NTT DOCOMO passed the 15 million subscriber milestone for its Xi LTE service on July 30.
DOCOMO first launched its commercial LTE service on December 24, 2010. Subscribers reached one million in December 2011, 10 million in February this year and now, just five months later, 15 million. The company said growth had accelerated thanks to successful promotions for its new summer lineup, including special discounts introduced in May for the extra-popular Xperia A SO-04E and GALAXY S4 SC-04E models.

In July, NTT DOCOMO announced plans to push its LTE service to 150 Mbps maximum downlink rates, roughly double today's top performance. The 150 Mbps service is currently being verified in Kawasaki, Kanagawa Prefecture.
NTT DOCOMO expects to launch 150 Mbps commercial service this October, starting in parts of Tokyo, Osaka and Nagoya.
DOCOMO, in addition to steadily improving the quality of its LTE network for increased reliability, continues to upgrade LTE coverage and data transmission speeds, most recently by expanding 112.5 Mbps downlink service to more than 130 cities as of July 2013.
