According to news on October 16th, according to the Nikkei Chinese website, NTT docomo, the largest telecommunications operator in Japan, had a nationwide network failure from 5 pm to 8 pm local time on the 14th. Almost all mobile phone users across the country cannot receive the signal. Since then, the company announced that 5G and 4G networks have been repaired, but some of the 3G lines used by "feature phones" are still difficult to connect. According to the official, it is impossible to predict when it will be completely repaired.

Docomo claimed that the service began to resume at 8 pm, but as of 11 pm local time, a large number of users still reported connection problems. The company held an online press conference at 2 pm on the 15th. Vice President Hozumi Tamura apologized, saying, “We apologize for causing trouble and worry to everyone. We will work hard to find out the cause and prevent the incident from happening again. "

 

It is worth noting that some users reported on Twitter that mobile phones using docomo's low-cost operator ahamo's eSIM service can receive signals and surf the Internet, but cannot make calls.

As of press time, the status page of NTT docomo's official website shows that communications in various parts of Japan have returned to normal.
