SMS hubbing is a new structure for the international flow of SMS between operators, reshaping the way that international mobile inter-operability works by implementing hubs to intermediate the SMS traffic and to offer a larger SMS coverage.

Regardless of the maturity of the operator or number of subscribers, each subscriber expects to be able to send an SMS to other subscribers, regardless of country and mobile network.

With the CS Networks 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.
