Telkom is Indonesia's largest telecommunications provider, delivering mobile and fixed broadband services to consumers and enterprises. The company's core operations are managed through Telkomsel, which sells prepaid and postpaid mobile data plans. Mobile data is the primary revenue driver as traditional voice and SMS services face structural decline. Telkom also provides fixed broadband via the IndiHome brand, which is integrated with Telkomsel to support fixed-mobile convergence. This integration enables Telkom to offer bundled internet, voice, and IPTV packages. The company also operates a digital infrastructure business, including tower leasing through Mitratel, satellite services, and international submarine cables managed by Telin. For corporate and government clients, Telkom provides B2B ICT solutions including cloud, cybersecurity, and managed IT services. The business model generates revenue from monthly subscriptions, data usage, recurring tower rentals, and wholesale capacity fees. Telkom’s strategy centers on expanding its data center footprint, particularly through its NeutraDC facilities in Batam, and increasing international connectivity via new subsea cable programs. The company is also implementing a portfolio simplification plan to reposition itself as a strategic holding company while deploying 5G technology in regions with high demand.
