SMS Gateway
An SMS Gateway is a technology platform that enables applications to send and receive SMS (Short Message Service) messages programmatically, typically by connecting to mobile network operators or aggregators. It acts as an intermediary that translates API requests into SMS protocols like SMPP or HTTP, allowing integration with software systems for automated messaging. Common uses include notifications, alerts, two-factor authentication, and marketing campaigns.
Developers should learn about SMS Gateways when building applications that require reliable, scalable SMS communication, such as for user authentication (2FA), transactional alerts, or customer engagement in e-commerce, banking, or healthcare. It's essential for projects needing global reach, as gateways often provide connectivity to multiple carriers and handle complexities like delivery reports and compliance with regulations like GDPR or TCPA.
