Your Czechia eSIM in two questions
Which Czechia eSIM plan is right for your trip?
From a Prague weekend to a long stay in Plzeň, here is which plan to pick.
- A three-day city break in Prague: pick 2 GB for 15 days for standard use, so maps, messages and a few rides are all sorted.
- A fortnight touring Brno, Český Krumlov and Karlovy Vary: choose 10 GB for 30 days for standard use, which gives you room for maps, social media and some video.
- A long stay in Plzeň: pick 20 GB for 30 days for standard use, which suits music, social media and everyday messages.
- A trip that also takes in other European countries: the Europe bundle covering 31 countries is built for routes like that.
Most plans can be topped up, and the longest is 50 GB for 180 days.

These eSIMs cover the Czechia and more countries on one plan.
Will my eSIM have signal in the Czechia?
O2 and Vodafone are the networks your eSIM joins in the Czechia, and it can connect on 5G. Cities, towns and main roads are well covered, but signal can be patchy in remote mountain valleys, so save your offline maps before a trip into the hills. Your phone picks between O2 and Vodafone by itself, so there's nothing to set up.
Your data reaches the internet through France, the Netherlands or the United Kingdom, which is a normal setup for travel eSIMs. Learn more on the IP address help page. If you choose a daily plan, your data slows to 512 Kbps once you've used that day's allowance.
How much data do you need in the Czechia?
Light: maps, messages, email (about 0.25 GB a day). Standard: plus social, music, some video (about 0.7 GB a day). Heavy: plus streaming, video calls, hotspot (about 1.8 GB a day).

Using your phone in the Czechia: data tips
- Landing: Land at Václav Havel Prague (PRG), switch your eSIM on, then turn on data roaming for the eSIM line. Install it at home on Wi-Fi first, so you are ready at the gate.
- Getting around: From Prague to Brno, Český Krumlov, Karlovy Vary or Plzeň, Uber and Bolt are the ride apps to load before you land, so a lift is one tap away.
- Staying in touch: WhatsApp and Messenger carry your messages over data, and your home number stays on for calls and texts. Set up WhatsApp on your home number before you fly so nothing gets missed.
- Data to buy: Light use, like maps, messages and email, is about 0.25 GB a day. Standard use with social media, music and some video is about 0.7 GB a day, and heavy use with streaming and hotspot is about 1.8 GB a day. Most plans can be topped up if your trip runs long.
Czechia eSIM questions
How much is an eSIM for the Czechia?
Czechia eSIMs start at £3.99 for 1 GB over 7 days. A 5 GB plan for 30 days costs £5.99. Prices include any taxes and show in pounds, euros or dollars.
Which networks does the Czechia eSIM use?
Your eSIM connects to O2 and Vodafone in the Czechia, with 5G where the network has it. Your phone picks the strongest signal automatically.
When does my Czechia eSIM start?
Most plans start the moment your eSIM first connects to a network in the Czechia, so you can buy and install it at home before you fly. Install it within 180 days of buying.
Can I top up my Czechia eSIM?
Yes. Most Czechia plans can be topped up from your eSIM page in two taps, with no new QR code. The plan table on this page shows which ones.
Why does my IP address show another country?
Czechia plans route your data through France, a normal setup for travel eSIMs. Websites and apps may show that country's content; your speed and coverage in the Czechia are not affected.
Does it come with a phone number?
Every eSIMology plan is data only. Keep your own SIM switched on for calls and texts, and use WhatsApp, FaceTime or any calling app over your eSIM's data.
What if my plans change?
Cancel an eSIM you haven't installed within 30 days for a full refund to your card, in two taps from your eSIM page.
Does Bolt work with an eSIM at Prague airport?
Yes. Land at Václav Havel Prague (PRG), switch on your eSIM, and you can open Bolt or Uber to book a ride into town. Both apps need mobile data, so do this before you reach the taxi rank.
Can I use WhatsApp and Messenger in Czechia?
Yes. WhatsApp and Messenger both run on your eSIM's mobile data, so you can keep in touch from Prague, Brno, Plzeň or Karlovy Vary. Just check mobile data is switched on for your eSIM line, then open the app as usual.
How much data do I need for a week in Czechia?
A week of standard use in Czechia, with social media, music and some video, comes to about 4.9 GB. Light use of maps and messages is about 1.8 GB, and heavy use with streaming and hotspot is about 12.6 GB.
Is there 5G in Czechia?
Yes. Czechia has 5G, and your eSIM can use it on O2 and Vodafone where those networks offer it. Check that your phone supports 5G before you fly, as older handsets may use 4G instead.
Which eSIM covers Czechia and other European countries?
Czechia is included in our Europe eSIMs, so one bundle can cover a multi-country trip. If your trip crosses into other countries, a Europe option covering 31, 33 or 34 countries may suit you better.
What happens to my speed once a daily plan's allowance runs out?
Once a daily plan's allowance is used up, your eSIM drops to 512 Kbps, which is far too slow for streaming. Save video for when you're on Wi-Fi in your Prague hotel.
