What is bulk SMS messaging?
Bulk SMS messaging is a legacy description for application-to-person SMS messaging services. It refers specifically to the sending of large number of SMS messages to the mobile phones of a predetermined group of recipients.
Today the application-to-person SMS messaging services have evolved to include bulk SMS messaging alongside the sending of single messages (such as one time passwords and delivery notifications), interactive messaging (such as group messaging services), and incoming number services (such as mobile marketing campaigns, voting or information lines).
A defining characteristic of bulk SMS messaging is that businesses and organisations can make use of one or more solutions to send and receive SMS messages, namely; a mobile phone application, a software programme, a web interface, or integrate an SMS API with their website or system. These bulk SMS messaging solutions interface with a service provider’s SMS gateway to ensure the delivery of messages to mobile phone numbers anywhere in the world.
An SMS gateway acts as a relay between the mobile network operators and a wireless applications service provider. These SMS gateways allow for SMS traffic to distributed via a direct connection to the SMSC (Short Message Service Centre) of a mobile network operation and then onto a recipient’s mobile phone number.
