Slovenia eSIM faster than buying a SIM at Ljubljana airport?
Buying a local SIM in Slovenia usually means queueing at an arrivals kiosk, showing your passport, topping up in Euro and configuring APN settings. A TripSIM eSIM is QR-activated before you fly and online the moment your phone connects to a Slovenia network.
Can I make voice calls or send SMS with a TripSIM Slovenia eSIM?
TripSIM is a data-only eSIM. Voice and SMS are not supported – but you can call and message over WhatsApp, FaceTime, Telegram and other internet-based apps as normal. For UK emergency services, your physical SIM remains the appropriate route.
Does the TripSIM Slovenia eSIM work alongside my UK SIM?
Yes. Dual-SIM phones (iPhone XS and later, most modern Androids) can run your UK number for calls/SMS and your TripSIM data plan in parallel. We recommend turning off mobile data on your UK SIM to avoid roaming charges.
