A mobile network operator or MNO recognized also as a wireless service provider, wireless carrier, cellular company, or mobile network carrier, is a provider of wireless communications services that owns or controls all the elements necessary to deliver services to end-users, including radio spectrum allocation, wireless network infrastructure, and other necessary components.
Mobile network operators use a network of cell towers to deliver services. These towers are connected to a mobile network backbone, which is connected to the public telephone network.
This allows users to make and receive calls, send and receive text messages, and access the Internet. Mobile network operators also have their own billing systems that provide users with monthly statements.
Additionally, mobile network operators provide customer care services to help users with any issues they may have.
Some popular examples of mobile network operators include AT&T, Verizon, T-Mobile, Sprint, and Vodafone.
