You are... Wrong again :/
From Wikipedia https://en.m.wikipedia.org/wiki/Mobile_phone_tracking
Mobile phone tracking is the ascertaining of the position or location of
a mobile phone, whether stationary or moving. Localization may occur either
via multilateration of radio signals between (several) cell towers of
the network and the phone, or simply via GPS. To locate a mobile phone
using multilateration of radio signals, it must emit at least
the roaming signal to contact the next nearby antenna tower, but the
process does not require an active call.
I recommend you to read the "Privacy" section of that Wikipedia article.

Protocol security vulnerabilities
Several SS7 vulnerabilities that allow cell phone users to be secretly
tracked were publicized in 2008. In 2014, the media reported a protocol
vulnerability of SS7 by which both government agencies and non-state actors
can track the movements of cell phone users from virtually anywhere in the
world with a success rate of approximately 70%
