A mobile network operator (MNO), is also known as a wireless service provider, wireless carrier, cellular company, or mobile network carrier.

A mobile network provider is a wireless communications service provider that owns or controls all of the elements required to sell and deliver services to end users, including radio spectrum allocation, wireless network infrastructure, back haul infrastructure, billing, customer care, provisioning computer systems, and marketing and repair organizations.

An MNO may provide network access to mobile virtual network operators at wholesale prices in addition to generating money by selling retail services under its brand (MVNO).
