Who is the ceo tata docomo?

As of my last knowledge update in October 2023, Tata Docomo is part of the Tata Group, and its operations have been integrated into Tata Teleservices. The CEO of Tata Teleservices may oversee the operations that include Tata Docomo. However, for the most current leadership information, it’s best to check the latest updates from the official Tata Teleservices website or recent news articles.
