Boosted by the soaring number of mobile phone users, cellular operator NTT DoCoMo Inc. announced Wednesday that it posted consolidated sales of 3.72 trillion yen for fiscal 1999, which ended in March, up 19.3 percent from the previous year.

The cellular giant also saw an increase in its already huge profits. The company's operating profits came to 545.76 billion yen, up 7.3 percent, its pretax profits stood at 503.12 billion yen, up 43.6 percent and net profits totaled 252.14 billion yen, up 23.1 percent.

In particular, NTT DoCoMo President Keiji Tachikawa attributed the firm's strong performance to the popularity of its i-mode service, an Internet-browsing service offered on DoCoMo's smart mobile phones.
