Application to person or A2P is a process of sending messages from an application to the mobile user. It involves automated content that an organization sends from its application to the subscriber via text message. These services can be used for various functions including alerts, confirmations, marketing campaigns, two-factor authentication(2FA), brand promotion, providing OTP, and flight alerts. The global A2P SMS market is driven by a global increase in the number of mobile subscribers, rise in cellular marketing activities by application developers and marketers, and the proliferation of A2P SMS services in mobile banking, mobile health, and mobile payments sectors.
