English
An eSIM for the Czech Republic is a digital data plan for the phone you already own. There is no physical SIM card, no airport lines, and no passport needed. Your plan is ready on your SIMAREA account before you even leave home.
It works safely alongside your normal SIM. You keep your own number for calls and important text messages. Your data goes through the SIMAREA plan. Just turn off data roaming on your home SIM to avoid high bills.
Every plan here uses more than one partner network. Your phone joins one when you arrive and can switch to another if the signal weakens.
If you stay longer, top up your current plan with more data. You do not need to buy a new one.
What it is not: a local phone number. If you need a number for verification codes, see virtual numbers.
Czech Republic eSIM on O2 and Vodafone
5GMobile data for a long weekend in Prague or a semester in Brno, in the country also called Czechia. Each plan counts days from its first connection there.
The unlimited plan is the day pass we feature for the Czech Republic: after its daily full-speed allowance it keeps you connected at a lower speed, and it is billed per day for the days you choose. Fixed plans are one price for the term shown. Nothing on this page is an estimate.
How to get mobile data in the Czech Republic
Set it up at home the night before. Your eSIM waits quietly until you arrive.
Pick eSIM plan
Choose how long you are there. The day pass is billed per day, so the term is yours to set.
Pay, then scan
Charged from your balance, which you top up with crypto. Your QR code is in your dashboard once the order is paid.
Turn it on when you arrive
Turn on data roaming for your SIMAREA plan when you arrive, and it joins a partner network.
What to know about an eSIM for the Czech Republic
The specifics that decide whether a travel eSIM is useful once you're actually there.
More than one network
Every plan here lists more than one partner network. If one gets weak, your phone can switch to another.
Set up before you go
No SIM card store, no passport check. Install it at home, then turn on data roaming for it when you arrive.
Hotspot sharing
Share your internet with a laptop or a friend, if your plan and phone allow it.
Keep your own number
The eSIM is just for internet. Your normal SIM still receives calls and important bank codes. You can use both at once.
Keep using the same eSIM
Staying longer? Top up the same plan with more data from your dashboard. No need for a new QR code.
If it does not work
Not installed or connected yet? Ask for a refund within 30 days of buying it. Installed but not working on any of its networks? Support helps, and refunds you if it cannot be fixed.
Czech Republic eSIM: O2 and Vodafone, no T-Mobile
Every Czech plan sold here connects to O2 and Vodafone, the day pass included, and the catalog marks 5G on both. T-Mobile, the third big Czech network, isn't on them. It appears on one kind of plan only: the 31-day Europe eSIM rows of 10, 20, or 50 GB, which start counting at installation and can't be topped up.
Whichever network you're on, France, the Netherlands, and the UK are the listed exits, so a site sees an address in one of them and not a Czech one.
A stay in Prague longer than a month
Up to a month, the steps are small: 1 GB for 7 days, 2 or 3 GB for 15 days, and 3, 5, 10, or 20 GB for 30 days. The next Czech term is 50 GB for 180 days, with nothing in between. A top-up won't bridge that gap, since it adds data and not days. For two or three months, you have three options:
- The 180-day plan, leaving the end of the term unused.
- A second 30-day plan once the first one ends.
- A 90-day row: the Europe eSIM sells 20 or 50 GB for 90 days, and Global 130 sells 20 GB. All of them name the Czech Republic.
Prague with Vienna, Budapest, or Kraków
A Czech plan names the Czech Republic alone, so the next country takes something else. Austria, Germany, Hungary, Poland, and Slovakia sit on every Europe row alongside the Czech Republic, so the difference between rows is what happens on the Czech side:
- 34-, 35-, and 41-country rows: O2 and Vodafone, both marked 5G, except the 50 GB row for 30 days, which shows no 5G.
- 33-country rows: 5G on O2 but not on Vodafone, with an exit in Belgium.
For a short hop, add a plan for that country next to this one, such as Austria or Slovakia.
Czech Republic eSIM questions
Is a Czechia eSIM different from a Czech Republic eSIM?
No, it's one country under two names. The catalog uses Czech Republic, so look for that name on plan and country lists.
Is the Czech day pass unlimited?
You get 1 GB a day at full speed, then 512 Kbps until the day resets. The Europe day pass has the same daily 1 GB but slows further, to 384 Kbps.
Does it include a Czech phone number?
No. It's a data eSIM: your own SIM keeps your number and your calls. A rented number that receives SMS is a separate product, listed under virtual numbers.
What if neither O2 nor Vodafone connects?
Check that data roaming is on for the eSIM, then try choosing each network by hand in your phone's settings. If the eSIM works on neither, contact support: they fix it or refund it.
Can I set it up at home before going to Prague?
Yes. No Czech plan counts a day until it first connects in the Czech Republic, and an unused plan stays valid for 180 days. Be sure of your plan first, because once an eSIM is installed, it can no longer be refunded on request. Before that, the window is 30 days from purchase.
