What is an SMS gateway for two way messaging
An SMS gateway serves as the crucial bridge between web applications, software platforms, and mobile networks—enabling businesses to send and receive SMS messages programmatically. Unlike basic SMS solutions that focus solely on outbound messaging, a two way SMS gateway enables both sending and receiving text messages at scale, fostering real-time interactions with customers, clients, or team members.
