Similarly, banks can automatically send OTP verification codes, while hospitals can send appointment reminders without any manual effort.

How SMS Gateway Solutions Work
Understanding the technology behind SMS Gateway Solutions is surprisingly simple.
A customer completes an action such as registering on a website, placing an order, booking an appointment, requesting an OTP, or completing a payment. The business application generates an SMS automatically.
The application connects with the SMS Gateway API. The API securely transfers the message details to the gateway server.
The gateway verifies the Sender ID, recipient number, message content, delivery route, and network availability.
The gateway forwards the message to the appropriate mobile operator. The operator delivers the SMS directly to the recipient's mobile phone.
Businesses receive delivery reports that indicate whether the message was delivered, pending, failed, or expired. This provides complete visibility into communication performance.
