Traveller's guide

Staying connected in Czech Republic — what to know

Coverage is excellent in Prague and holds up well on day trips to Cesky Krumlov, Karlovy Vary and Kutná Hora.

Bolt and Uber both run in Prague and Brno and are cheaper than street taxis, which are notorious for overcharging tourists.

As an EU country, your eSIM keeps working across the border in Germany, Austria and Poland.

FAQ

Questions, answered

Will the Czech Republic eSIM work on my phone?+
Yes, as long as your phone supports eSIM and is carrier-unlocked. That covers iPhone XS and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer, and most modern Android phones. Dial *#06# to check for an EID number.
How fast is the data in Czech Republic?+
Your eSIM connects to the strongest available local networks at 4G/5G speeds — fast enough for maps, video calls, streaming, social media and mobile hotspot.
Do I need a passport or registration?+
No. There's no ID check, no paperwork and no SIM registration. You buy online, receive a QR code by email, and install it yourself in under two minutes.
When does my plan start?+
Validity begins the moment your eSIM first connects to a network in Czech Republic — not at purchase. You can install it days ahead of your trip with zero waste.
Can I top up if I run out of data?+
Yes. Add more data to the same eSIM in seconds from your account — no new QR code and no reinstall needed.
Can I keep my normal number for calls and texts?+
Yes. The eSIM runs alongside your physical SIM, so your home number stays active for calls and bank codes while the eSIM handles data in Czech Republic.
What happens when my data runs out?+
Your connection simply pauses — no surprise bills, ever. Just top up to keep going, or buy a fresh package.
Can I use it as a mobile hotspot?+
Yes, tethering and hotspot are included, so you can share your connection with a laptop or a travel companion's phone.
Need unlimited data?
Skip the data cap — our Unlimited plan gives endless data for a fixed daily price.
