Airtel won 3G licences in 13 telecom circles of India: Delhi, Mumbai, Andhra Pradesh, Karnataka, Tamil Nadu, Uttar Pradesh (West), Rajasthan, West Bengal, Himachal Pradesh, Bihar, Assam, North East, and Jammu & Kashmir. Airtel also operates 3G services in Maharashtra & Goa, Kolkata, Gujarat and Punjab circles through an agreement with Vodafone Idea. This gives Airtel a 3G presence in all 22 out of 22 circles in India. Airtel is fined by DoT 3.50 billion for not stopping offering 3G Services through Roaming Pacts outside its Licensed Zones in Seven Circles.
On 20 September 2010, Bharti Airtel said that it had given contracts to Ericsson India, Nokia Siemens Networks (NSN) and Huawei Technologies to set up infrastructure for providing 3G services in the country. These vendors would plan, design, deploy and maintain 3G–HSPA (third-generation, high-speed packet access) networks in 13 telecom circles where the company had won 3G licences. While Airtel awarded network contracts for seven 3G circles to Ericsson India, NSN would manage networks in three circles. Chinese telecom equipment vendor Huawei Technologies was introduced as the third partner for three circles.

In 2019, Airtel shut down their 3G network in Kolkata. In Kolkata users can only access 4G and 2G networks.

Airtel obtained 4G licences and spectrum in the telecom circles of Delhi, Haryana, Kerala and Mumbai after acquiring Wireless Business Services Private Limited, a joint venture founded by Qualcomm, which had won BWA spectrum in those circles in the 4G spectrum auction.

On 30 November 2015, Airtel announced the launch of a network transformation programme called Project Leap. Under the programme, the company will invest ₹60,000 crores over the next 3 years to upgrade its network across India. Airtel will deploy over 160,000 base stations nationwide, and also expand its mobile broadband coverage to over 500,000 villages. Under Project Leap, Airtel will introduce several technologies such as small cells, carrier aggregation solutions, WiFi hotspots, and several different spectrum bands to improve network coverage in indoor areas. The company will also deploy more than 5,50,000 km of domestic and international fibre, and upgrade its legacy networks and base stations over the three-year period.
Airtel Broadband will also benefit from Project Leap. The ISP's maximum offered speed will rise from 16 Mbit/s in 2016 to 50 Mbit/s when after the programme is implemented.
On 14 June 2016, Airtel launched the Open Network initiative under Project Leap.

Net Neutrality Debate
In April 2015, Airtel launched a marketing platform called Airtel Zero, which allows application providers to pay for the data used by the consumers, enabling consumers to access specific mobile apps at zero data cost. Flipkart, a leading Indian e-commerce firm reportedly was to become the launch partner of "Airtel Zero". The issue triggered debate on net neutrality in India and following protests Flipkart pulled out of Airtel Zero.
