Number overview
0120-967-328 appears in the official NTT Docomo FAQ listing the legitimate caller numbers of the NTT Docomo Consulting Center. We confirmed the listing on the official FAQ (as of 2026-08-03). Docomo explains that these numbers are used to propose smartphone upgrades and services such as Docomo Hikari.
This site previously described the number as a nuisance call using a fictitious organization name. Re-verification against the official FAQ confirmed the Docomo attribution, so we corrected the page.
