688 of these 1542 plans were checked against the seller's own shop on 17 October 2026. The rest come from the seller's own feed or plan pages and are not yet independently checked.
The Watchdog Pick is chosen automatically: the lowest real price per GB of the 1542 plans in this view. Bulk data pools above 50 GB cannot win it, because their per GB rate only exists if you use data no traveller uses. Providers cannot pay for it, and a commission never changes the ranking. Prices are shown in USD and can change at checkout.
Price per GB counts only data you can use inside the validity, at most 3 GB a day, so a big pool on a short validity cannot buy the top spot. Every provider's best two plans come first, then the rest. A plan marked Unverified price undercuts every other provider here by more than half and waits at the end until we have checked it on the seller's site. How we rank
Unlimited rows show the daily amount at full speed. Some rows also show the speed after that amount. A row with no speed does not mean the plan stays fast, so check the plan on the seller's site.
Some links here earn us a commission. It never changes the order. How we make money The row marked Sponsored is a paid placement shown above the ranking, not part of it. Advertise here.

Cheapest eSIM for Czech Republic: the numbers
As of 17 October 2026, 06:01 GMT, the cheapest eSIM for Czech Republic is Horizon eSIM with 1 GB for 7 Days at $0.28. That is $0.28 per GB, the best rate of the 1542 plans we compare from 57 providers. 1020 plans include 5G. 593 support top ups. That timestamp is the exact moment of our latest price check, and the table above always shows the live order.
Which is the best eSIM for Czech Republic?
There is no single best eSIM for Czech Republic, because the right plan depends on how long you stay and how much data you use. What we can do is rank the 1542 plans on the numbers, as they stand on 17 October 2026:
- Best value overall Horizon eSIM, 1 GB for 7 Days at $0.28. That is $0.28 per GB, the lowest real rate of every Czech Republic plan we track.
- Best for a long stay Yatelo, 20 GB for 30 Days at $6.99, $0.35 per GB. The best rate among plans that last 30 days or more.
- Highest daily cap on an unlimited plan ByteSIM, 30 Days at $78.90, full speed up to 10 GB a day. Set that daily cap against the fixed plan above before you pay for the word unlimited.
None of these picks is chosen by a person. Each one is the first row of a sort on live prices, so it changes whenever a provider moves a price, and Horizon eSIM did not pay to be named here.
Which mobile networks does Czech Republic have?
All three networks passed 90 percent 5G population coverage by early 2025, with Vodafone at 96.47 percent, O2 at 93.56 percent and T-Mobile at 93.40 percent as of November 2024. 4G is effectively everywhere people live.
- T-Mobile: T-Mobile is the most awarded Czech network, taking 12 of 14 awards outright or jointly in Opensignal's February 2025 report, with 5G reaching over 93 percent of the population.
- O2: O2 finished its network modernisation with about 5,300 5G base stations covering 96 percent of the population and won Opensignal's 5G Coverage Experience award outright.
- Vodafone: Vodafone reported the highest 5G population coverage of the three at over 96 percent in late 2024 and is a joint Opensignal winner for availability and reliability.
The Czech Republic has an active MVNO market riding on the three host networks, but travel eSIMs and tourist SIMs all end up on O2, T-Mobile or Vodafone infrastructure anyway.
The eSIM plans we compare on this page connect to:
The list above is Czech Republic's operator market. The badges are the networks our tracked plans actually roam onto, which can be a subset of it, and the same network is sometimes sold to roaming partners under a different brand name. So a guide praising an operator you do not see badged here is describing a local SIM, not the travel eSIMs compared above.
Is 5G available in Czech Republic?
5G is close to nationwide on all three carriers, and the operators signed a five year deal with the government to extend 5G into 600 underserved rural areas, so coverage keeps improving outside the cities.
How much data do you need in Czech Republic?
Light use is about 500 MB a day. That covers maps, messages, and some browsing. Normal use with photos, social apps, and short videos runs 1 to 1.5 GB a day. Streaming and hotspot use can eat 2 to 3 GB a day. Here is what each size costs in Czech Republic right now:
Are unlimited eSIMs for Czech Republic really unlimited?
Not always. 717 of the 1542 plans above are sold as unlimited, and most of them carry a daily fair use cap. A further 36 plans are unlimited in a different way: one capped speed for the whole plan, shown next to the word Unlimited in the table. For Czech Republic the caps we can see published are 0.3 to 10 GB a day: past that the speed drops, often to 1 Mbps or less, until the clock resets. That is fine for messages and maps, slow for video. At $0.28 per GB from Horizon eSIM, a fixed plan often works out cheaper than unlimited unless you genuinely burn several GB a day. That is why we rank by price per GB and not by the word on the label.
Here is what each seller on this page actually allows per day before it slows you down. No seller publishes this next to its rivals, which is exactly why it is worth showing.
Every seller that publishes a daily allowance is listed on our daily data caps page, with the cheapest plan at each one. The gap between the top and bottom of that table is the whole point. Two plans both sold as unlimited can differ several times over in what you actually get at full speed, and the cheaper one is not always the smaller allowance.
eSIM or a local SIM card at the airport in Czech Republic?
An eSIM is ready before you land. No queue, no shop, no handing over your passport at a counter for a tourist SIM card. Data for Czech Republic starts at $0.20 on this page, which is hard for airport kiosks to beat. A local SIM still makes sense if you need a local phone number or plan to stay for months. For a normal trip, the eSIM wins on price and effort.
Setting up your Czech Republic eSIM
Pick the plan, not the brandThe cheapest rate in Czech Republic today is $0.28 per GB from Horizon eSIM, against a median of $1.25. The QR code arrives by email within minutes of paying.
Install before you flyScan the QR code on wifi at home. Installation needs a connection, and the one thing you will not have when you land in Czech Republic is a working connection.
Turn it on when you landEnable the eSIM and turn on data roaming for it, then give it a minute to attach to O2, T-Mobile, Vodafone. Expect 5G where the network reaches, 4G everywhere else.
Know what happens when it runs out593 of the 1542 plans here can be topped up, so running out is not the end of the trip. If you would rather over buy than top up, the cheapest plan with at least 5 GB is ASIMGO at $2.39.
Good to know before you land in Czech Republic
Bring a passport when buying a local SIM. EU roam like at home applies, so anyone with an EU SIM can simply roam at domestic rates.
At Prague airport there is a Vodafone shop in Terminal 2 arrivals open 6am to 10pm, with tourist plans from about 800 CZK for 10GB over 30 days. City centre shops from all three operators are 10 to 20 percent cheaper, so many travellers wait.
Coverage is a non issue on the main tourist trail. If you are on an EU plan you likely do not need a local SIM at all for a short trip.
Czech Republic Travel eSIM FAQ
Everything you need to know about using an eSIM in Czech Republic
What is the cheapest eSIM for Czech Republic?
Right now the cheapest option ranked by price per GB is Horizon eSIM with 1 GB for 7 Days at $0.28. That works out to $0.28 per GB. Prices change often, so the table above is re-sorted at every price check.
Which is the best eSIM for Czech Republic?
It depends on the trip, so we rank rather than pick a favourite. On today's prices the best value for Czech Republic is Horizon eSIM at $0.28 per GB, the lowest real rate of the 1542 plans we compare. For heavy daily use there are 717 unlimited plans, most with a daily fair use cap, and they only win if you genuinely burn several GB a day. Every pick on this page is the first row of a sort on live prices. No provider can pay to be named best.
Is eSIM available in Czech Republic?
Yes. We track 1542 prepaid travel eSIM plans from 57 providers that work in Czech Republic, roaming onto O2, T-Mobile, Vodafone. You need a phone that supports eSIM and is not locked to a carrier; most iPhones from the XS onward and most flagship Android phones from 2019 on qualify.
Which networks will my eSIM connect to in Czech Republic?
The plans we compare connect to O2, T-Mobile, Vodafone. The exact network depends on the plan you pick. Check the plan details before you buy if one network matters to you.
Do Czech Republic eSIMs support 5G?
1020 of the 1542 plans we track for Czech Republic include 5G where the local network offers it. The rest run on 4G, which is still fine for maps, calls over apps, and video.
Can I buy a Czech Republic eSIM online before I travel?
Yes, and you should. Every plan on this page is sold online and delivered by email as a QR code within minutes. Install it on wifi at home, leave the line switched off, and turn on data roaming for it when you land in Czech Republic. The validity clock on most plans only starts when the eSIM first connects.
Can I top up my Czech Republic eSIM if I run out?
Yes. 593 of the 1542 plans here support top ups, so you can add data without buying a new eSIM. The rest need a fresh plan once the data ends.
Is an eSIM cheaper than a local SIM card in Czech Republic?
For a trip of days or weeks, usually yes. Data for Czech Republic starts at $0.20 for 100 MB on this page, with no queue, no shop and no passport handed over at a counter. A local SIM card can still win if you stay for months or need a local phone number.
Will I still receive bank SMS and OTP codes?
Yes, if you keep your home SIM active. Travel eSIMs are data only. Your phone can hold both at once, so leave your normal SIM on for SMS and use the eSIM for data. Turn off roaming data on the home SIM to avoid charges.
Do these eSIMs include a phone number or calls?
The plans we compare are data only, so there is no local number. Calls work fine over WhatsApp, FaceTime, or any app that uses data. If you need a real local number, a local SIM is the better tool.
Does a Czech Republic eSIM work on iPhone and Android?
Yes, on any carrier unlocked phone with eSIM support: iPhone XS or newer, Google Pixel 3 or newer, Samsung Galaxy S20 or newer and most recent flagships. The plans are identical on both; only the install steps differ, and both take about a minute on wifi.
How many GB do I need for a week in Czech Republic?
Around 3 to 5 GB covers a week of maps, messaging, and normal browsing. Heavy video or hotspot use needs 1 to 2 GB per day. Today the cheapest plan with at least 5 GB is ASIMGO at $2.39.
Which Czech Republic eSIM gives the most data per day?
Of the plans sold as unlimited here, ByteSIM allows the most at full speed, 10 GB a day from $4.90. The smallest allowance on this page is 300 MB a day, from 4 sellers. Every one of them is advertised as unlimited, and past the daily allowance the speed drops, often to 1 Mbps or less, until the next day. Check the allowance, not the word.
