1 · The short answer
Every travel eSIM sells Prague as part of a Czech plan or a Europe plan. We priced the six that get most of the traffic on the same day, for a long weekend, a week and two weeks with side trips, and looked at what your phone has to do between the airport, the metro and the old town.
2 weeks of unlimited data at $13.99, less than any rival here charges for 7 days. 30 days at $26.99. Nothing renews.
3 days of unlimited at $11, 2 GB a day at full speed. Ringo Light sells no 3-day plan.
10 GB for 30 days at $14, the cheapest bucket that lasts a month.
Days, not gigabytes, on Vodafone and O2, installed from a QR code. $27.50 for a week.
Prices read on 12 October 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.

2 · The prices, charted
US dollars, 12 October 2026. Airalo's bar is Prosim, its Czech plan. Ubigi's 15 days is 30 GB at full speed, then 2 Mbps. Nomad stops at 10 days.
The 30-day plan at each brand. Nomad and Ubigi list no 30-day unlimited plan for the Czech Republic.
Holafly sells no buckets. Ringo Light sells no bucket either: its 2 weeks is unlimited and lasts 2 weeks, not 30 days.

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.
4 · What to do in Prague, and what your phone does for you there
Seven places for a first visit, from the castle on the hill to the old town square. All are on foot or a short tram ride apart.
5 · Getting online at Vaclav Havel Airport
Prague Airport has 4G and 5G at every gate. Switch your eSIM on when you land. Bus 119 runs to Nadrazi Veleslavin on metro line A, and the Airport Express bus to the main station. Ride apps also pick up at the terminals.
Public transport tickets are sold in the PID Litacka app; buy one before you board and it is valid on buses, metro and trams.
6 · Metro, trams and the old town
Prague's metro has mobile coverage in its stations and tunnels, so your phone works underground. Trams cover the centre well, and tram 22 climbs to Prague Castle. The old town itself is best walked, with a maps app for the lanes that all look alike.
Prices in the old town vary a great deal. A maps app with reviews helps you find a pub a street away from the square at half the price.
7 · Day trips and the next country
Kutna Hora is an hour by train and Cesky Krumlov about three hours by bus; the Czech plan covers both. Vienna, Berlin and Budapest are each a few hours away. A Czech plan stops at the border; Ringo Light's Europe trip, 2 weeks at $22.99, covers the Czech Republic and its neighbours on one eSIM.
8 · Which plan fits a Prague trip
A long weekend: Nomad sells 3 days of unlimited at $11 and Airalo at $11.50. Ringo Light sells no 3-day plan, so for two or three nights one of those is the better buy.
A week: A week of unlimited costs $24 at Ubigi (20 GB, then 2 Mbps), $25 at Nomad, $26.50 at Airalo and $27.50 at Holafly. Ringo Light sells no 7-day plan, but its 2 weeks of unlimited data costs $13.99, less than any of those weeks. You simply have days left over.
Two weeks or a month: Ringo Light 2 weeks at $13.99 or 30 days at $26.99. Both cover all of the Czech Republic, Prague included, with nothing to change when you leave the city.
9 · What Ringo Light is
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 the Czech Republic, Prague included, it sells two trips, both unlimited data: 2 weeks at $13.99 and 30 days at $26.99. Nothing renews. Fair use policy, see Terms. The eSIM arrives by email and installs in one scan, no app.
Even against buckets, our 2 weeks at $13.99 costs less than 10 GB for 30 days at Ubigi ($14), Saily ($14.99), Airalo ($15) or Nomad ($16). The buckets last longer, 30 days against our 2 weeks. Ringo Light sells no buckets. The card to buy it is further up this page, just after the side-by-side table.

12 · How we compared, and our sources
We priced Airalo, Holafly, Saily, Nomad, Ubigi and Ringo Light for Prague on 12 October 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.
