Chapter 01— Overview
Revitalizing online product discovery for 170+ million subscribers.
Telkomsel is Indonesia’s flagship telecommunications giant. Working alongside the Web & E-Commerce (WEC) division, my focus was rethinking how millions of customers discover, configure, and purchase data plans, roaming passes, eSIMs, and lifestyle bundles through Telkomsel's web storefront.
The challenge was making an enormous catalog feel lightweight, transparent, and frictionless to buy.
Chapter 02— The Challenge
Streamlining hundreds of complex telecom SKUs into clear buying journeys.
The existing web store had accumulated hundreds of promotional packages, confusing quota splits (local, national, app-specific), and friction-heavy payment steps that caused high cart drop-offs.
We needed to give users total transparency over quota validity while providing internal marketing teams with a modular, drag-and-drop CMS to spin up promotional campaigns without touching code.
“When buyers clearly understand what data they are purchasing and why, hesitation disappears and conversion follows naturally.”
