Vodafone India is one of the largest mobile operators in India, with over 134 million customers as of 2011. While India makes up 36% of Vodafone's global customer base, it contributes only 8% to revenue due to intense price competition in the Indian mobile market. Vodafone Essar (now known as Vodafone India) operates in 23 of India's telecom circles through a joint venture between Vodafone Group (67% stake) and Essar Group (33% stake). It has emerged as one of the major players in India's highly competitive telecom sector.
