Yettel Hungary, a major enterprise telco provider and a long-term strategic partner, relies on its self-service mobile app as its primary customer channel. We have been instrumental in its development and maintenance, ensuring it meets evolving user expectations.

Recently, Yettel introduced Yepp, a fully digital mobile plan with unlimited data and seamless onboarding. This was not just a new product launch but a comprehensive digital transformation project as well. Our challenge was to integrate its advanced functionalities—such as digital contract management and eSIM activation—while maintaining high system stability, exceptional code quality, and a continuously evolving feature set.
