SMS A2P
Application-to-Person SMS (A2P SMS) is a term used to describe an SMS message sent from a software application (run by an enterprise or business) to a person's phone, as opposed to P2P SMS, where communication is initiated by a person. A2P SMS is also referred to as business SMS, professional SMS, or enterprise SMS. A2P SMS allows banks to provide customers with real-time alerts for transactions and account activities. For instance, when a customer makes a large withdrawal or a significant deposit, the bank can instantly send an SMS notification.
