What Is A2P SMS and How It Differs from P2P Messaging
Application-to-Person messaging or A2P SMS implies transferring of text messages from an application or software to an individual. It enables delivery of transactional alerts, marketing messages, authentication codes, and notifications.
What Is the Flow with A2P SMS?
A2P messaging entails three basic elements in its ecosystem: a sender, a messaging service provider or MSP, and a recipient. A sender can be an application or software that launches the message. The recipient is the one who receives the message on the particular device. A messaging service provider is a bridge between the two that simplifies sending messages from the sender to recipient. The overall flow is as follows:
The process of A2P messaging begins with the app generation of the message.
The message is then transmitted to the MSP through the API or another channel of communication.
The MSP receives and verifies the message, aligning it with the local regulations and guidelines.
After that the MSP routes the message to the necessary mobile network operator or aggregator, which sends the message to the device.
How Does A2P Operate?
A2P messaging operates on several technologies and protocols. First of all, it comes to utilizing Short Message Peer-to-Peer (SMPP), which is a protocol developed for high-volume messaging. SMPP enables efficient and reliable communication between the sender, MSP, and MNO. Another technology involves using application-specific APIs provided by MSPs, which provides integration of messaging capabilities into the existing applications or software.
