Project Title: SIM-Based Auto-Calling Mobile Application with Voice Broadcast Feature

Issued By:

Tinplate Computer Training Center

1. Project Overview

Tinplate Computer Training Center invites proposals for the design and development of a SIM-Based Auto-Calling Mobile Application with Voice Broadcast Feature. This project aims to automate outbound calling operations and enable bulk voice messaging using SIM-based mobile communication, without relying on internet-based calling.

The application will be used for marketing, notifications, reminders, training calls, and information broadcasting. The system should work using the mobile device’s SIM card and function as a smart, automated dialer with integrated voice broadcast capabilities.
