The Czech Republic (Czechia) – known for its beer, art & culture.
It is also a relatively affordable travel destination in Central Europe.
Just like neighboring countries, the Czech Republic is also famous for skiing.
But what can you do in the country besides skiing? A lot.
Plenty of churches and cathedrals can be seen and visited.
The Národní Muzeam (Museam) is a must see too.
Let's not forget about the stunning castles, like Karlštejn Castle.
It should be illegal to be bored in the Czech Republic.
One thing that will rarely be cheap, including in the Czech Republic, is international roaming.
It can be crazy expensive.
That is why you should get local SIM cards when traveling, like a Czech one, so that you can enjoy local rates.
However… SIM cards are not cheap in the Czech Republic, but they are not crazy expensive either (looking at you, Cuba).
You can get a Czech SIM card for 150 CZK (7.14 USD) from T-Mobile, 179 CZK (7.40 USD) from O2 & 200 CZK (9.40 USD) from Vodafone in their stores and from resellers, like newsstands. The MVNOs sell SIM cards for between 100 CZK (4.70 USD) and 500 CZK (23.45 USD). Vodafone also sells SIM cards at Václav Havel Airport Prague (PRG).
While there are many countries with higher SIM card prices, many have much cheaper ones (some are free to almost free).
One amazing thing about the Czech Republic is that you have a lot of choices because of the number of MVNOs in the Czech market.
In this guide, I will go over everything you need to know about buying a SIM card in the Czech Republic. Let's do this.

Table of Contents
Can You Buy a SIM Card in the Czech Republic?
Anyone living in or visiting the Czech Republic can buy a Czech SIM card from T-Mobile, O2, Vodafone, BLESKmobil, COOP Mobil, Kaktus, Mobil.cz, OpenCall, Oskarta, SAZKAmobil & Tesco Mobile with no restrictions.
Your phone has to support the frequencies used in the Czech Republic.
Furthermore, your phone needs to be unlocked (SIM-lock free) to use a Czech SIM card.
Where Can You Buy a SIM Card in the Czech Republic?
You can get a Czech SIM card in T-Mobile, O2 & Vodafone stores. Resellers, like grocery stores and gas stations, also sell SIM cards (especially for BLESKmobil, COOP Mobil, Kaktus, Mobil.cz, OpenCall Mobile, Oskarta, SAZKAmobil & Tesco Mobile). They are also available at Václav Havel Airport Prague (PRG – Vodafone only).
You can expect to pay the following for Czech SIM cards:
- T-Mobile Czech Republic: 150 CZK, 200 CZK & 469 CZK
- O2 Czech Republic: 179 CZK & 299 CZK (regular & data-only for the same price)
- Vodafone Czech Republic: 200 CZK (regular), 800 CZK (data-only) & 1299 CZK (data-only)

Can You Use Your Phone in the Czech Republic?
The Czech Republic uses GSM technology for mobile communications. CDMA phones will not work in the Czech Republic. If your phone has a SIM card slot, then it supports GSMA (99% of the phones do support GSM nowadays).
Traditional European frequencies are used in the Czech Republic, which are mostly used in ITU Regions 1 and 3 (Africa, Asia (including the Middle East), Europe & Oceania).
The Americas (North-, Central– & South America + the Caribbean – ITU Region 2) use American frequencies, which differ from the European ones.

If you bought your phone in Africa, Asia, Europe, or Oceania (ITU Regions 1 and 3), you should not experience any issues with using your phone in the Czech Republic.
If you purchased your phone in the Americas (ITU Region 2) and have a low/medium-end device (without Tri-Band or Quad-Band) support, then there is a possibility you cannot use your phone when in the Czech Republic or can only use slower networks (3G or 2G).
If you have a medium/high-end device with Tri-Band or Quad-Band support, you can use your phone in the Czech Republic (to some extent) – also on 4G/LTE and 5G NR.
Mobile Operators, Networks & Frequencies in the Czech Republic
The Czech Republic has three mobile operators and eight mobile virtual network operators (MVNOs) offering prepaid services easily accessible to travelers:
- T-Mobile Czech Republic
- O2 Czech Republic
- Vodafone Czech Republic
- BLESKmobil (O2 Czech Republic MVNO)
- COOP Mobil Czech Republic (Vodafone Czech Republic MVNO)
- Kaktus (T-Mobile Czech Republic)
- MOBIL.CZ (T-Mobile Czech Republic)
- OpenCall Mobile (O2 Czech Republic MVNO)
- Oskarta (Vodafone Czech Republic MVNO)
- SAZKAmobil (Vodafone Czech Republic MVNO)
- Tesco Mobile Czech Republic (O2 Czech Republic MVNO)
The following frequencies are used in the Czech Republic:
- 2G: 900 MHz & 1800 MHz
- 3G: N/A – shut down in November 2021 – (mostly) reframed for 4G/LTE
- 4G/LTE: 800 MHz (Band 20), 900 MHz (Band 8), 1800 MHz (Band 3), 2100 MHz (Band 1) & 2600 MHz (Band 7)
- 5G NR: 1800 MHz (n3), 2100 MHz (n1) & 3500 MHz-3700 MHz (n78)
You can learn more about frequencies in the video below.
To check whether your phone will work in the Czech Republic, check out this page by Kimovil or this one by Will My Phone Work (outdated, unfortunately, but extremely user-friendly – useful for phones launched in or before 2019. It does not check for 5G NR compatibility).
Again, make sure your phone is unlocked. Otherwise, you will not be able to use any SIM card except the one from your home operator (meaning you have to roam internationally or buy another unlocked phone that does support the frequencies listed above).
If you want to learn how international roaming works, this guide explains it in-depth. If you wonder why it is often so expensive to roam, this article explains the hidden reason they do not want you to know.
VoLTE & VoWiFi in the Czech Republic
Both VoLTE (Voice over LTE (4G) – also known as HD Voice) and VoWiFi (Voice over WiFi – also known as WiFi calling) are available in the Czech Republic. All mobile operators in the Czech Republic offer both VoWiFi. VoLTE is not available with Vodafone Czech Republic. Its MVNOs offer VoWiFi only.
This means that your phone does not have to downgrade to 2G (no 3G in the Czech Republic anymore) when making a call (unlike mobile operators that do not support VoLTE) with T-Mobile Czech Republic and O2 Czech Republic.
Some MVNOs also offer both VoLTE and VoWiFi. Others only offer VoWiFi (especially Vodafone Czech Republic MVNOs). While others offer neither.
The following mobile operators and MVNOs offer VoLTE and VoWiFi in the Czech Republic:
- T-Mobile Czech Republic
- O2 Czech Republic
- Kaktus Czech Republic
- MOBIL.CZ
- OpenCall Czech Republic
The following mobile operators and MVNOs offer VoWiFi only in the Czech Republic:
- Vodafone Czech Republic
- COOP Mobil Czech Republic
- Oskarta
- SAZKAmobil
BLESKmobil and Tesco Mobile Czech Republic offer neither VoLTE or VoWiFi.
This means that when you make a call, your phone will downgrade to 2G (there is no 3G in the Czech Republic anymore) instead of staying connected to 4G/LTE.
This is also why you often cannot use mobile data while calling if not connected to WiFi.
VoWiFi is, as the name implies, calling on a WiFi connection as opposed to on a cellular network.
5G NR in the Czech Republic
Commercial 5G NR has been available in the Czech Republic since October 2020. It is available on the T-Mobile, O2 & Vodafone networks. The Mobile Virtual Network Operators (MVNOs) do not have access to 5G NR (yet).
Best SIM Card in the Czech Republic
Best eSIM in the Czech Republic
T-Mobile Czech Republic, O2 Czech Republic, Vodafone Czech Republic & MOBIL.CZ offer eSIM to prepaid customers.
Vodafone Czech Republic is rather vague on whether it allows prepaid customers to use eSIM or not.
Originally, I mentioned that I would confirm if they are also available for prepaid customers after visiting the Czech Republic again in January 2022.
Well… I forgot to ask 💀 – but you still have other options.
However, you can also get a travel eSIM from various eSIM providers.
The list below is not exhaustive – many more providers have eSIMs for Czech Republic.
But these are the ones I have tried and had pleasant experiences with.
Moreover, they are reasonably priced, which I find very important (you will not see me recommending an eSIM I would not buy myself).
So here are the ten best eSIMs for Czech Republic:
- Airalo's O2 Stay in Touch Czech Republic eSIM with one 10 GB option (best value for money)
- Airalo's Eurolink Europe eSIM with six choices between 1 GB and 100 GB (best value for money when also visiting other European countries) – read my ongoing Airalo Eurolink eSIM review too!
- Holafly Czech Republic eSIM with unlimited data for 5 to 90 days (truly unlimited data plans at premium prices)
- Nomad Czech Republic eSIM with 11 choices between 1 GB and 20 GB (switches to the best network, allowing for excellent reception at all times)
- Holafly Europe eSIM with unlimited data for 5 to 60 days (truly unlimited data plans when also visiting other European countries at premium prices)
- Nomad Europe eSIM with 13 choices between 1 GB and 40 GB (the best of both worlds in terms of pricing and performance)
Because this is the SIM card buying guide for Czech Republic, I will not spend too much time about travel eSIMs here and throughout this guide (but I will still do here and there).
If you want to learn more about the best eSIMs for Czech Republic, you better check out my Czech-Republic eSIM buying guide.
It is as helpful and comprehensive as this guide but about eSIMs instead 😜.

SIM Card Registration in the Czech Republic

EU Roaming in the Czech Republic

The Czech Republic is part of the European Union (EU).
Since June 2017, those with EU/EEA (European Economic Area) SIM cards can roam for free in other EU/EEA nations, including the Czech Republic.
This means that, in the majority of cases, you do not need to purchase a Czech SIM card if you already have an EU/EEA SIM card because you can roam without additional costs.
However, conditions do apply. Mobile operators in some countries may impose a roaming Fair Use Policy (FUP).
In countries where local mobile data rates are extremely low (such as in the Baltics and the Nordics), mobile operators may still charge you for roaming in the EU/EEA.
Be sure to head over to the international roaming page to learn whether your mobile operator offers free roaming while in the Czech Republic or if restrictions apply.
Roaming in the EU with Czech SIM Cards

The Czech Republic and the Czech mobile operators have fully adopted the roam like at home regulations principles early on.
Unlike most EU/EEA mobile operators that impose EU/EEA roaming caps, none of the Czech mobile operators have such caps.
However, the standard Fair Use Policy applies where you should not be roaming over 50% of the time over a four-month period.
If you do so, EU roaming rates will apply.
You are then better off buying local prepaid SIM cards in other EU nations.

Currency in the Czech Republic

The Czech Republic uses the Czech Koruna with the symbol CZK (which will be used throughout this guide).
However, prices are often listed as Kč. For example, 25 CZK = Kč 25.
For reference, below are some exchange rates between CZK and USD (US Dollars):
- 1 CZK = 0.05 USD
- 10 CZK = 0.45 USD
- 100 CZK = 4.70 USD
- 1000 CZK = 46.95 USD
- 10 000 CZK = 469.40 USD
For up-to-date CZK:your currency (let's say EUR – Euro) exchange rates, use the Wise Currency Converter tool.
While the Czech Republic is in the European Union, it is not part of the Euro Zone.
That is why it still uses its own currency.

Also, do not attempt to pay with Euros in the Czech Republic, as almost no merchant will accept it – certainly not the mobile operators.
If your credit/debit card charges you foreign exchange fees, get yourself a Wise Borderless Account and Debit Card.
Their fees are MUCH lower than banks and credit card companies charge you (and Wise is transparent about their fees, unlike banks).
I have saved literal THOUSANDS of Australian Dollars and Euros, my main currencies, when using Wise abroad when traveling compared to my debit and credit cards.
Czech Prepaid SIM Cards
Below, I will guide you through T-Mobile Czech Republic, O2 Czech Republic, Vodafone Czech Republic, BLESKmobil, COOP Mobil Czech Republic, Kaktus Czech Republic, MOBIL.CZ, OpenCall Czech Republic, Oskarta, SAZKAmobil & Tesco Mobile Czech Republic, and go through:
- Background information
- Mobile coverage
- SIM card types, prices & availability
- Recharge / top-up information
- Combo plans, data plans & special packs (such as social media packs)
With that being said, let’s see what the Czech Republic has to offer to us.
T-Mobile Czech Republic

T-Mobile Czech Republic, just T-Mobile, is the largest mobile operator in the Czech Republic.
Telekom, by Deutsche Telekom (from Germany), is active in Europe (as Telekom and T-Mobile) and the United States (as T-Mobile).
T-Mobile uses the following frequencies:
- 2G: 900 MHz & 1800 MHz
- 3G: N/A – shut down in November 2021 – (mostly) reframed for 4G/LTE
- 4G/LTE: 800 MHz (Band 20), 1800 MHz (Band 3), 2100 MHz (Band 1) & 2600 MHz (Band 7)
- 5G NR: 1800 MHz (n3), 2100 MHz (n1) & 3700 MHz (n78)
This is what you will learn about T-Mobile:
* Coverage
* How to Get a T-Mobile SIM Card & SIM Card Price
* Topping Up Options & Methods + Balance Check
* Plans & Packages
* APN/Internet Settings
Coverage – T-Mobile Czech Republic
T-Mobile has extensive coverage throughout the Czech Republic.
4G/LTE is available almost anywhere throughout the country.
Below is T-Mobile's coverage map produced by Speedtest:
SIM Card Price – T-Mobile Czech Republic
You can buy a T-Mobile SIM card, called Twist Kartu, for 150 CZK, 200 CZK, or 469 CZK credit in T-Mobile stores and from resellers, including grocery stores, kiosks & gas stations. T-Mobile SIM cards are not sold at Václav Havel Airport Prague (PRG).
The following three T-Mobile SIM cards are available:
Price | SIM Card | Credit | Data | Local Minutes | Local SMS | Bonus Validity |
---|---|---|---|---|---|---|
150 CZK | Twist 50 a 50 | 100 CZK | 100 MB | 50 minutes | 50 SMS | 1 day |
200 CZK | Twist 3 GB Dat | 100 CZK | 3 GB | N/A | N/A | 30 days |

- Find out how much SIM cards cost in every country, including data-only SIM cards and tourist SIM cards, offered by each mobile operator + information about starter benefits (lookup tool)

It is also possible to get a T-Mobile eSIM for the same price as a regular SIM card.
Currently, T-Mobile does not have a list of devices that can use its eSIM.
But I suspect the standard Google Pixel, iPhone, Huawei (Mate) P40 (Pro) & Samsung (Galaxy (Note))/Flip can use T-Mobile's eSIMs.
Therefore, if you wish to get an eSIM for Czech Republic without personal detail capturing, you can get unlimited data eSIMs from Holafly (eight options):
- Unlimited/5 days – very popular with Phone Travel Wiz readers
- Unlimited/7 days
- Unlimited/10 days
- Unlimited/15 days
- Unlimited/20 days – most popular with Phone Travel Wiz readers
- Unlimited/30 days
- Unlimited/60 days
- Unlimited/90 days
Note: Phone Travel Wiz reader popularity ranking was updated in March based on data up to the 7th of March.

The best part is that you can get 5% off using code PHONETRAVELWIZ on each Holafly eSIM purchase!
No idea what or who Holafly is? Check out my Holafly review, where I share my hands-on experience after using its eSIMs in more than ten countries over two years.

If you plan on visiting other neighboring European nations, consider the Airalo Eurolink eSIM to be used in 39 European countries with six variants:
- 1 GB/7 days
- 3 GB/30 days – very popular with Phone Travel Wiz readers
- 5 GB/30 days – most popular with Phone Travel Wiz readers
- 10 GB/30 days – very popular with Phone Travel Wiz readers
- 50 GB/90 days
- 100 GB/180 days
Note: Phone Travel Wiz reader popularity ranking was updated in May based on data up to the 17th of May (2023 data only).

Do you think the map above is nice, but you want a country list instead (because you do not recognize the countries on a map🗿)? You can find it in my Airalo review!
By the way, you get free 5G NR access in 22 of the 39 supported countries!
I have used the Airalo Eurolink eSIM in 11 countries so far, and my goal is to test it in all supported countries.
- Be sure to check out my Airalo Eurolink eSIM review for my insights!

Many more travel eSIMs will perform well in Czech Republic.
You can read about them in my Best Czech Republic eSIMs Compared guide for an in-depth comparison.

Note that T-Mobile offers VoLTE (Voice over LTE (4G)) if your phone supports it and you have enabled it in the settings.
Oh, you can also use VoWiFi (Voice over WiFi).

Vodafone Czech Republic

Vodafone Czech Republic, just Vodafone, is the smallest mobile operator in the Czech Republic.
However, it has the best overall network performance.
Vodafone, as a company, is active in Africa (mostly as Vodacom), Asia, Europe, the Middle East & Oceania.
Vodafone uses the following frequencies:
- 2G: 900 MHz & 1800 MHz
- 3G: N/A – shut down in November 2021 – (mostly) reframed for 4G/LTE
- 4G/LTE: 800 MHz (Band 20), 900 MHz (Band 8), 1800 MHz (Band 3), 2100 MHz (Band 1) & 2600 MHz (Band 7)
- 5G NR: 1800 MHz (n3), 2100 MHz (n1) & 3700 MHz (n78)
This is what you will learn about Vodafone:
* Coverage
* How to Get a Vodafone SIM Card & SIM Card Price
* Topping Up Options & Methods + Balance Check
* Plans & Packages
* APN/Internet Settings
Coverage – Vodafone Czech Republic
Vodafone has extensive coverage throughout the Czech Republic.
It also has the most extensive 5G NR coverage.
Below is Vodafone's coverage map produced by Speedtest:
However, click here to see Vodafone's official coverage map.
SIM Card Price – Vodafone Czech Republic
You can buy a Vodafone SIM card for 200 CZK with 200 CZK credit in Vodafone stores and from resellers, including grocery stores, kiosks & gas stations. The Data SIM for Visitors is sold for 800 CZK/1299 CZK with 10 GB/20 GB of data in Vodafone stores only. Vodafone SIM cards are also sold at Václav Havel Airport Prague (PRG).
While the data-only SIM cards are called Data SIM for Visitors, they are sold to anyone – including Czech citizens and foreigners living in the Czech Republic.
But… they are certainly not the cheapest options for those actually living in the country (you are better off with postpaid plans).
Anyway, below is an overview of the two Data SIM for Visitor SIM cards:
Price | Data | On-Net Minutes | Validity |
---|---|---|---|
800 CZK | 10 GB | Unlimited | 30 days |
1299 CZK | 20 GB | Unlimited | 30 days |
Note that the Data SIM for Visitors SIM cards are for local use only – they cannot be used for EU/EEA roaming.

You may have to make a call or send an SMS to activate your Vodafone SIM card.
- Find out how much SIM cards cost in every country, including data-only SIM cards and tourist SIM cards, offered by each mobile operator + information about starter benefits (lookup tool)

It is also possible to get a Vodafone eSIM for the same price as a regular SIM card.
However, it is unclear if eSIMs are available for prepaid customers too.
I initially wrote that I would confirm this after visiting the Czech Republic again mid-January (2022), but I forgot to ask 💀.
Therefore, if you wish to get an eSIM for Czech Republic without personal detail capturing, you can get unlimited data eSIMs from Holafly (eight options):
- Unlimited/5 days– very popular with Phone Travel Wiz readers
- Unlimited/7 days
- Unlimited/10 days
- Unlimited/15 days
- Unlimited/20 days – most popular with Phone Travel Wiz readers
- Unlimited/30 days
- Unlimited/60 days
- Unlimited/90 days
Note: Phone Travel Wiz reader popularity ranking was updated in March based on data up to the 7th of March.

The best part is that you can get 5% off using code PHONETRAVELWIZ on each Holafly eSIM purchase!
No idea what or who Holafly is? Check out my Holafly review, where I share my hands-on experience after using its eSIMs in more than ten countries over two years.

If you plan on visiting other neighboring European nations, consider the Nomad Europe eSIM to be used in 31 or 35 European countries, depending on the plan, with thirteen variants:
- 1 GB/7 days (31 countries)
- 1 GB/7 days (35 countries)
- 3 GB/15 days (31 countries)
- 3 GB/30 days (35 countries)
- 5 GB/30 days (31 countries) – very popular with Phone Travel Wiz readers

- 20 GB/30 days (35 countries)
- 30 GB/30 days (35 countries)
- 40 GB/30 days (35 countries)
Note: Phone Travel Wiz reader popularity ranking was updated in February based on data up to the 7th of February.

Remember to use code ADU123 for 3 USD/2.70 EUR/2.40 GBP/4.05 CAD off your first Nomad purchase!
I have used the Nomad Europe eSIM in eight countries so far, and my goal is to test it in all supported countries.
- Be sure to check out my Nomad Europe eSIM review for my insights!

Many more travel eSIMs will perform well in Czech Republic.
You can read about them in my Best Czech Republic eSIMs Compared guide for an in-depth comparison.

Note that Vodafone offers VoLTE (Voice over LTE (4G)) if your phone supports it and you have enabled it in the settings.
Oh, you can also use VoWiFi (Voice over WiFi).

These are the PAYG rates:
- 3 CZK for 10 MB

- 3 CZK for 1 SMS
If you spent the 30 CZK on calls or SMS, you would get 400 MB for free for the remainder of the day.
If 30 CZK was entirely spent on data, you would get only 300 MB for free (or 400 MB minus the PAYG data usage).

Packages, Plans, Bundles & Offers – Oskarta
Oskarta has no (data-)featured prepaid plans. Instead, only Pay As You Go rates are available.
For data, you will be charged 1 CZK for 1 MB.
Normally, I would not even include a mobile operator (or MVNO for that matter) with such outrageous rates.
However, if you use more than 77 MB (77 CZK) but less than 1 GB, you will only be charged 77 CZK.
This 1 GB will stay valid for one month.
If you go over your 1 GB allowance, you will be charged another 77 CZK for another 1 GB for 1 month.
77 CZK for 1 GB of data is below average in the Czech Republic, so it is a worthy option to consider.
