The device blocked the ring, flagged it as spam, and O2 sent a missed‑call alert. Apart from the site labeling it as Three Mobile, I have no clue who it was.

专家点评
A mysterious ring from an unfamiliar line gets flagged as spam before it even buzzes, with O2 chiming in about a missed call and online hints pointing to Three Mobile. Such automated blocks are a handy shield against nuisances, but it's wise to stay cautious—unknown callers like this could be anything from misdialled mobiles to dodgy schemes. Double-check your network settings for spam filters, and if texts or voicemails follow, verify directly with your provider rather than replying. Keep a log of these incidents to spot patterns, and consider apps that whitelist trusted contacts only. In the end, when in doubt, hang up and investigate properly to avoid any potential pitfalls.
