Case Study: Kyivstar Drives Mobile Revenue and User Retention with OneSignal

Kyivstar Uses OneSignal to Boost MAU and LTV

Kyivstar, Ukraine’s largest telecommunications network, needed a more effective way to engage users of its My Kyivstar mobile app and overcome limitations in its previous messaging tool. The company wanted better targeting, automation, and reliability to support retention, feature adoption, and revenue growth. Kyivstar chose OneSignal, using its mobile push notifications, in-app messaging, Journeys, and Amplitude integration to improve precision and speed.

With OneSignal, Kyivstar built dynamic real-time segments, automated messages around billing and account events, and created in-app education flows for new features and product changes. The results included a 10% increase in monthly active users, a 50% increase in revenue-generating transactions, up to 10 million UAH in incremental monthly growth from top-up notifications, and a 10% lift in overall mobile communication service revenue.
