[Updated for 2024] A must-see for travelers to the Czech Republic! A complete guide to recommended SIM cards!


Planning a trip to the Czech Republic? Dobrý den! Are you preparing for your trip? The Czech Republic has many attractive places, including historical buildings such as Prague Castle and Charles Bridge, the beautiful cityscape of Cesky Krumlov, which is registered as a World Heritage Site, and one of the world's leading beer cultures. A smartphone is essential for a comfortable trip, whether it's for local navigation, searching for restaurants, sharing photos, or updating social media. Here we will show you how to choose and use the best SIM card for your stay in the Czech Republic.

1. Communication environment and SIM card selection

Checking coverage and communication quality

When choosing a SIM card for the Czech Republic, it's important to make sure it has good coverage in the areas you plan to visit. We recommend a local SIM card, which will provide reliable connections in urban areas such as Prague, as well as popular tourist destinations such as Karlovy Vary and Cesky Krumlov.

Select your data plan and speed

4G and LTE networks are common in the Czech Republic. 5G is becoming more and more available in urban areas. Wi-Fi is also available in restaurants and cafes in urban areas. Choose a plan that suits your travel style, taking into consideration the amount of data and communication speed you need. If you watch a lot of videos, upload photos to SNS, or download a lot of data, a large-capacity data plan is suitable.

Choose your rate plan

Choose a plan that offers the best cost performance depending on the length of your stay and the amount of data you will use. If you are staying for a short period of time, a daily plan is convenient. On the other hand, if you are staying for a long period of time or have a lot of data usage, we recommend a monthly plan.

2. Tips for choosing a SIM card in the Czech Republic

Check your SIM card type

It is most important to choose a SIM card that is compatible with your device. In addition to traditional physical SIM cards (standard SIM, micro SIM, nano SIM), the latest devices also offer eSIMs. Before traveling, it is important to check which type of SIM card your smartphone supports.

3. How do I get a SIM card in the Czech Republic?

Where to buy a SIM card

You can get SIM cards at mobile phone specialty stores and kiosks in Prague International Airport and major city centers. When purchasing a SIM card, you may be required to show identification (passport), so it's a good idea to bring it with you. It's also important to check that your smartphone can connect to the Internet before leaving the store.

It is important to check in advance how to obtain a SIM card, the compatibility of the smartphone you will be using, and the documents required for purchase. You can obtain a SIM card at the airport or a mobile phone specialty store in the city. Activation may take some time, so plan well in advance.

Choose your data plan

When using data in the Czech Republic, if you use the smartphone you brought from Japan, you may incur high international roaming charges. It is important to check the data volume and speed limits of your current smartphone plan in advance and choose a plan that suits your usage pattern.

Check the SIM card size

Find out what size SIM card your phone needs - most commonly a nano SIM , but you might need a different size - and also make sure you have a pin to replace your SIM card, and a way to store your current SIM card.

Check the SIM lock status of your smartphone

If your smartphone is SIM-locked by a specific carrier, you may not be able to use a local SIM card. Please check the SIM-lock status of your smartphone before traveling and see if it can be unlocked.

■VOYAGEESIM FOR Europe review

I used it in Finland, Italy, Spain and the UK, and it was comfortable and smooth in every country
. "-May 14, 2024-


"This is my first time using this comfortable internet environment. I used the 5GB, 10-day plan for an 8-day tour of Germany, the Czech Republic, and Hungary.
I downloaded the app onto my iPhone in advance in Japan as instructed in the manual, and when I arrived at Munich Airport, I switched to the eSIM and was able to use it immediately.
I was able to connect to 5G or 4G networks without any problems in any country, and had a comfortable internet environment. The signal was weak near Neuschwanstein Castle in Germany, and I couldn't connect, including to other service users, but otherwise there were no problems at all.

Compared to renting Wi-Fi, it is very convenient that you don't need to charge your device or carry the Wi-Fi itself, and you can easily check the remaining charge at any time. It is also cost-effective, and I would like to use it when traveling abroad in the future. " - March 19, 2024 -


"It saved me.
I bought it with the intention of using it in Finland, Portugal, and London, including transit points. I had trouble connecting at first, but after tweaking the settings, it finally connected. I would like to use it again. " - May 11, 2024 -
