A Mobile Network Operator (MNO) is a Telecommunications Service Provider that provides wireless voice and data communications to its subscribed mobile customers. MNOs are independent Telecommunications Service Providers that own the complete telecom infrastructure for hosting and managing mobile communications.
MNO features
An important feature of an MNO is that an MNO must own or manage access to a radio spectrum license from a regulatory or government agency. A second important feature of an MNO is that it must own or manage the elements of the network infrastructure necessary to provide services to subscribers over the licensed spectrum. M2M, LTE M and NB-IOT fall under the licensed spectrum.
