Looking for mobile balance transfer study materials

Question

I need to make a web application for mobile phones so that I can transfer balance from a 'recharge sim' (SIM card used to send balance to other mobile SIMs) located in whatever country to other 'non-recharge sims'.

I can't find any resource - documentation, tutorial, forum discussion, programming language etc.

Where should I start? What materials, etc, are out there? Is there any open-source project I could refer to?
