What Is an MVNO?

An MVNO (mobile virtual network operator) sells mobile service on another operator's radio network. The host MNO carries the traffic.

MVNO in Practice

A full MVNO runs its own core network, including an HLR, and holds its own MNC. A light MVNO relies on the host MNO's core network. Numbers ported to an MVNO still ride the host's radio network. Routing depends on which core holds the subscription.
