Unlock Top Value: Data Sizes & Smart Buys
We break down the costs so you can make an informed decision. For example, a 5GB plan for 15 days might seem sufficient, but often, a 10GB plan for the same duration offers a significantly better price per gigabyte. Always check the $/GB to find the true bargain. No hidden fees, just honest comparisons to help you pick the smartest buy for your data needs.

This specific plan is valid only within Czechia (or, if it's a regional plan, you'd say "Yes"). This is the most important question for "Euro-trip" travelers. If you take a train from Prague to Berlin (Germany), Vienna (Austria), or Krakow (Poland), your connection will stop at the border. For a seamless multi-country trip, we highly recommend our Europe Regional eSIM, which covers all these countries with one plan.
It depends. Czechia is in the EU, so "Roam Like at Home" applies only to EU citizens.
- If you are from the UK (Post-Brexit): Most UK carriers (like O2, Vodafone, Three) have reintroduced daily roaming fees (e.g., £2-£6 per day).
- If you are from the USA/Canada/Asia: Your home carrier will charge expensive international rates (e.g., $10-$14 per day).
A eSIMBuy eSIM is a one-time prepaid fee that is significantly cheaper than these roaming charges.
Yes, 100%. Buying a physical "prepaid" SIM at Prague Airport (from Vodafone, O2, etc.) requires you to find the kiosk, wait in line, and go through a mandatory passport registration process as required by EU law. Our eSIM is 100% digital, requires no ID registration, and can be installed before you fly, so you are connected the moment you land.
To give you the best speed and coverage, our eSIM connects to Czechia’s premium Tier-1 networks, typically O2, T-Mobile, or Vodafone. This ensures you get the fastest available 4G/LTE (and 5G) speeds, whether you are in Prague, Brno, or Český Krumlov.
Yes, absolutely. Czechia has an excellent, modern network. You will have a strong signal on the RegioJet or České dráhy (CD) trains between cities. Crucially, you will also have a continuous 4G/5G signal inside the Prague Metro (subway) stations and tunnels, allowing you to use Google Maps or Bolt (ride-hailing) without interruption.
Most modern phones do, but you must check our specific list here: eSIM Compatible Devices to be 100% sure before purchasing.
Yes. Bolt and Uber are the most reliable ways to get around Prague, and you need active data to book rides and avoid street taxi scams.
Yes. Coverage is excellent in the medieval town of Cesky Krumlov, allowing you to share photos of the castle and river instantly.
Yes. To buy and activate public transport tickets via the official PID Lítačka app in Prague, you need a working internet connection.
