How does A2P messaging work?

A2P (Application-to-Person) messaging is the process where messages are sent from an application, usually a web-based platform, to a mobile user. Messages that do not originate from a mobile device with a SIM card are regarded as A2P messages.

Popular A2P examples include critical alerts, automatic online booking confirmations, marketing efforts and real-time notifications.

As you can see in the infographic above, the process involved in sending an A2P SMS message is very similar to that of sending a person-to-person SMS message. The key difference between the two is that the SMS message is now being sent from an application rather than from a mobile phone.
