An SMS Aggregator builds and maintains direct connections with mobile network operators (MNOs) and also indirect MNO connections via other aggregators for the delivery of A2P SMS. Any organisation wishing to send content to mobile subscribers using A2P SMS can connect with one aggregator and potentially reach hundreds of MNOs globally via this one connection.
