O2 Czech Republic

Operating within a highly competitive, saturated telecommunications market, O2 Czech Republic stands out by combining the most affordable fixed internet services, a superior mobile network, and exclusive television content. While mobile telecommunications services are its main revenue stream, O2’s fixed internet covers 99% of the country’s inhabited territory, positioning it as the largest internet provider for both businesses and households. O2 is also one of the country’s biggest providers of hosting, cloud services, managed services, and ICT.  

Developing and offering pioneering telecommunications services such as cybersecurity and financial services, including device insurance and mobile travel insurance, is a hallmark of O2’s approach. Virtual operators also offer their services via the O2 mobile network. 

In collaboration with Air Bank, O2 Czech Republic introduced Unity, integrated offering for customers of both companies that allows them to get the best possible experience and value while managing their telecom and financial needs in one place. This increases convenience and loyalty while providing a platform for cross-selling opportunities. 

Unity, along with several other customer-focused initiatives – such as the doubling of unlimited data days on mobile plans in 2024 – reflects a broader commitment to care embodied in the new creative concept, “More of Life.” This concept centres on enhancing the customer experience and leveraging technology in meaningful and efficient ways.  

At the end of 2024, the company had over six million mobile clients and over a million fixed broadband users. O2 TV has solidified its position as the most popular IPTV service in the Czech Republic, with almost a million O2 TV users at the end of 2024. Oneplay, a partnership between O2 TV and CME’s Voyo streaming platform introduced in March 2025, marks the next evolution of O2 TV. It unifies streaming and live television into a single, user-friendly service with a broader content library and enhanced features. 

Other areas O2 is developing include artificial intelligence and big data technology, both handled by its Dataclair.ai—Artificial Intelligence Centre. O2 is also active in smart city infrastructure and autonomous mobility of the future.
