This document outlines a proposed prepaid wireless service product. It describes key benefits for customers including convenience, control over expenses without lengthy contracts, and flexibility. The product lifecycle includes buying airtime cards with talktime balances and validity periods, recharging balances as needed, and cards expiring if not recharged in time. Various price plans would be available, but the core milestones like talktime validity would remain the same. Business rules would define pricing, airtime durations and expirations, card expirations, and number recycling policies. The goal is to give customers easy, flexible mobile access without long-term commitments.
