The short answer
Six travel eSIMs sell a plan for Czechia, the Czech Republic, and get most of the traffic for this search. I priced all six on the same day, for a long weekend in Prague, two weeks out to Cesky Krumlov, Karlovy Vary and Brno, and a month, and I read the fine print on unlimited. Here is where I think each one wins.
Unlimited data at full speed for 2 weeks at $13.99 or 30 days at $26.99, nothing renews. Airalo asks $48 for 15 days and $69 for the month.
20 GB for 30 days at $20, and 3 days of unlimited at $11, 2 GB a day at full speed, on O2 and Vodafone.
10 GB for 30 days at $14 on O2 with 5G, installed by QR code, no app needed. 50 GB for 30 days at $36.
Days, not gigabytes, no daily cap stated for your own phone, on O2 and Vodafone. $27.50 for a week.
Prices read on 11 November 2026: Airalo, Holafly, Saily, Nomad, Ubigi on their own sites or listings, Ringo Light from its catalogue. All in US dollars unless stated. Treat every number as a snapshot.

The 30-day plan at each brand. Ringo Light is unlimited data at full speed. Ubigi and Nomad sell no 30-day unlimited for Czechia; Ubigi's 50 GB for 30 days is $36.
Holafly sells no buckets. Ringo Light sells no bucket either: its 2 weeks is unlimited and lasts 2 weeks, not 30 days.

Want to keep your own number abroad?
That is the full Ringo service: one plan that works everywhere, with your own number included.
It is a separate product from Ringo Light and it is still being built, so it is not on sale yet. Join the waitlist to hear when it opens.
What to do in Czechia, and what your phone needs for it
Eight places most first trips include, from Prague out to Bohemia's castle towns and spas and down to Moravia, with the one thing your data does for you at each. The cities and towns have good 4G and 5G; the sandstone gorges by the German border are where signal thins.
If you want unlimited for two weeks or a month: Ringo Light
Most people give Czechia a long weekend in Prague, or two weeks with Cesky Krumlov, Kutna Hora and Brno added, and that is the trip I priced. For 15 days of unlimited, Airalo asks $48, Saily $48.99 and Holafly $51.50. Ubigi gives 30 GB at full speed for 15 days at $36. For a month, $69 to $76.50, and Ubigi and Nomad sell no 30-day unlimited here at all. Ringo Light charges $13.99 for 2 weeks and $26.99 for 30 days, nothing renews.
I would read what unlimited means before you pick. Airalo gives 3 GB a day at full speed, then 1 Mbps. Saily gives 5 GB a day, Nomad 2 GB. Ubigi gives a fixed amount, then 2 Mbps. Holafly states no daily cap for your own phone and limits sharing to 1 GB a day. Ringo Light is unlimited data at full speed for the whole 2 weeks or 30 days.
For a long weekend, Ringo Light sells no 3-day plan. Nomad sells 3 days of unlimited at $11. For a week, the Ringo Light 7 days at $5.99 costs less than any rival's week, so I would take it over a week from anyone else.
Which network works best in Czechia
Czechia has three networks: O2, T-Mobile and Vodafone. All three cover Prague, the other cities and the main rail and road routes well, with 5G in the cities. Coverage thins in the border mountains and forests: Holafly names the Krkonose, Sumava and Bohemian Switzerland on its own page. Every travel eSIM here rides O2, Vodafone or both. I found none of the six naming T-Mobile.
Czechia is in the EU but keeps its own money, the koruna. Cards and phone wallets work almost everywhere in Prague and Brno; carry a little cash for small village shops and some pubs. A Czechia plan stops at the border, so for a trip that goes on to Vienna, Dresden or Krakow I would buy a Europe plan.
If you want a data bucket: Ubigi or Nomad
- Ubigi, $14 for 10 GB. The cheapest 10 GB for 30 days, on O2 with 5G, installed by QR code, no app needed. 25 GB is $26 and 50 GB $36.
- Saily, $14.99 for 10 GB. 20 GB at $23.99. Read from the esimdb listing on 29 October; saily.com refused the fetch.
- Airalo, $15 for 10 GB. Its Prosim plan on O2 and Vodafone, 20 GB for $24, buckets from $4 for 1 GB. The app is needed.
- Nomad, $16 for 10 GB. And the cheapest 20 GB at $20, on O2 and Vodafone.
- ✓Ringo Light, no buckets. The 2 weeks is unlimited for $13.99 and the 30 days unlimited for $26.99. For 10 GB that lasts a month, Ubigi at $14 is the better buy, and Nomad sells 20 GB for 30 days at $20, $6.99 under the Ringo Light 30 days. I would rather you read that here than at checkout.
What Ringo Light is
Ringo Light is the data eSIM Ringo sells to fund the full Ringo, and I write for Ringo. It is one plan that works everywhere with your own number ported onto it. For Czechia it sells three trips, all unlimited data at full speed with no speed cap: 7 days at $5.99, 2 weeks at $13.99 and 30 days at $26.99. Nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app.
The card to buy it is further up this page, just after the side-by-side table.
Pick by trip
Nomad unlimited, 3 days, $11. Ringo Light sells no 3 days; its 2 weeks is $13.99 if the trip might run longer.
Ringo Light unlimited, 7 days, $5.99, less than any rival charges for one week.
Ringo Light unlimited, 2 weeks, $13.99, a cent under Ubigi 10 GB for 30 days at $14.
Ringo Light unlimited, 30 days, $26.99. Nomad 20 GB for $20 if you know you will stay under 20 GB.
None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.
