MNO
Mobile network operator: the company that holds spectrum licenses and runs the radio access and core network that carry traffic.
Definitions only — a term explained here is not a service we sell.
A mobile network operator (MNO) holds the spectrum license and runs the radio access and core. Virtual operators and brands buy wholesale access; selling SIMs does not make a brand an MNO.
Radio and core can come from different suppliers, and parts can be shared. The license defines an MNO, not ownership of every element. Numbering and interconnection agreements sit with the operator.
Who controls the route
Wholesale SMS and data reach the MNO through aggregators and roaming hubs. The terminating network controls the sender rules and delivery receipts. A direct route should connect to the MNO or its official wholesale arm: ask for the path, not the adjective. For data devices, the Cellular bearers compared explainer sets out the radio options.

Text description
The blocks run from spectrum to brand in five steps: spectrum, the MNO, the mobile core, an MVNO platform and a brand. The MNO holds the spectrum license and runs the core; the platform and brand buy wholesale access from the operator.
