OREANDA-NEWS. July 24, 2012.  NTT DOCOMO, INC., Japan’s leading mobile operator and provider of integrated services centered on mobility, announced today that subscribers to Xi™ (pronounced “crossy”), the company’s extra-high-speed LTE mobile service offering a maximum downlink of 75 Mbps, surpassed four million on July 22.

Xi reached four million subscribers just one and a half months after it surpassed the three million mark on June 8, 2012. The pace of new subscriptions nearly doubled after the introduction in summer 2012 of a Xi-compatible smartphone lineup that offered more variety to meet customer needs.

Going forward, DOCOMO expects to continue strengthening customer satisfaction with Xi-compatible smartphones, mobile Wi-Fi® routers and other devices, as well as beneficial services, such as Xi Talk 24™ for free, unlimited voice calls between DOCOMO users of Xi-compatible smartphones.
