Vodafone, which entered India in 2007 by buying Hutchison Whampoa's local cellular assets in a $11 billion deal, directly and indirectly owns a combined 84.5 percent of Vodafone India, the country's No.2 telecoms company by users and revenue.
Vodafone will buy an almost 11 percent stake in the unit from India's Piramal Enterprises, and the remainder held by investors including Indian businessman Analjit Singh, to own 100 percent of Vodafone India.
The deal was cleared by the Indian foreign investment regulator in December, but needed final approval from the cabinet.
