Silent network verification

Silent network verification asks the mobile network, in the background and over mobile data, to confirm that a phone number belongs to the SIM in the phone making the request, with nothing to type.

Also known as SNV, also called silent network authentication

Glossary, A to Z

There is no code, so there is nothing to phish or forward. It confirms the number; who is holding the phone is the question SIM and device binding answer, which is why the two are paired.
