Indosat grows nine-month revenue 11.1 percent as ARPU rises 16.5 percent

Indosat Ooredoo Hutchison posted revenue of Rp45.75 trillion for the first nine months of 2026, up 11.1 percent year on year, with average revenue per user rising 16.5 percent to Rp46,000 and data traffic growing strongly, according to figures detailed by Bisnis.com. The customer base contracted by 3.1 million to 91.5 million subscribers over the period, a deliberate cull of low-value connections that mirrors the quality-driven approach its larger rival Telkomsel has run for years.

The combination — fewer customers, higher revenue per user and rising traffic — points to a monetization phase in the Indonesian mobile market, where operators are competing on value per connection rather than subscriber counts. For the carrier's enterprise arm, the same report notes growing demand for connectivity tied to cloud, IoT and smart-city projects, particularly in regions added to the 5G footprint this year. Management framing suggests further enterprise-focused investment as consumer growth flattens.
