NTT Docomo Inc.is the predominant mobile phone operator in Japan. The name is officially an abbreviation of the phrase, "do communications over the mobile network", and is also from a compound word dokomo, meaning "everywhere" in Japanese. Docomo provides phone, video phone (FOMA and Some PHS), i-mode (internet), and mail (i-mode mail, Short Mail, and SMS) services. The company's headquarters are in the Sanno Park Tower, Nagatachō, Chiyoda, Tokyo.
Docomo had been spun off from Nippon Telegraph and Telephone (NTT) in August 1991 to take over the mobile cellular operations, although the parent company had the majority stake until the re-privatization in 2020. It provides 2G (mova) PDC cellular services, 3G (FOMA) W-CDMA, 4G LTE and 5G NR services. Its businesses also included PHS (Paldio), paging, and satellite. Docomo ceased offering a PHS service on January 7, 2008. In late 2020, Docomo was privatized by NTT for about $40 billion.
NTT Docomo is a subsidiary of Japan's incumbent telephone operator, NTT. The majority of NTT Docomo's shares are owned by NTT (which is 33.71% government-owned). While some NTT shares are publicly traded, control of the company by Japanese interests (government and civilian) is guaranteed by the number of shares available to buyers. It provides wireless voice and data communications to subscribers in Japan. NTT Docomo is the creator of W-CDMA technology as well as mobile i-mode service.
NTT Docomo has more than 53 million customers (as of March 2008), which is more than half of Japan's cellular market. The company provides a wide variety of mobile multimedia services. These include i-mode which provides e-mail and internet access to over 50 million subscribers, FOMA, which was launched in 2001 as the world's first 3G mobile service based on W-CDMA, Xi, a 4G LTE mobile service which was launched on December 24, 2010, Premium 4G, a LTE Advanced service which was launched on March 27, 2015, and DoCoMo 5G, a 5G NR service which launched on March 25, 2020.
In addition to wholly owned subsidiaries in Europe and North America, the company is expanding its global reach through strategic alliances with mobile and multimedia service providers in Asia-Pacific and Europe. NTT Docomo is listed on the Tokyo (9437), London (NDCM), and New York (DCM) stock exchanges.
On April 19, 2008, it was announced that Ryuji Yamada, the current co-president of NTT Docomo, will be promoted as the president of NTT Docomo in June 2008. Masao Nakamura will stay in NTT Docomo as a director and also the senior adviser. Since October 2006, when the introduction to the service which allows the user to carry their original phone number with a new provider was made, NTT Docomo has lost many users to KDDI and SoftBank. This promotion was made in order to get more users for NTT Docomo.The company was the last major global mobile carrier to offer Apple's iPhone, which it finally did with the release of the iPhone 5s and 5c. This has been cited as one of the reasons for the steady stream of its customers switching for competing networks.
In June 2011, the company announced that they were teaming up with McAfee to provide McAfee VirusScan Mobile for its Android mobile users.In July 2012, NTT Docomo acquired Italy's Buongiorno in a deal worth 209 million euros.

These alerts have a unique ring tone so they can be easily distinguished from incoming calls or messages.

The first set of 176 12×12 pixel emoji was created as part of i-mode's messaging features to help facilitate electronic communication, and to serve as a distinguishing feature from other services.
NTT Docomo has a wide range of foreign investments. However, NTT Docomo was not successful in investing in foreign carriers. Docomo had invested very large multibillion-dollar amounts in KPN, KT Freetel, AT&T Wireless, and had to write-off sell all these investments in foreign carriers. As a result, Docomo booked a total of about US$10 billion in losses, while during the same time Docomo's Japan operations were profitable.

Symbian was originally developed as a proprietary software OS for PDAs in 1998 by the Symbian Ltd. consortium. Symbian OS is a descendant of Psion's EPOC, and was released exclusively on ARM processors, although an unreleased x86 port existed. Symbian was used by many major mobile phone brands, like Samsung, Motorola, Sony Ericsson, and above all by Nokia. It was also prevalent in Japan by brands including Fujitsu, Sharp and Mitsubishi. As a pioneer that established the smartphone industry, it was the most popular smartphone OS on a worldwide average until the end of 2010—at a time when smartphones were in limited use—when it was overtaken by iOS and Android. It was notably not as popular in North America.
