SIM Activation Tracker App Development

I'm seeking a developer to create a robust application for both mobile and computer platforms (specifically Windows and Android). This application will allow me to input a list of phone numbers and retrieve their SIM activation dates, sorted by date and carrier name, and ideally, the exact time of activation. Key Features: - Fast processing to accommodate a large number of entries. - A filter option to locate numbers activated on a specific date. - The capability to track call history for any Indian number. The application needs to be user-friendly, efficient, and tailored to operate within India's telecommunication framework. The input of the number lists will be done manually. Ideal Skills: - Expertise in cross-platform application development. - Strong knowledge of telecommunication data retrieval and sorting. - Experience with Windows and Android systems. - Ability to design a simple yet efficient user interface. This project requires someone who can deliver a high-performing application that meets these specific requirements.
