ID required — Telekom Slovenije, A1 + Telemach require passport registration at retail stores under early-adopted EU SIM KYC rules.

Same quota as our free plan, but €12 + a Ljubljana detour. The eSIM activates at LJU.

Free eSIM for Slovenia FAQs by co:sim

Everything you need to know about the free new-user eSIM offer.

Does the eSIM work around Lake Bled?
Yes — dense 4G/5G covers the full shoreline, the pletna boats, Bled Castle + Vintgar Gorge. Telekom Slovenije added dedicated cells for tourist volume.
Can I use it on the Postojna Cave train?
Partially. The entry hall has Wi-Fi + cellular, but signal drops once the train enters the cave and resumes at the exit. No carrier works underground.
Will it work crossing into Italy, Austria or Croatia?
Yes. All three are in the EU33 pool. Fernetti, the Karavanke tunnel + Obrežje all hand off automatically on the same plan.
How is coverage at the Soča valley + Bovec?
Bovec town + Kobarid have full 4G. The Soča gorge itself thins out — top up inside the app from town if you blow through your quota.
Who's eligible for the free eSIM?
New users who have not previously claimed a free eSIM. Eligibility is verified at checkout.
Will I be charged anything?
$0 is charged for the free eSIM. A valid card is collected at checkout for verification only — this prevents the same person claiming multiple free eSIMs. You only pay if you choose to top up later.
How long is the free eSIM valid?
Install and activate the eSIM within 30 days after purchase. Once activated, the free plan is valid for 7 days from your first connection. After that, top up anytime to extend the validity — the same eSIM keeps working.
Can I top up or buy more data after?
Yes. Top up the same eSIM with any paid plan at any time — your data and validity extend instantly, no reinstall required. You can also buy plans for any of our 190+ other destinations.
Can I claim the free eSIM again?
No. This free eSIM is a new-user offer, so it can only be claimed once.
How does the free plan compare to paid plans?
Same high-quality network coverage. Paid plans offer more data and longer validity — and you can top up onto your free eSIM at any time.
