Hello? Listening in on India’s Telecommunications
India maintains its position as the second-largest telecommunications market in the world by subscriber count, acting as a foundational backbone for the nation’s digital economy.
Telecommunications in India is comprised of three main categories: mobile (wireless), fixed-line (wireline), and Internet services.
Mobile and fixed-line telecommunication allows direct communication through the operation of switching and transmission facilities. Mobile telecom companies use air waves while fixed-line telecom requires twisted pair cables. Both use optical fiber cables, microwave radios and/or satellite link-ups for backhaul and backbone purposes. 97% of subscribers in India use wireless services; the remainder utilize wireline.
For Internet services, consumer and corporate channels use Internet Service Providers (ISPs). There are over 1 billion Internet subscribers in India as of 2026.
Telecom Circles/Service Areas
There are 22 telecom service areas (telecom circles) in India that are separated into four categories covering different areas:
- Metro – major cities such as Delhi, Mumbai, and Kolkata
- “A” category circles are the ones with highest telecom subscriber counts and include states such as Andhra Pradesh, Gujarat, Karnataka, Maharashtra, and Tamil Nadu
- “B” category circles are the ones with medium telecom subscriber counts and include states such as Haryana, Kerala, Madhya Pradesh, Punjab, Rajasthan, Uttar Pradesh, and West Bengal
- “C” category circles are the ones with relatively low telecom subscriber counts and include states such as Assam, Bihar, Himachal Pradesh, Jammu and Kashmir, Orissa, and the seven northeastern states of India.
Telecom service providers that want to operate in India must obtain a license for the desired circle. India’s Department of Telecommunications holds auctions to distribute electromagnetic spectrum licenses and has recently completed auctions for 3G spectrum.
