SMS Gateway
An SMS Gateway is a telecommunications platform that enables applications to send and receive SMS (Short Message Service) messages programmatically, typically via APIs. It acts as an intermediary between software systems and mobile network operators, handling message routing, delivery, and often features like two-way communication, bulk messaging, and international support. This technology is essential for automating SMS-based notifications, alerts, marketing campaigns, and authentication workflows.
Developers should learn and use SMS Gateways when building applications that require reliable SMS communication, such as sending OTPs (One-Time Passwords) for user authentication, transactional alerts (e.g., order confirmations), or marketing messages to customers. It's particularly valuable in industries like e-commerce, finance, healthcare, and logistics, where timely and secure text-based notifications are critical for user engagement and operational efficiency.
