Most people give Czechia a long weekend in Prague, or two weeks with Cesky Krumlov, Kutna Hora and Brno added. For 15 days of unlimited, Airalo asks $48, Saily $48.99 and Holafly $50.50. Ubigi gives 30 GB at full speed for 15 days at $36. For a month, $69 to $73.90, and Ubigi and Nomad sell no 30-day unlimited here at all. Ringo Light charges $12.99 for 2 weeks and $21.99 for 30 days, one payment each, nothing renews.
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 has no speed cap: the 2 weeks starts with 10 GB and the 30 days with 20 GB, and when you have used 80% we add 10 GB once and charge the $12.99 top-up. A heavy two weeks with us costs $25.98, under Ubigi's $36 for 15 days. A heavy month costs $34.98, just under Ubigi's 50 GB bucket at $36 and half of Airalo's month.
For a short trip, Ringo Light sells no 3-day or 7-day plan. Nomad sells 3 days of unlimited at $11 and a week at $25. Our 2 weeks at $12.99 still costs less than any rival's week.
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. None of the six names 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 a Europe plan is the better buy.
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. Its listing is from June; we could not read saily.com on the day.
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. Our 2 weeks starts with 10 GB for $12.99 and our 30 days with 20 GB for $21.99. For 10 GB that lasts a month, Ubigi at $14 is the better buy, and Nomad sells 20 GB for 30 days at $20, $1.99 under our 30 days. We would rather you read that here than at checkout.
Ringo Light is our own data eSIM, sold to fund the full Ringo, one plan that works everywhere with your own number ported onto it. For Czechia it sells two trips, both unlimited data at full speed with no speed cap: 2 weeks at $12.99, starting with 10 GB, and 30 days at $21.99, starting with 20 GB. Each adds 10 GB once at 80%, charged at $12.99. One payment, nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app.
The card to buy it is just below this article.
A long weekend in Prague. Nomad unlimited, 3 days, $11. Ringo Light sells no 3 days; its 2 weeks is $12.99 if the trip might run longer.
A week or two from Prague to Cesky Krumlov and Brno. Ringo Light unlimited, 2 weeks, $12.99, less than any rival charges for one week.
Two weeks, light use, budget first. Ubigi 10 GB for 30 days at $14.
A month in Prague, working from cafés. Ringo Light unlimited, 30 days, $21.99, starting with 20 GB and adding 10 GB once for $12.99. Nomad 20 GB for $20 if you know you will stay under 20 GB.
You need your own number to keep ringing. None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.
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.
Charles Bridge, Prague. A fourteenth century stone bridge over the Vltava, lined with thirty statues, with Prague Castle on the hill behind it. Cross it at sunrise, before the crowds and the stalls arrive. Bolt and Uber both run in Prague, handy for the airport and late nights.
Old Town Square and the astronomical clock, Prague. The square between the twin spires of the Tyn Church and the Old Town Hall, whose medieval astronomical clock puts on its show of apostles every hour. Climb the town hall tower for the view in the photo. Buy tram and metro tickets in the PID Litacka app and start the ticket before you board.
Cesky Krumlov, South Bohemia. A castle with a painted tower above a tight bend of the Vltava and a medieval town inside it, a UNESCO site. About three hours from Prague by bus; stay a night to see it after the day trips leave. Buses from Prague sell out on summer weekends. Book a seat in the carrier's app a few days ahead.
St. Barbara's Church, Kutna Hora. A Gothic church built by the town's silver miners, with three tent roofs and a forest of flying buttresses. The bone chapel of the Sedlec Ossuary is on the other side of town; Kutna Hora is about an hour from Prague by train. A combined ticket covers the ossuary and the church. Buy it online and keep the QR code on your phone.
The colonnades of Karlovy Vary, West Bohemia. A spa town of pastel hotels along a narrow valley, where hot springs run from taps under open colonnades. People walk from spring to spring sipping from spout cups; the water is warm and mineral. A map of the springs on your phone shows which colonnade holds which one and how hot it runs.
Pravcicka brana, Bohemian Switzerland National Park. The largest natural sandstone arch in Europe, reached on a forest trail from Hrensko. Walking on the arch has been banned since 1982; the view is from the terrace of the small chateau built beside it. Signal drops in the gorges near the German border. Download the offline map and trail before you set out.
Petrov Hill and the cathedral, Brno. The twin spires of the Cathedral of St. Peter and Paul rise over Czechia's second city, seen here from Spilberk Castle. Its bells ring noon at eleven o'clock, a custom said to date from the Swedish siege of 1645. Brno is about two and a half hours from Prague by train. A rail app shows the platform and any delay.
Lednice Castle, South Moravia. A neo-Gothic chateau in a huge landscape park with a minaret and a lake, part of the Lednice and Valtice UNESCO area. The wine villages around it hold harvest festivals in September. Lednice sits close to the Austrian border. A Czechia plan stops at the border, so buy a Europe plan if you carry on to Vienna.
We priced Airalo, Holafly, Saily, Nomad, Ubigi and Ringo Light for Czechia on 28 September 2026, all on the same day, in US dollars. Each rival's price comes from its own website where it showed dollars, otherwise from an esimdb.com listing, and every source and its date is listed below. Ringo Light's prices come from the catalogue our checkout charges.
We compare the trips people actually book: a week, two weeks and a month of unlimited data, and a 10 GB bucket. We read each brand's fair use and speed rules and quote them as the brands state them. We did not run speed tests, so this page makes no speed claims for any brand.
Ringo Light is our own product. We put it in the table on the same terms as everyone else, and where a rival is the better buy the page says so.
Left out: Maya Mobile, we could not read its own prices for this country on the day, so it stays out rather than being guessed.

For two weeks or a month of unlimited data, Ringo Light: $12.99 for 2 weeks and $21.99 for 30 days on 28 September 2026, against $48 for 15 days and $69 for 30 days at Airalo. For 3 days, Nomad at $11. For 10 GB over 30 days, Ubigi at $14; for 20 GB, Nomad at $20.
Airalo, Holafly and Nomad ride O2 and Vodafone, and Ubigi O2. Saily does not name its network on its listing. Both networks cover Prague, Brno and the main routes well; signal thins in the border mountains and national parks.
Every brand has a limit somewhere. Airalo slows you after 3 GB a day, Saily after 5 GB, Nomad after 2 GB, Ubigi after its fixed full-speed amount. Holafly states no daily cap for your own phone. Ringo Light has no speed cap: it starts with 10 or 20 GB and adds 10 GB once at 80%, charged.
Czechia has been in the EU since 2004, so a home plan from an EU country usually roams there at home prices, within a fair use limit. Travellers from the US, the UK, Canada or Australia usually pay a daily roaming fee, and that is where a travel eSIM saves money.
