- The SMS Gateway: This crucial component acts as a bridge between the server and the cellular network. It handles the actual SMS delivery, ensuring the message reaches the recipient’s device.
- The Cellular Network: This is the final stage in the process. The SMS gateway interacts with the cellular network to send the message to the recipient.
Initiating an SMS Message
Initiating an SMS message from an Android application via a server involves several steps:
- The application sends a request to the server. This request typically includes the recipient’s phone number and the message content.
- The server validates the request, ensuring the recipient’s number is valid and the message content adheres to any specific guidelines.
- The server then forwards the validated request to the SMS gateway.
- The SMS gateway sends the message to the recipient’s cellular network.
- The cellular network delivers the message to the recipient’s device.
