T-WAN is a privately held telecommunication company based in Switzerland. T-WAN was established by a team of professionals with 60 years of aggregate and complementary expertise in the wholesale telecom sector and general IT, ranging from significant and diversified counterparties relationships to dedicated technological know-how.

T-WAN specializes in specific routes that enable it to offer both a qualitative advantage and the ability to terminate large volumes of calls, but above all, a competitive market condition worldwide.

Since January 2021, Aither Group SA has wholly-owned T-WAN. Ever since, Aither has structured and re-established T-WAN through financial and management support, granting the possibility of developing significant operational and geographical synergies.
