This series provides a weekly roundup of developments in low-cost SIMs, SIM-free smartphones, and more, complete with price lists for major MVNOs. Last week's highlight was the 'My docomo' issue, which also impacts ahamo users. While some procedures, whose safety has been confirmed, have resumed, several remain unavailable as of the time of writing.
Emergency Maintenance Following Unauthorized Access to My docomo: Many Procedures Now Available, But Some Remain Suspended
On Wednesday, November 4, unauthorized access to the Docomo Online Shop and My docomo occurred, leading to the leakage of some user information. A maximum of approximately 300,000 pieces of data were compromised. Immediately following the incident, both the Docomo Online Shop and My docomo entered emergency maintenance. However, some procedures have been progressively resuming since Friday, November 9.
Conversely, the procedures that are still unavailable are listed below. Notably, 'Plan changes from ahamo' and 'JAL Mobile Option application/cancellation' are particularly problematic due to their direct relevance to ahamo users. The ahamo website itself was also temporarily suspended but has since resumed operation, with no confirmed information leakage from that platform.
