Background

CETIN is part of CETIN Group, one of the largest telecommunications networks across Central and Eastern Europe.

Driven by innovation and true entrepreneurship, CETIN Group companies were formed due to a successful structural separation of infrastructure business from O2 in Czechia in 2015, and Yettel branded operators in Hungary, Serbia, and Bulgaria in 2020.

Network

The first mobile network in Serbia launched in 1994, was based on network infrastructure owned by CETIN.

Nowadays Yettel's 2G, 3G, 4G and pioneering 5G mobile network services are fully powered by CETIN network and expertise. CETIN is leader in planning, building, operating, and maintaining networks in Serbia, securing wide availability, high reliability, security and exeptional quality.
