"Quad Play" refers to a bundled service offering that combines four types of telecommunications services: internet, television, landline phone, and mobile phone. This package allows customers to receive all these services from a single provider, often at a discounted rate compared to purchasing each service separately. The main advantage of Quad Play is convenience, as customers can manage all their services through one account and one bill. Additionally, providers may offer enhanced features, such as integrated apps or shared data plans, making it easier for families or individuals to stay connected across multiple devices.
