Docomo’s nationwide 5G SA disruption

  1. Update 1 of 1LatestDay 7

    Docomo’s nationwide 5G SA disruption nears three hours, with no recovery estimate

    Calls, data and SMS remained unreliable for standalone 5G subscribers at 1:30 p.m. JST. Emergency calls were unaffected, and switching to 4G may help.

    What we knew first

    • A Docomo phone could display “no service,” yet emergency calling was unaffected. That was one important distinction in a disruption that reached across Japan on November 11, 2026: ordinary calls, mobile internet and SMS were difficult to use for subscribers to the carrier’s standalone 5G option, but the problem did not extend to every Docomo customer.
