What is A2P SMS?


SMS is an acronym for Short Message Service, also commonly known as a text message. SMS messages are messages of up to 160 characters in length sent via smartphones, feature phones or tablets.

SMS has been around for over 25 years, used massively by people to communicate easily with family and friends. As with many technology services that have started with a consumer approach, SMS is now invaluable for businesses, allowing them to communicate with customers, employees, and other stakeholders worldwide. This evolution of text messaging is known as application-to-person (A2P) SMS and is being used in a wide range of use cases: customer service, two-factor authentication, mobile marketing and more.
