How SIM-Base API Gateway Works

01

API Call Initiation

Your website and application send an API request, including message, recipient mobile number, and Sender ID to our server.

02

Authentication & Processing

Our gateway quickly verifies your credentials and DLT templates to make sure the message is secure and compliant.

03

Carrier Routing

The SMS gateway decrypts the request into a telecom-compatible format and routes it through the most reliable operator network.

04

Instant Delivery & Reporting

The message directly reaches the recipient's mobile device, and a real-time delivery report (DLR) is sent back to your system.
