No pocket Wi-Fi or SIM counter to find when you land in Czech Republic, and nothing to return before you fly home. The eSIM is installed before you leave.
Share with your laptop
Hotspot is allowed on the plan selected above, so a second device can use the same data in a cafe or a hotel room.

Czech Republic travel data guide
A Czech Republic eSIM from RoamZivo is a prepaid data plan for Czech Republic that you install before you fly. Plans in Czech Republic run on O2 and Vodafone, with 5G where the operator offers it. The eSIM is data only, so your own SIM stays in for calls and texts.
There are 19 plans to choose from. Data sizes run from 1 GB to 10 GB, validity from 1 to 30 days, and prices start at $1.99. Unlimited plans are listed too, each with its own fair use line. Hotspot sharing is supported on every plan. Top ups are available on some of the fixed data plans and go onto the same eSIM.
Visiting more than one country? The Europe eSIM covers Czech Republic and 33 other countries on one plan, from $1.99. The Global eSIM covers Czech Republic and 126 other countries on one plan, from $18.99.
Your days start the first time the eSIM connects in Czech Republic, not when you buy, so you can install it at home days early. For a week of maps, messaging and social apps, most travellers are fine with 3 to 5 GB. Video calls or streaming need more, or an unlimited plan. Travel data in Czech Republic from RoamZivo arrives as a QR code by email, with a copy kept in your account.
Czech Republic FAQ
Does the eSIM work everywhere in Czech Republic?
It connects wherever O2 and Vodafone have signal, which is the same network local customers use. The eSIM is data only.
When do my days start?
On the first connection in Czech Republic, not at purchase. The plan selected above (2 GB) runs for 15 days from that moment. You can install the eSIM at home and the clock stays still until you connect.
Do I get a local phone number in Czech Republic?
No. The eSIM is data only. Your own SIM stays in for calls and texts, and WhatsApp keeps working over the eSIM data.
Can I share data with my laptop?
Yes. Hotspot sharing is supported on the plan selected above, so your laptop or tablet can use the eSIM data through your phone.
Is the Czech Republic eSIM 4G or 5G?
The Czech Republic plans are labelled 3G/4G/5G or 4G/5G, and both operators, O2 and Vodafone, are listed as 5G in our catalogue. You need a 5G phone to use it. Without one, the same plan works on 4G.
Is 5 GB enough for a month in the Czech Republic?
5 GB over 30 days is enough for a month in the Czech Republic if you have WiFi where you sleep and use mobile data for maps, transport apps and messaging. If you watch video on the move or work from cafes on a hotspot, take 10 GB or a 30 day unlimited plan.
Can I make calls with the Czech Republic eSIM?
Not regular phone calls, because the Czech Republic eSIM is data only and has no number. You can call through any app that uses the internet. Your home SIM stays active for normal calls and SMS, at whatever rate your carrier charges abroad.
How soon do I receive the eSIM after paying?
The QR code for your Czech Republic eSIM is sent by email after payment goes through, and a copy is stored in your customer account. If you can't see the email, look in the spam folder and then check the account before writing to support.
Can I buy the plan weeks before my Czech trip?
Yes, you can buy and install a Czech Republic plan well ahead. The days are counted from the first time the eSIM connects to a network in the country, so nothing is used up while the eSIM waits on your phone at home.
Does hotspot use count toward my daily limit?
Yes, on Czech Republic unlimited plans, hotspot use counts toward the 1 GB or 3 GB of full speed data for that day. On fixed plans it is taken from the total allowance. Every plan allows hotspot, so the only limit is the data itself.
Will the Czech plan keep working if I cross into another country?
No, a Czech Republic plan provides data inside the Czech Republic only. For trips that cross a border, the Europe regional plan also includes the Czech Republic. Check the list of countries on that plan's page against your route before buying.
How do I top up if I run low?
The plan selected above does not offer top ups. Buy a new plan from this page instead and install it as a second eSIM.
