From push-button phones to global 5G: The rise of India's telecom giant
In short: Bharti Airtel began by replacing bulky rotary phones with push-button devices in 1984. Today, it is the second-largest mobile network operator in the world, spanning 18 countries. From its humble origins in New Delhi to pioneering 5G and satellite internet, Airtel has reshaped how millions connect across continents.
The company's trajectory started when Sunil Mittal began importing push-button phones from Singaporean firm Singtel, eventually forming Bharti Telecom Limited to manufacture them locally with Germany's Siemens AG. By 1992, Mittal secured a mobile network license for Delhi, launching services in 1995 under the brand name AirTel. This early move into mobile telephony proved prescient, as the company quickly became the first in India to surpass 2 million mobile subscribers.
Expansion was fueled by strategic acquisitions and infrastructure investments. In 2010, Bharti completed its largest acquisition to date, purchasing the African operations of Zain Telecom for $10.7 billion, which propelled it to become the world's fifth-largest wireless carrier at the time. The company has consistently sought to consolidate its market position, acquiring assets from Telenor India, Tikona Infinet, and the consumer mobile business of Tata Teleservices, while also expanding into digital services like Airtel Payments Bank and cloud solutions with Google Cloud.
Technological evolution remains central to Airtel's strategy. Having moved beyond basic voice services, the firm now deploys 5G, 4G, and LTE Advanced technologies. Recent milestones include successful 5G Cloud-RAN trials with Nokia and a multi-billion dollar deal with Ericsson to upgrade network infrastructure. Looking ahead, Airtel is exploring satellite-based internet through a strategic agreement with SpaceX's Starlink, signaling its intent to maintain connectivity leadership as digital demands grow.
Today, Bharti Airtel operates as a multinational entity with a complex ownership structure, where Bharti Telecom acts as a holding company backed by Bharti Enterprises and Singtel. While it faces intense competition, particularly from Reliance Jio in the Indian market, its diversified portfolio—ranging from enterprise connectivity to digital television and broadband—underscores its role as a foundational pillar of modern telecommunications infrastructure.
