Local prepaid SIM vs. our free eSIM in Slovakia

What you’d pay at the airport SIM kiosk — and what you save by activating the eSIM before you fly.

Local prepaid SIM
Orange Slovakia Prima Tourist
~€10· 4 GB
ID required — Slovak Telekom, Orange, O2 + 4ka all mandate ID registration for prepaid SIMs under enforced EU rules.

Cheap on shelf but the registration form + queue is the actual cost. The eSIM bypasses both.

Free eSIM for Slovakia FAQs by co:sim

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

Does the eSIM work in the High Tatras?
Reliable 4G at lower + mid-elevations like Štrbské Pleso, Hrebienok + the Skalnaté Pleso funicular. Summits above 2,500 m lose signal due to terrain.
Can I cross into Austria, Hungary, Czechia or Poland?
Yes — all four neighbours are in the EU33 pool. The eSIM auto-switches at borders like Bratislava–Vienna + Kúty–Břeclav.
Does it work on the Vienna airport bus to Bratislava?
Yes. RegioJet + FlixBus shuttles cross at Kittsee — the profile hands off from Austria to Slovakia with no signal gap.
How is coverage at Spiš Castle?
Full 4G blankets the entire ruin including the 500m upper courtyard, thanks to a dedicated Slovak Telekom cell installed in 2020. Drone uploads work live.
What about the Slovak Paradise caves?
Underground sites like Dobšinská Ice Cave + Ochtinská Aragonite Cave have no signal inside. Surface cells reach parking lots + visitor centres only.
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.
