The British wireless provider is mulling its options for its 45 percent stake in the US's Verizon Wireless, of which Verizon Communications owns the other 55 per cent.
Analysts have suggested that Verizon wants to pay around USD 100 billion for Vodafone's stake, although reports have said that UK group is pressing for as much as USD 130 billion.
Vodafone, which has wide-ranging interests and is expanding in Europe, has long been rumored to be interested in a US exit.
