NTT DoCoMo's net income falls 21% in Q2

NTT DoCoMo said its first-quarter net income fell 21 percent as it spent money to prepare for the onslaught of local number portability some time in October. DoCoMo is widely believed to be most at risk of losing customers because it has the vast majority at 52 million. To better its market position, it significantly increased spending on marketing and improving the network. DoCoMo said Friday that the rise in costs contributed a decline in group net profit for the quarter, to $1.42 billion from $1.81 billion a year earlier.
