PremiumSub
Data, airtime, VTU, and utility payments — web and mobile
PremiumSub is a VTU and utility payment platform for purchasing mobile data bundles, VTU airtime, electricity bills, and TV subscriptions (DStv, GOtv, Startimes). ScalerDev built the web platform and mobile apps — available on Google Play and the App Store — with API integration for resellers and affiliated websites.
Business objective
Deliver a full VTU product — marketing website, user dashboard, mobile apps, and developer API — so resellers and end users can buy data, airtime, cable, electricity, and related services from one platform.
The problem
VTU businesses need more than a basic recharge form — they need a trustworthy web presence, mobile apps for on-the-go purchases, reseller API access, and support for advanced services like recharge card printing and airtime-to-cash.
Our solution
ScalerDev built PremiumSub as a complete VTU platform — professional web homepage with register/login, mobile apps for Android and iOS, service flows for data, airtime, cable, and electricity, plus API documentation for integrating with external websites.
