Where your free eSIM works in Czechia

Strong 4G/5G across the cities and neighbourhoods most travellers actually visit.

  • Prague

    Metro DAS rollout completed in 2022 — 4G runs through all three lines; older Line A stretches drop briefly with reconnection within a station or two.

    • Staré Město
    • Malá Strana
    • Vinohrady
    • Žižkov
    • Karlín

  • Český Krumlov

    Patchy in the centre — the river bend + steep hills cause side-street dead spots. Pre-download offline maps for the day trip from Prague.

    • Old Town
    • Latrán
    • Castle

  • Brno

    Capital of Moravia; full 5G across the centre + Špilberk Castle. Cheaper beer than Prague, fewer tourists.

    • Centre
    • Brno-střed
    • Špilberk

  • Karlovy Vary

    Spa town with 5G along the colonnades; signal dips in the surrounding hills where the open-air baths sit.

    • Colonnade
    • Vřídelní
    • Drahovice

What to install before you land in Czechia

The eSIM gets you online — these are the local apps it unlocks the moment you arrive.

  • ČD Můj vlak

    Czech Railways app — IC + EC + regional tickets. The Prague–Brno corridor is fully covered with 5G trackside.

  • PID Lítačka

    Official Prague transit app: metro + tram + bus + Vltava ferries on one ticket. The 24-hour pass beats single rides.

  • Bolt / Liftago

    Bolt is dominant; Liftago is the local licensed-taxi alternative with marked vehicles — useful for late-night Wenceslas Square.

  • Mapy.cz

    Czech-built map app with the best Sudety + Šumava trail coverage. Pre-cache before remote hikes.

Local prepaid SIM vs. our free eSIM in Czechia

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

Local prepaid SIM
Vodafone CZ prepaid
499 Kč· 10 GB
ID required — Photo ID scan at any O2 or Vodafone shop under the 2022 anti-fraud law.

Generous data, but the ID scan + shop detour is the real cost. The free eSIM bypasses it.

Free eSIM for Czechia FAQs by co:sim

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

Does the free eSIM work in the Prague Metro?
Yes, on all three lines. DAS rollout completed in 2022 — 4G runs through every tunnel. Brief drops on the oldest Line A stretches, reconnection within a station or two.
Does it work in Český Krumlov?
Yes in the centre + at the castle. The river bend + steep hills cause patchy side-street coverage. Toggling airplane mode can force a tower handover; offline maps are safer for the side streets.
Can I use it on trains crossing into Austria or Germany?
Yes. Coverage holds along the Prague–Brno + Prague–Ostrava corridors with only brief drops in the Děčín tunnels on the Prague–Berlin route. At borders the operator name changes automatically.
Will my phone need to register under the Czech anti-fraud law?
No. The registration requirement applies only to physical SIMs sold inside Czechia. An internationally issued eSIM profile is exempt.
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.
