In 2007 it acquired 100% of Attica Telecom,[4] the largest provider of fiber-optic services in the city of Athens and in June of the same year established a strategic partnership with Vodafone Greece.

Hellas Online owns and operates a fibre optic network of approximately 3,500 kilometres (November, 2008).

Through its points of presence (PoPs) consisting of physical co-location in unbundled local loops (LLUs) Hellas Online offers extensive population coverage in the metropolitan areas of the two largest cities in Greece, Athens (over 80%) and Thessaloniki (over 70%), and significant population coverage in the rest of Greece.

Hellas Online's extensive proprietary fibre optic network connects the three major Greek cities of Athens, Thessaloniki, and Patras, and covers significant parts of the most densely populated areas of Greece.

In 2009, Hellas launched an IPTV service, featuring access to free-to-air channels, news, information, music, children's and sports drawn from around the world and HD content.
