NTT Docomo

News Summary:

NTT Docomo's home 5G service recorded the highest average download speed among four major home-router services in Japan during the first half of 2026, according to an analysis of 18,243 measurements by Japanese internet services company Iid. Earlier on September 17, an analysis of Japan's mobile network performance for H1 2026 showed NTT Docomo delivered the widest 5G availability, while SoftBank led in overall connectivity and 5G speed, and Rakuten Mobile topped overall network consistency. This followed Telefônica Vivo signing a partnership deal with NTT Docomo for an Internet of Things global service. The agreement involves a global M2M inter-operator partnership to provide communication solutions for multinational companies, with a pilot scheme planned with a Japanese client in the agricultural machinery sector to remotely monitor performance and facilitate preventive maintenance. Also on September 17, NTT Docomo announced it provided personal information, including phone numbers and mobile service plans, of approximately 340,000 users to Amazon.com Inc.'s Japan unit without their consent. The company attributed this to a settings error that prevented a confirmation message from displaying during online contract signing. Previously, on September 16, Japanese telcos, including NTT Docomo, explored mmWave network sharing, acknowledging the challenge of expanding coverage due to the technology's poor propagation characteristics requiring a large number of base stations.
