CVE-2019-20472

Stolen SIM use via forced PIN disablement

Published Nov 7, 2024 · Updated Nov 4, 2025

Security control bypass in One2Track devices as of 2019-12-08 allows physically proximate attackers to use a stolen SIM card without its PIN. The smartwatch's SIM-card handling refuses to operate when a PIN is configured, displays "Remove PIN and restart!", and requires PIN protection to be disabled. Physical possession of the watch is required; removing its unprotected SIM then permits use without the subscriber's PIN.
