News Summary:

On September 13, 2026, Deutsche Telekom began phasing out the Cosmote brand in Greece, moving to fully align OTE Group’s corporate identity with its global brand by introducing its magenta “T” alongside and gradually in place of the recognizable consumer brand. Previously, on September 11, the OTE Group rebranded all 111 Telekom stores across Greece, updating signage, redesigning interiors, and focusing on digital services and in-store technology experiences, including dedicated areas for mobile, fixed-line, internet fiber, television, and smart home solutions. This followed the OTE Group's announcement on September 4 that it would change its commercial brand in Greece from Cosmote Telekom to Telekom, with the transition expected to conclude by September 8. Earlier on September 3, Cosmote Telekom confirmed its transformation to Telekom as Deutsche Telekom’s Greek subsidiary adopted the group’s international brand across its products, services, and customer touchpoints. This rebranding aims to strengthen its integration with Deutsche Telekom, granting customers in Greece access to the group’s international partnerships, technology, and digital services, and allowing the brand to leverage Telekom's global strength, innovative power, and technological leadership.
