Czech law does not require prepaid SIMs to be registered against a document, so you can buy one anonymously and use it immediately. Vodafone's CZK 349 Tourist SIM covers a week of unlimited data; T-Mobile's CZK 299 15 GB eSIM is better value for a longer stay.
- No registration and no paperwork. Czech law does not require prepaid SIMs to be tied to a document, so you buy one with cash or card and it works immediately.
- Up to a week, the Vodafone Tourist SIM at CZK 349 gives unlimited data capped at 10 Mb/s plus CZK 100 of credit.
- For one to four weeks, the T-Mobile Twist 15 GB eSIM at CZK 299 is the best price-to-data ratio and activates entirely online without visiting a store.
- Physical SIMs are on sale as soon as you clear customs, at the Relay newsagents in both Prague airport terminals - check the printed price, because independent kiosks charge above it.
- In the city, use official operator stores on Václavské náměstí, Národní or in Palladium rather than a tourist kiosk.
What to buy as soon as you land
No registration, no paperwork. Czech law does not require prepaid SIM cards to be registered against an identity document, so you can buy one anonymously with cash or card and activate it immediately by inserting it or scanning an eSIM QR code. Coverage is a mature 4G/LTE and 5G network.
- If your phone takes an eSIM, buy the profile online before you fly or over the airport Wi-Fi - the T-Mobile 15 GB package at CZK 299, for instance, or a Saily profile if you would rather not deal with a Czech operator at all.
- If not, physical SIMs are on sale as soon as you clear customs at the airport.
