Everything you need to know about using eSIMs in Czech Republic
Czech Republic offers more than 140 eSIM providers and over 8, 700 prepaid data plans, giving travelers a wide variety of options to suit their data needs.
Unlimited data eSIM plans are available for the Czech Republic from several providers. Firsty offers a one‑day unlimited plan for free, but the bandwidth is limited to 256 kilobits per second and the service includes advertisements. Yoho Mobile, abesteSIM, Roamify, MicroEsim, Truely and Yesim all list unlimited data for validity periods ranging from one day to ten days, with typical prices between about two dollars and twenty dollars per plan. All of these plans allow tethering; however, traffic may be throttled, typically to a maximum speed of around five megabits per second. The price range for unlimited data eSIMs across these carriers therefore falls roughly between zero and roughly twenty‑nine dollars, giving travelers a variety of affordable options to choose from.
In the Czech Republic, the primary Mobile Network Operators (MNOs) are:
O2 Czech Republic: A major integrated operator providing extensive mobile and fixed-line services, including 2G, 3G, 4G, and 5G networks.
T-Mobile Czech Republic: A subsidiary of Deutsche Telekom, offering comprehensive mobile services with widespread coverage across the country.
Vodafone Czech Republic: Part of the Vodafone Group, delivering a range of mobile services with a significant customer base and network reach.
In addition to these MNOs, the Czech Republic hosts several Mobile Virtual Network Operators (MVNOs) that provide mobile services by leasing access from the major carriers. Notable local MVNOs include SAZKAmobil and Lama mobile, both of which utilize Vodafone's network infrastructure. It's important to note that most travel eSIMs rely on MNO infrastructure rather than MVNOs.
Travel eSIM plans that include a phone number and SMS are available for trips to Czech Republic, offered by nine independent providers. Prices begin as low as $4 for a 1 GB 7‑day GlobaleSIM plan and scale up to around $120 for 500 GB 90‑day options. Validity periods range from 7 days to 90 days for most plans, with a few longer‑term packages available up to 365 days.
The plans that supply a local Czech number (dialing code +420) are offered by Airalo and SimOptions, and they support both inbound and outbound voice calls and SMS. Other providers issue numbers from foreign codes – +33 (France), +1 (United States), +34 (Spain), and +44 (United Kingdom) – which give you a non‑local mobile number but still allow inbound and outbound voice and SMS as specified in each plan’s telephony features. All listed options provide SMS capability and enable the user to make and receive calls regardless of the number’s country code.
