IMEI NOTE: A four-carrier phone checker

Why it surfaced

This is unusually concrete utility: it supports single lookups, batches of up to 100 IMEIs, CSV input, clipboard capture, and reading IMEIs from up to five screenshots in the browser. It also clearly labels itself as an independent, non-official service and explains what its symbols cannot prove.

A Japanese tool that checks a phone’s 15-digit IMEI against network-use restriction data from docomo, au, SoftBank, and Rakuten Mobile.
