The Problem

Millions of prepaid customers still visit physical dealers each month to keep service active. PayCellBill wanted to streamline that experience with a secure, mobile-first alternative.

Key Requirements

  • Ensure PCI-compliant payments and data handling within a mobile app experience.
  • Support multiple carriers and adjust to varying account identifiers.
  • Keep the experience fast and intuitive so users complete payments in under a minute.

  • App store reviews averaged 4.6 stars, citing convenience and reliability.
