Although in a crowded market with five major players, Vodafone is the largest British phone operator with 25 percent of the market share. Although smaller, T-Mobile UK's 15 percent market share would give Vodafone a substantial jump ahead of the rest of the pack, The Times of London reported Monday.
T-Mobile's owner Deutsche Telekom is understood to be looking for an exit from the British market, The Times said.
T-Mobile UK is said to be worth between $4 billion and $5.6 billion.
