The Czech Republic has 3 network operators:

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

Since a few years MVNOs are starting up: COOP mobile, TESCO mobile 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:

  • 800/900/1800/2100/2600 MHz on Vodafone: available for all users
  • 800/1800 MHz on O2 and T-Mobile: available for all users

Vodafone has the best 4G coverage in 2015. 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.
