Turk Telekom Online Services App
Turk Telekom Online Services mobile app was a critical platform with frequent errors in its previous stack. Users could not move smoothly through home internet, mobile line and fixed-line operations, and repeated failure scenarios appeared in billing and service flows. We redesigned the entire product for iOS and Android from the ground up. While rebuilding the screens, we also modernized the backend services, data flow and transaction logic. The result was a reliable digital channel for self-service operations. This transformation delivered an infrastructure improvement that directly affected customer satisfaction and call center load.
Project overview
Problem: The Turk Telekom Online Services mobile app was a critical platform that frequently failed in its previous stack. Although users could access home internet, mobile line and fixed-line services, the experience was not truly smooth and recurring error scenarios appeared in billing and operational flows.
Solution: We redesigned the product from the ground up for iOS and Android. While rebuilding the screens, we modernized not only the interface but also the backend services, data flow and transaction logic. Home internet management, mobile line operations, fixed-line services and billing flows were brought together in one consistent experience. Error handling and feedback mechanisms were strengthened so users could complete tasks in a safer and more understandable way.
Result: The app was relaunched as a seamless digital experience across Turk Telekom's channels. As a result, operations became easier to manage, user experience improved and customer service load decreased. This case study shows how a critical mobile platform can become a reliable, scalable and brand-supporting product when the right technical architecture and UX approach are applied.
