This just isn't the case with modern phones. 5G and 4G use active beam forming. It usually only takes a single tower to figure out bearing and signal strength can indicate range. With just one tower, a carrier knows where a 5G phone is within 10m. Combining multiple towers shrinks that rapidly.

I know of a few occasions [0] when missing persons were found stranded in the mountains due to the assistance of cell tower triangulation. That said, it's a pain to get any element of accuracy and in the US, it takes a lengthy legal process for law enforcement to obtain that data.
