About TATA DOCOMO

TATA DOCOMO, operating in the Bihar and Jharkhand regions of India, was a notable mobile network provider identified by the Mobile Country Code (MCC) 405 and Mobile Network Code (MNC) 27. Within the broader telecommunications landscape of India, a major player in the Asia & Middle East region, TATA DOCOMO aimed to provide connectivity solutions in an intensely competitive market. While active, the network played a part in shaping the mobile communication landscape of these states, alongside other significant national operators like Airtel, Vodafone Idea (now Vi), and Reliance Jio, who have a great number of subscribers. The network's presence offered an alternative for consumers in Bihar and Jharkhand, two states with significant populations and unique connectivity needs. MCC 405 identifies India, enabling handsets and networks to correctly identify the country of origin, while the MNC code 27 specifically pinpointed TATA DOCOMO’s network infrastructure in that region. Understanding MCC and MNC codes is crucial for international roaming and ensuring proper network identification for mobile devices, the network was eventually merged with TATA Teleservices and then acquired by Airtel, contributing to consolidation trends observed within the Indian telecommunications sector.
