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) WCDMA, 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 Share repurchase 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
NTT Docomo had over 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 Mobile. 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 July 2012, NTT Docomo acquired Italy's Buongiorno in a deal worth 209 million euros.

Investments outside Japan
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
, 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.
In December 2007, NTT Docomo and KTF jointly invested US$200 million for a total of 33% stake in U Mobile Malaysia.
In June 2008 NTT Docomo joined the non-profit Symbian Foundation led by Nokia to co-develop a new Symbian smartphone operating system based on the S60 platform, which resulted in Symbian^2 for the Japanese market.
In November 2008, NTT Docomo bought a 26% stake in Tata Teleservices for US$2.7 billion, the number 6 in Indian telecom industry and owned by the Tata group. India is the world's fastest-growing cellular market, adding as many as 9 million new customers a month. Tata Teleservices (which sells under the brand Tata Indicom and Virgin Mobile India) has 80 million subscribers as of October 2010. Though Tata Indicom is a CDMA based operator, they won GSM licenses as well, and the NTT Docomo-Tata venture is focused on GSM operation (called Tata Docomo). The Tata Docomo service was commercially launched in India in June 2009. Tata Docomo had about 32.82 million users at the end of June 2010. NTT Docomo was in litigation with Tata Sons over repatriation of money while selling the entire stake of tata teleservices back to tata sons.
