KDDI and Softbank said Tuesday that they posted record high sales and operating profit in the business year through March 31 thanks to the hugely popularity of the Apple iPhone, which is continuing to contribute to their growth.
Non-iPhone provider NTT DoCoMo reported last week that its sales rose 5.4 percent to ¥4.4 trillion from the previous year, but its operating profit dropped 4.3 percent to ¥837 billion. It is the first time in six years that DoCoMo's operating profit declined from a year earlier.
The three major carriers' business results show that the iPhone remains a growth engine.
