The challenge
USSD powers Mobile Money for hundreds of millions on feature phones, but designing and testing those menu flows usually needs a real SIM, a gateway and a device.
Our approach
- Recreated a realistic handset dialer and USSD session experience
- Made request/response flows fully configurable for any service
- Built it browser-based so teams can prototype instantly
- Kept the UI true to a real feature-phone interaction
The solution
A configurable USSD simulator that lets teams prototype and demo Mobile Money menu journeys in the browser — closing the loop between design and the realities of feature-phone users.
