A communications glitch at KDDI Corp., one of Japan’s three major mobile carriers, left countless users struggling to place calls or use the internet via their smartphones.
The problems began from around 1:35 a.m. on July 2 and still had not been fixed by 11 a.m. Company officials were frantically trying to identify the cause.
KDDI’s au and UQ Mobile services are affected as well as the “povo” plan that offers unlimited data usage.
Company officials said they were looking into how many of the 62.11 million or so of their contracted users were affected by the glitch.
Rakuten Mobile Inc., which uses KDDI’s lines, also said the same day that service in some parts of Japan were not working properly.
