What is an MVNO?

MVNO stands for Mobile Virtual Network Operator.

They are basically like virtual telcos that do not own the infrastructures that they use to provide services. Instead, they can rent infrastructure from existing established telcos or Mobile Network Operators.

MVNOs can afford to keep the prices of their SIM Only plans so attractively low because they do not have to maintain their own infrastructure, neither do they have much brick-and-mortar presence.
