Description
Prague is dense, walkable, and best navigated by a good map app and the PID Litacka transit app — which both need working data. A Blikst Czech Republic eSIM runs on O2 Czech Republic's 4G / 5G network and keeps you online from the moment you land at Vaclav Havel Airport Prague (PRG), arrive into Brno-Turany (BRQ), or step off the EC train from Berlin or Vienna at Praha hlavni nadrazi. No roaming surprise, no SIM kiosk queue, no wrestling with Czech-language activation menus.
Where O2 works best
Prague, Brno, Ostrava, Plzen and Olomouc all have reliable 4G with 5G in the larger cities and expanding along the D1 motorway. The D1 (Prague–Brno) and D5 (Prague–Plzen–Nuremberg border) hold signal end-to-end. Cesky Krumlov, Karlovy Vary, and Kutna Hora are all well covered. Rural Sumava and the Beskid mountains on the Slovak border drop to 4G in the valleys — still fine for maps and messaging. The Prague Metro has patchy signal between stations and stronger reception at each platform, similar to most European metros.
Cost vs. roaming or a local SIM
EU travellers on "roam like home" already have Czech coverage included — check your domestic plan first. For US, UK, and non-EU travellers, home carriers typically charge around $10 per day for Czech Republic roaming. A Blikst multi-day plan runs well under a week of that, and picking up a local O2 prepaid SIM requires a shop visit with passport and a bit of Czech (or patience). The eSIM skips all of it.
Getting connected on arrival
Install the eSIM on home Wi-Fi before you fly — scanning the QR code needs an internet connection. When you land at PRG and switch off airplane mode, the O2 line registers automatically. Turn off data roaming on your home SIM so it doesn't connect to a Czech tower unnoticed. Prague airport is connected to the centre by the 119 bus to Nadrazi Veleslavin (Metro A) or the AE Airport Express to the main station; with the eSIM already live you can buy your PID ticket in the app on the way.
What travellers actually use data for in Czech Republic
- PID Litacka: Prague's official transit app. Tram, metro, bus, and regional train tickets. Much easier than the ticket machines on trams.
- Bolt and Liftago: Ride-hail in Prague and Brno. Liftago is the Czech-grown competitor and is common for airport runs.
- Google Maps and Mapy.cz: Mapy.cz is the Czech-made mapping app locals actually use — better hiking and cycling detail than Google Maps for Sumava, Krkonose, and the Bohemian Paradise rock towns.
- Rekola and Nextbike: Bike share in Prague and Brno. GPS-based, data-reliant.
- Apple Pay and Google Pay: Widely accepted in Prague, less so in smaller towns. Koruna cash still useful in pubs and markets.
- IDOS / CD Jizdni rady: Czech Railways journey planner for inter-city trains to Karlovy Vary, Cesky Krumlov, and cross-border routes.
Plan sizing for typical trips
A long weekend in Prague on 2–3 GB is realistic. A one-week trip taking in Prague, Cesky Krumlov and Kutna Hora fits into 5 GB. Two weeks with Brno, Moravian wine country, Olomouc and a mountain day in the Krkonose sits comfortably in 10 GB. Remote workers staying a month should budget 20 GB, especially if you're working from cafes rather than a single co-working space with reliable Wi-Fi.
Install the profile before you fly, land at PRG already connected, and buy your tram ticket on the way into town. No kiosk, no roaming bill, one QR code for the whole stay.

eSIM FAQ
The Blikst Czech Republic eSIM runs on O2 Czech Republic's network, one of the country's main mobile operators. You get 4G and 5G speeds, with reliable 4G across the country and 5G in the larger cities. Coverage is also expanding along the D1 motorway, so you stay connected whether you're navigating Prague on foot or travelling between cities by car or train.
O2 works best in Prague, Brno, Ostrava, Plzen and Olomouc, with 5G in the larger cities. The D1 (Prague to Brno) and D5 (Prague to Plzen and the Nuremberg border) hold signal end to end, and Cesky Krumlov, Karlovy Vary and Kutna Hora are all well covered. Being honest, rural Sumava and the Beskid mountains near Slovakia drop to 4G in the valleys, and the Prague Metro has patchy signal between stations but stronger reception at each platform.
Right after you buy, you receive a confirmation email with your eSIM details and a QR code. Install the eSIM on home Wi-Fi before you fly, because scanning the code needs an internet connection. Activation is automatic: when you land at Vaclav Havel Airport Prague and switch off airplane mode, the O2 line registers itself. Turn off data roaming on your home SIM so it doesn't quietly connect to a Czech tower in the background.
Most modern smartphones are fully compatible with Blikst eSIMs, though a few exceptions exist, so check our detailed compatibility list to confirm your device works. Your phone must be carrier-unlocked. On an iPhone you can check eSIM support under Settings, General, About, looking for an EID number, and on Android you'll find it in the network settings. If you're unsure, that compatibility list is the quickest way to be certain before you travel.
It depends on your trip. A long weekend in Prague is realistic on 2 to 3 GB. A one-week trip taking in Prague, Cesky Krumlov and Kutna Hora fits into about 5 GB. Two weeks with Brno, Moravian wine country, Olomouc and a mountain day in the Krkonose sits comfortably in 10 GB. Remote workers staying a month should budget around 20 GB, especially if you're working from cafes rather than one co-working space with reliable Wi-Fi.
Yes, tethering and hotspot are supported, so you can share your connection with a laptop or a travel companion's phone. That's handy if you're working from Prague cafes or planning routes on a bigger screen. Your shared data comes out of the same plan allowance, so keep an eye on usage if several devices are connected at once or you're streaming, and pick a data size that gives you a bit of headroom.
These are data-only plans, so they don't come with a local Czech phone number for traditional calls or texts. In practice that's rarely a problem: you can call and message over the internet using apps like WhatsApp, FaceTime, Signal or Telegram on your data. Because an eSIM is a separate digital line, you can leave your physical home SIM in the phone to keep your usual number for any essential calls or bank verification texts.
For US, UK and other non-EU travellers, home carriers typically charge around 10 dollars a day for Czech roaming, and a Blikst multi-day plan runs well under a week of that. A local O2 prepaid SIM means a shop visit with your passport and a bit of Czech. EU travellers on roam like home already have Czech coverage included, so check your domestic plan first before buying anything extra.
