SMS traffic can be classified as either Application-to-person (A2P) or Person-to-person (P2P).
- P2P messaging is personal messaging the end-user to end-user traffic we all use in daily life. When a person sends a text message to their family or friends using a handset or messaging app, it is a P2P message.
- A2P messaging refers to messages for business use. Most traffic sent programmatically by enterprises in large batches using webs tools or APIs integrated with their internal systems is A2P traffic.
A2P has some benefits, for example, the ability to customize routing to optimize costs and additional transparency about delivery success. At the same time, A2P is scrutinized and regulated to prevent SMS spam. A2P regulations vary from country to country and navigating the regulatory requirements of a global SMS campaign can be daunting.
