DOCOMO

Kolkata, a vibrant metropolis in India, and the cultural capital of the country, was at one point served by TATA DOCOMO, a mobile network operating under the MCC (Mobile Country Code) 405, which identifies India, and MNC (Mobile Network Code) 36. TATA DOCOMO, a GSM network, aimed at providing comprehensive mobile services across various circles in India, including voice and data. While no longer operating under that name, the legacy of TATA DOCOMO remains a relevant part of India's telecom history, reflecting the competitive landscape and the evolution of mobile communication technologies in the region. TATA DOCOMO, while present in Kolkata, as well as the wider West Bengal circle, competed with other major players like Airtel, Vodafone (now Vi), and Reliance Jio. The entry of networks like Reliance Jio with disruptive pricing strategies has significantly altered the Indian telecom sector, leading to consolidation and acquisitions. TATA DOCOMO ultimately merged with TATA Teleservices and later sold to Bharti Airtel. A key detail for mobile network enthusiasts and those needing specific network information is its MCC of 405 and MNC of 36, codes once crucial for identifying the network's presence on mobile devices and network configurations. It should be noted that users may now see their SIMs registered as Airtel with the same ID or migrated.
