Czech Republic travel data eSIM
What is a Czech Republic eSIM?
Traveling to the Czech Republic? A data‑only eSIM lets you explore Prague’s historic streets, Brno’s vibrant cafés, and the fairy‑tale charm of Cesky Krumlov without hunting for a local SIM. Install it before you leave, keep your home number, and stay online as soon as you arrive on Czech soil.
In the Czech Republic the eSIM connects to O2 5G and Vodafone 5G networks. Your chosen data allowance runs from the moment you first access the internet there, letting you browse maps, check train times, or order food while you wander the country.

Questions people actually ask
If yours is not here, write to us — we answer within 24 hours.
Which operators does the Czech Republic eSIM use and what does that mean for a traveller?
The eSIM works with O2 5G and Vodafone 5G. That gives you access to the services those carriers provide, so you can use data for navigation, bookings, and everyday online tasks while in the country.
Does the eSIM also work in a neighbouring country of the Czech Republic?
No, this is a single‑country plan valid only in the Czech Republic. Regional plans are available if you need connectivity in neighboring nations such as Austria or Poland.
Which plan size suits a trip to Prague and Cesky Krumlov?
As a rough guide, a 5 GB or 10 GB 30‑day plan often covers two city visits, allowing enough data for maps, transport apps, and occasional streaming.
Will I lose my own phone number?
No. Your physical SIM stays in the phone and keeps your number for calls and WhatsApp. The eSIM only carries data, so both work side by side.
When does my plan start counting down?
When the eSIM first connects to a network at your destination — not when you buy it. So you can install it days before you fly without losing any time.
Is my phone compatible?
Most phones from 2018 onwards are: iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later. Your phone also has to be carrier-unlocked. Dial *#06# — if an EID appears, you have eSIM. Full list on our Device Compatibility page.
How fast will I get my QR code?
Usually within a couple of minutes of payment, by email. If it has not arrived, check spam first, then write to us and we will resend it immediately.
Can I use hotspot or tethering?
Yes, on every plan we sell. Share the connection with a laptop, a tablet or the rest of your group.
What if I change my mind?
If you have not installed the eSIM, you get a full refund within 180 days. Once a profile is activated and data has been used it cannot be refunded — the allowance is consumed from the network. Full detail in our Refund Policy.
Do you sell plans for groups?
Yes. For Umrah and Hajj groups, student trips and tour operators we deliver the QR codes as a single batch before departure, at group rates. Email us with your group size and destination.
