T-Mobile has now launched Caller Verified technology, which uses the STIR and SHAKEN standards to confirm that caller ID information hasn’t been spoofed.
The anti-robocall service is currently available only on the Galaxy Note9, but is coming to other T-Mobile smartphones “later this year”.
The technology requires other telecom companies around the world to also implement STIR / SHAKEN in order to work for all legitimate calls. The North American Numbering Council (NANC) is the governance body overseeing the implementation of the SHAKEN/STIR protocols in the USA.
When caller ID info is confirmed authentic, “Caller Verified” will appear on the phone’s incoming call screen.
