This is slightly false in an alarmist fashion. At least in the US, the police are not actively tracking anything without a subpoena to the cellular provider of the phone in question. They can look at the location data after the fact, using a court ordered subpoena. They can also use live location data in an emergency situation,also using a court ordered subpoena.
Cellular data from cell towers on cell networks are private property of the cellular provider companies. That’s not to say you are private while on them. Just that the police are not actively tracking your location through them without great effort for each individual they wish to track.



A VPN does not stop location data for your physical device when looking at cellular data from the carrier. Your location can and is always triangulated using cell towers. VPNs only ever protect your IP address from being geolocated and encrypting the data downloaded and uploaded while connected. Bit streams are still sent and received from a physical place in the world before the VPN hides your traffic and that is recorded by the cell provider.
