TOKYO, Nov. 11 (Xinhua) -- Japan's NTT Docomo Inc. said Wednesday that its 5G standalone (SA) mobile service experienced disruptions across the country, and the cause is under investigation.
According to a notice issued by the major telecommunications carrier, disruptions affecting its 5G SA service began at around 10:34 a.m. local time, and users subscribed to the service experienced difficulties using voice calls, data communications, and text messaging.
Other 5G and 4G services were unaffected, the company said.
