The Czech Republic has 3 GSM-based network operators:

  • Vodafone (British-owned)
  • O2 (owned by PPF)
  • T-Mobile (owned by German Deutsche Telekom)

A fourth operator U:fon is on GSM-incompatible CDMA reaching 90% of the Czech populationon up to 3.1 Mbps speed. They aim to start 4G/LTE on 400 MHz which is also incompatible with all usual GSM devices. That's why they aren't mentioned any further.

Since a few years already more than 50 MVNOs have started up: COOP mobile, TESCO mobile,, OpenCall, Kaktus, and SAZKA mobile are given as examples for good data rates, but there are more on the market.

2G/GSM covers all of the country on 900 and 1800 MHz like in the rest of Europe. 3G/UMTS is on 2100 MHz in most of the areas. 4G/LTE is on 800 MHz, 1800 MHz, 2100 MHz and 2600 MHz available to all users. The former LTE coverage on 900 MHz of Vodafone has migrated to 800 MHz now.

Vodafone has the best 4G coverage in 2016. According to the Czech Telecommunication Office 93% of population on 76% of the territory get Vodafone's LTE. O2 and T-Mobile build up their LTE together and reach 82% on 43% in 2015. O2 and T-Mobile also have net sharing agreements for 2G and 3G practically everywhere outside of Prague and Brno. That's why their footprint is almost the same.

SIM cards are available in the stores of the network operators or in many supermarkets without registration. Recharge vouchers can be bought at many kiosks, post offices and petrol stations.

Unlike in many other European countries, you will lose all credit on a Czech SIM card, if you don't top-up your balance periodically; periodic usage is not enough. A very effective way to use up surplus credit on a Czech SIM card is to spend it on premium SMS for tickets on public transport in Prague. Tickets purchased this way cost the network's standard SMS charge plus the price of the ticket.

Vodafone Edit


Vodafone is the smallest of the 3 nationwide network providers by customers numbers in the Czech Republic. As of 2015 it has the best coverage of combined 3G and 4G. LTE runs on 5 different frequencies covering 92% of population: on 800, 1800, 2100 and 2600 MHz. LTE on 900 MHz has now migrated to 800 MHz. 2100 MHz is used in some cities but supported by few phones sold in Europe (see Network Compatibility of common phones). If you are not sure of the frequencies supported by your phone, you can rent Vodafone Hotspot for Visitors, which supports all the frequencies in Czech, see here. For coverage map see here. Vodafone's LTE is called "Turbo Internet" and is available without surcharges.

Start-up costs Edit

A prepaid Czech Vodafone startup SIM cards cost 200 CZK and come with an equal amount of credit. The default PIN is 1234 and the SIM is automatically activated when placed in your phone. The SIM is available in Vodafone stores (store locator) and kiosks. If you buy a SIM at the Vodafone store, you may activate any special service such as data right away.
Top-ups are not possible online with a non-Czech credit card, but you may pay with credit card at some shops or ATMs. Vouchers are sold by post offices, kiosks, supermarkets, betting halls etc. for CZK 250, 500 and 1200. It doesn't matter which prepaid line from Vodafone you buy, as long as your are using data only as the packages are all the same for prepaid.
