SMS hubbing service enables a broad international SMS coverage for mobile network operators(MNO), virtual mobile network operators(VMNO), and other SMS service providers through a single legal, technical and billing relationship.

SMS Hubbing is about simplifying the SMS interworking system, by replacing much of the unproductive, identical investments in international agreements made traditionally by mobile operators. As well as this, SMS Hubbing is about providing a higher level of service to SMS, by introducing end-to-end quality of service through Service Level Agreements.

Every operator has the need to establish roaming agreements in order to provide subscribers with the possibility to roam outside their home network. Outside this frame of main roaming agreements that generate the majority of international traffic for messaging, it makes sense for mobile operators to allocate SMS traffic that belongs to non-connected destinations to an SMS hub.

With the SMS Hubbing model, an operator looking to increase their international SMS coverage does not need to manage multiple bi-lateral agreements. Mobile operators can simplify this by connecting to a hub. The SMS Hubbing model reduces complexity for operators, as well the cost for SMS interworking agreements. Mobile subscribers also take advantage of an enlarged SMS reach, being able to send and receive message to all countries and networks.
