The cleanest move is to load a Czechia eSIM before you reach Vaclav Havel Airport. You walk off the plane already connected, skip the Relay shop queue, and dodge the airport markup that pushes a Vodafone visitor SIM to around 800 CZK for 10 GB. Prague Airport does sell physical SIMs at Relay convenience stores in both the duty-free zone and the arrivals hall, plus a 24-hour Vodafone vending machine in Terminal 2, and the whole airport has free WiFi. But those still mean stopping, paying tourist prices, and fitting a card while jet-lagged, and notably the cheap visitor pack will not even roam once you leave Czechia.

SIM and eSIM Options at Prague Airport
Vaclav Havel Airport Prague has two passenger terminals: Terminal 2 handles Schengen flights and Terminal 1 handles non-Schengen, including flights to and from the UK and the US. Connectivity options sit in both, mostly run through the Relay convenience-store chain rather than dedicated carrier counters. Here is where to look once you are through.
Quick Terminal Summary
Both terminals: Relay convenience stores that stock physical prepaid SIMs, open 24 hours, cash or card. There are Relay outlets in the duty-free area before passport control and in the arrivals baggage hall. Terminal 2 landside: a 24-hour Vodafone vending machine that dispenses SIMs. There is no full-service carrier SIM counter, and importantly no physical eSIM sold on a rack, so an eSIM is something you load on your phone, not buy at a till.
Relay Convenience Stores
Relay is the main place to buy a tourist SIM at Prague Airport. You will find a store in the duty-free area and another in the arrivals hall, on the left just around the corner after the sliding doors. They sell physical prepaid SIMs only, no tourist eSIMs, and they run 24 hours, which makes them the realistic option for a late or early arrival when nothing else is staffed. The trade-off is a thin menu of packs and airport pricing.
Vodafone Vending Machine
In Terminal 2 on the landside, a self-service Vodafone machine dispenses SIMs around the clock. It is handy as a 24-hour fallback, but you configure the SIM yourself with no staff to help if your phone does not cooperate, and the visitor data pack it sells is locked to Czechia with no EU roaming.
eSIM at the Airport
No one sells a tourist eSIM from a counter at PRG. What you can do is buy and install one online over the free airport WiFi the second you land, which is the exact same thing you could have done at home with a calmer head. That is why loading the profile before departure is the tidiest route of all.
Free Airport WiFi at Prague (Prague Airport WiFi Free)
Vaclav Havel Airport offers free WiFi across all terminals, which matters because it is what lets you activate an eSIM or buy a plan online the moment you arrive.
Open your WiFi settings
On your phone's WiFi screen, choose the network named Prague Airport WiFi Free (you may also see prg.aero-free). No password is needed to join.
Accept the terms
A sign-in page opens. Agree to the terms and confirm, and the connection goes live. When the WiFi icon shows you are connected, you are online and ready to activate an eSIM.
Use it across the terminals
The free WiFi reaches the gates, the arrivals hall, and the public areas of both Terminal 1 and Terminal 2, so you have a window to get connected before you head for the bus stop.
Treat the airport WiFi as a starting gun, not a connection
Useful as it is inside the building, the free WiFi does not follow you out. Step onto trolleybus 59 or into a taxi and it vanishes, right when you need maps for the ride into Prague. Public WiFi is also slower and less secure than your own mobile data. Use Prague Airport WiFi Free to confirm your eSIM has connected, then rely on the eSIM for the trip itself.
Prague Airport to the City: Transit and Data En Route
Vaclav Havel Airport sits about 17 km northwest of the center, and there is no train or metro station at the airport itself, so the standard route is a short bus to the metro. This is exactly the stretch where you want live data to navigate the transfer. Here are the main options.
| Option | Route | Time | Fare (one way) |
|---|---|---|---|
| Trolleybus 59 + Metro A | T1/T2 to Nadrazi Veleslavin, then green line to the center | 17 min bus, then 10 to 12 min metro | One 90-min ticket, 40 to 50 CZK |
| Airport Express (AE) bus | Direct to Hlavni nadrazi (main train station) | About 40 to 45 min | 100 CZK (AE-only ticket) |
| Taxi or ride-hail | Door to door to central Prague | 25 to 40 min, traffic dependent | Roughly 500 to 700 CZK |
The local-transit route is the value pick: trolleybus 59 (which replaced the old bus 119 in 2024) leaves from outside both terminals every 4 to 5 minutes and reaches Nadrazi Veleslavin in about 17 minutes, where you change to metro line A for a 10 to 12 minute ride to Mustek and the old town. A single 90-minute PID ticket of 40 to 50 CZK covers the whole journey, bus and metro together. The Airport Express goes straight to the main train station for 100 CZK, but that AE ticket only works on the AE bus, not on regular Prague transport.
Data coverage on the ride in
Your own eSIM is the most reliable connection for the trip into town. Trolleybus 59 runs at street level on full network coverage, and the moment you transfer to metro line A you stay connected too, because every Prague metro station and tunnel carries signal. That continuity means your maps, ticket app, and messages keep working the entire way from the terminal to your hotel, without depending on patchy onboard or station WiFi.
Why Load an eSIM Before You Arrive
There is a strong case for sorting your connection before you even leave home, and it comes down to time, price, and the EU roaming catch unique to Czech visitor SIMs.
Pre-loaded eSIM
Buying at the airport
The simple way to do it
Buy a Czechia or Europe eSIM a day or two before you fly and add the profile while you still have home internet. Keep the line off until you reach Prague, then enable it in your settings and you are connected straight away, no Prague Airport WiFi Free login required. If you are unsure which plan fits, our Czechia eSIM guide lays out the networks and data sizes.
Prague Airport SIM Prices vs an eSIM
The convenience of buying on arrival has a price, and at Prague Airport it comes with an extra string attached. Typical 2026 airport pricing looks like this:
| Where | Typical plan | Price |
|---|---|---|
| Relay / Vodafone machine | Visitor data SIM, ~10 GB (no EU roaming) | About 800 CZK (~$35) |
| City Vodafone store | Prepaid bundle, ~15 GB | About 430 to 500 CZK (~$19-22) |
| Online eSIM (Czechia) | Short stay, capped data | From about $5 |
| Online eSIM (Europe) | Multi-country, larger data bucket | Around $20 to $30 |
| Online eSIM (unlimited) | Holafly, unlimited data | From about $7 per day band |
The pattern is clear: the airport visitor SIM at roughly 800 CZK is both the priciest way to get 10 GB and the only one that stops working at the border. A city-store prepaid is far better value, and an online eSIM beats both on convenience, starting near $5 for a short Czechia plan and around $20 to $30 for a Europe-wide plan that follows you into Germany, Austria, or Poland. The airport SIM mainly earns its keep if you specifically want a Czech phone number in hand.
The verdict
Load a Czechia or Europe eSIM before you fly and use Prague Airport WiFi Free only to confirm it has connected. Keep the Relay shops in mind purely as a backup if your phone turns out not to support eSIM, or if a Czech number is something you genuinely need. To match a plan to your trip length, run the eSIM Finder.
Frequently Asked Questions
Where can I buy a SIM card at Vaclav Havel Airport Prague?
At Relay convenience stores, which sit in the duty-free area and in the arrivals baggage hall, plus a 24-hour Vodafone vending machine in Terminal 2 landside. Relay sells physical prepaid SIMs only, no tourist eSIMs, and the shops are open around the clock, taking cash or card. There is no full-service carrier counter, and the cheapest visitor pack does not roam beyond Czechia, so weigh that against an eSIM.
What is the free WiFi network name at Prague Airport?
Connect to Prague Airport WiFi Free (you may also see it listed as prg.aero-free). It needs no password: join the network, accept the terms on the sign-in page, and you are online. The free WiFi reaches the gates, arrivals, and public areas of both Terminal 1 and Terminal 2, and it is the easiest way to activate an eSIM the moment you land before heading for the bus into the city.
How do I get from Prague Airport to the city, and will I have data on the way?
The cheapest route is trolleybus 59 from outside the terminals to Nadrazi Veleslavin, about 17 minutes, then metro line A for 10 to 12 minutes into the center, all covered by one 90-minute PID ticket of 40 to 50 CZK. You stay connected the whole way: the bus runs on full street-level coverage and the metro has signal in every station and tunnel, so your own eSIM keeps maps and the ticket app live throughout.
Is the airport SIM at Prague more expensive than an eSIM?
Yes, usually. The Vodafone visitor data SIM at the airport runs about 800 CZK for 10 GB and carries no EU roaming, while a city-store prepaid of about 15 GB is closer to 430 to 500 CZK. Online eSIMs start near $5 for a short Czechia plan and around $20 to $30 for a Europe-wide plan, so for the same data an eSIM typically costs less, skips the queue, and keeps working across borders.
Is it better to set up my eSIM before or after I land in Prague?
Set up the eSIM profile before you fly while you still have home internet, then leave the line off until you reach Prague and switch it on in your settings to get data straight away, with no shop visit and no airport WiFi login needed. Activating after landing works too, but only once you connect to Prague Airport WiFi Free first, which means a few extra minutes standing in arrivals before you are online.
