The challenge
Telecom subscribers often depend on operator-specific USSD codes for everyday actions such as checking balances, recharging accounts, activating data bundles and accessing other mobile services. These codes vary between operators and countries, making them difficult for users to remember and inconvenient to search manually.
Managing this information also becomes complicated as countries, operators, service codes and subscriber activity grow. Without a centralized system, maintaining accurate codes, linking users to the correct operator and understanding which services are used most can become fragmented and difficult to monitor.
The project required a central platform where administrators could manage telecom data while a connected mobile application could provide subscribers with the correct USSD service codes for their registered operator.
What we built
Codevioso developed a telecom-focused administration and API platform that centralizes countries, mobile operators, USSD service codes, subscriber accounts and usage analytics while providing the backend services required by a companion mobile application.
