Videocon Mobile Service (a joint venture between Videocon and HFCL, which was renamed to Quadrant Televentures; service stopped on February 15, 2017)
MTS India, (previously Shyam Telelink) was country's only pure CDMA player. It was a joint venture between Sistema and India's Shyam Group. It was merged into RCom in October 2017 and shut down its CDMA and EVDO network in all circles.
Telenor India, formed as JV between Telenor of Norway and Unitech Group of India; later ownership went to Telenor and Telewings; ultimately Telenor acquired 100% of its Indian arm. Telenor India was acquired by Airtel by May 2018.
Aircel - It was majority owned by Maxis Communications. Aircel filed for bankruptcy in February 2018 and shut down operations immediately.
Reliance Communications, shut down its network (both 2G-GSM and 3G) 1 December 2017. They kept 4G network running only for commercial purpose. In turn Reliance Jio acquired majority of assets from RCom including spectrum.
Mobile operators 3G
MTNL was the first operator to roll out 3G services. Later BSNL, another state-owned telecom operator, also started 3G services. MTNL has wide 3G coverage over two metros, Delhi and Mumbai. BSNL has 3G coverage in all circles except Mumbai and Delhi. Currently BSNL has 3G coverage in more than 800 cities of India, and offers free roaming in Delhi and Mumbai using MTNL's network.
India completed a 3G airwave (GSM) auction for private operators and allocated 3G airwaves in September 2010 to the winners. Aircel, Airtel, Idea Cellular, Reliance (GSM), S Tel, Tata Teleservices (Tata Docomo) and Vodafone won licenses for 3G services. No operator won a pan-India 3G license.
Tata Docomo rolled out 3G services in November 2010, becoming the first private operator to roll out 3G services. Reliance Communications also rolled out 3G services in December 2010 in Delhi, Kolkata, Mumbai and Chandigarh. In Q1 of 2011 Airtel, Aircel, Idea and Vodafone rolled out their 3G services in India. S Tel has not rolled out 3G services to date.

It was expected that Infotel Broadband (majority owned by Reliance Industries) and other BWA (Broadband Wireless Access) spectrum winners will roll out LTE services in India in Q1 of 2013. However Airtel had become the first Indian operator to launch commercial LTE services in the country, starting from Kolkata.[8] However until Jio launched their beta program for LTE services in December 2015, the excitement around 4G in India was very dull.
Airtel (acquired Qualcomm, Augere, Aircel, Tikona's 4G spectrum). In May 2018 Airtel got approval from DoT to acquire Telenor India.
