Prague, 21. 5. 2026 – The Czech Telecommunication Office published its 2025 Annual Report, which summarises its main activities in the areas of regulation of electronic communications, postal services, digital services and preparation for artificial intelligence supervision. The report also includes data on market developments, including continued growth in mobile data consumption and the expansion of next-generation networks.
The total volume of mobile data transferred in 2025 reached approximately 2,16 thousand PB, which represents a year-on-year increase of less than 25%. Average monthly data consumption per SIM data card increased to 15.1 GB (compared to 12.5 GB in 2024). The total number of active SIM cards was close to 16 million at the end of 2025.
In the area of digital regulation, CTU continued to prepare for the role of national coordinator under the DSA. The Office established the Advisory Panel, launched the information website DSA Česko and introduced a self-identification calculator for determining the obligations of service providers.
