No phone is completely untrackable, but some offer extreme privacy by removing default trackers, using hardware kill switches (like on the UP Phone or Librem 5), running privacy-focused OSes (like GrapheneOS on Pixels), or being simple "burner" phones with no location services. The key is minimizing digital footprints with de-googled systems, physical switches, and careful usage, though any device connected to networks can potentially leave traces.
The Librem 5 separates the cellular modem from the main CPU and memory, that physical isolation is critical to securing the rest of the phone, operating system, storage, and memory from the cellular carrier firmware and towers.
