Telecom sector in India is already filled with lots of players, like airtel, vodafone, idea etc...
Its not easy for any foreign player to break into Indian mkt straight away, as competition is already taken up... on top of that, India's tax policies, and d not-so-ease of doing business regimes, makes it difficult for any new entrant.
Earlier this hppnd with ORANGE as well, orange hutch company... they were forced to leave India mkt, bcoz of low profits..
