NTT Docomo's 5G Standalone service suffered a second nationwide outage on November 11, disrupting voice calls, data and text messages, DCD reported. The disruption ran from 10:34am to 7:17pm, following a 14-hour outage the previous Friday that affected 1.5 million customers.

Docomo blamed congestion in exchange equipment serving customers with 5G SA contracts and said its investigation found no signs of unauthorized access or cyberattacks. Standard 5G, 4G, emergency calls and virtual mobile operators using Docomo's network were unaffected.
