O2 Czech Republic a.s. is a Czech telecommunications company headquartered in Prague. It is one of the three mobile network operators in the Czech Republic, alongside T-Mobile Czech Republic and Vodafone Czech Republic, and also provides fixed internet, television and digital services. The company is wholly owned by PPF Group and uses the O2 brand under licence.
The company developed from the former Czech telecommunications operator Český Telecom and mobile operator Eurotel, which were brought together under the O2 brand in 2006. PPF acquired control of the company in 2014. In 2015, its telecommunications infrastructure business was separated into the newly established CETIN, leaving O2 primarily focused on retail telecommunications and digital services. O2 became wholly owned by PPF and was delisted from the Prague Stock Exchange in 2022.
