NTT Docomo shares user data with Amazon Japan without consent

NTT Docomo: NTT Docomo is Japan's largest telecommunications company, delivering mobile, broadband, and related digital services to consumers and businesses. It recently expanded its network capabilities with deployments of advanced Open RAN equipment from partners like Nokia. In this incident, the company inadvertently shared limited customer details with Amazon Japan due to an error in consent settings for plans offering bundled Amazon Prime discounts. Amazon Japan: Amazon Japan serves as the Japanese subsidiary of Amazon, handling e-commerce operations, logistics infrastructure, and digital services tailored to the local market. It has continued expanding its physical and operational presence, including a new office in Tokyo's Azabudai Hills area. The entity received the shared user data from NTT Docomo in connection with service integrations providing Prime membership benefits to eligible mobile subscribers. Service Integration: NTT Docomo partners with Amazon to offer mobile plans that include discounts on Amazon Prime memberships, which involves data sharing for benefit verification. Data Handling Standards: Japanese companies must obtain explicit user consent before transferring personal information such as phone numbers in commercial partnerships.
