A telephone subscriber refers to an individual, household, or business that has been registered with a telecom service provider to access telephone services, either through mobile (wireless) connections or fixed-line (wireline) connections. It essentially represents the number of active users who can make and receive calls, and often also access data services, depending on the type of subscription. Tracking the number of telephone subscribers is highly relevant as it serves as a key indicator of telecommunication penetration, accessibility, and digital connectivity within a country or region. It helps policymakers, regulators, and businesses understand the extent of communication infrastructure, the level of adoption of modern technologies, and the inclusiveness of digital growth. A rising number of subscribers generally signals greater connectivity, enhanced access to information, and improved opportunities for economic and social participation, whereas stagnation or decline may point to challenges such as affordability, infrastructure gaps, or shifts to alternative technologies. Therefore, monitoring this indicator is crucial for assessing progress in bridging the digital divide and for planning future investments in telecom and digital services.
