Network Description

Kolkata Reliance, operating within India (MCC 405) and specifically serving the Kolkata region, utilizes the Mobile Network Code (MNC) 12. As part of the Reliance Communications network, it played a significant role in connecting a vast user base across one of India's major metropolitan areas. While Reliance Communications faced financial challenges and ultimately declared bankruptcy, its legacy, including the Kolkata Reliance network, reflects a period of intense competition and innovation within the Indian telecom sector. Users in Kolkata might recall its competitive pricing and bundled data plans, which aimed to capture a substantial market share amidst the rise of other major players such as Airtel, Vodafone Idea (now Vi), and Jio.

The impact of Kolkata Reliance, identifiable by its unique MNC 12 under the Indian MCC 405, highlights the dynamic nature of the telecom landscape in Asia & Middle-East. The network, at its peak, facilitated widespread mobile communication, data access, and various value-added services for its subscribers. Understanding the history and operations of networks like Kolkata Reliance helps in appreciating the evolution of mobile technology and connectivity in India, and the factors that influenced the transition from older technologies, like 2G and 3G, towards the widespread adoption of 4G and eventual rollout of 5G networks across the nation. Its story acts as a case study for the opportunities and challenges inherent in operating a mobile network within a highly competitive and rapidly evolving market within a large and diverse country.
