Its not on google, you need to dig through all the NTSB accident reports for air ambulances in the carolinas. I read it years ago. Its there, its just obscure. Im still looking for it too.

Analogue cellphones would interfere with the ILS back in the day. Planes are complicated. No one could guarantee that any kind of radio transmotting device would 100% not interfere. So out of an abundance of caution it was banned for a longtime.
There is an actual air ambulance accident in North Carolina where the flight nurse turned on the cell to contact the ground ambulance on short final in nasty weather. The radar track showthe aircraftveering off at the moment the cell was turned on and hitting a hangar next to the runway. Probably caused by cell unterference making the ILS needles veer off.
Digital cell phones with narrow band transmitters and airplane mode have mostly eliminated that threat, but the FCC still has rules.
However the new 5G cell towers interfere. This is because manufacturers of avionics were lazy, and didnt make their recievers discrete enough, so they get intereference from frequency bands adjacent to the ones use by 5G towers. As a result we have to comply with reduced minima at a lot of airports with 5G towers nearby.
This is all greatly simplified. Here are some links.

Ill tryto find the crash report for the one, but Its the only actual crash I know of and it was a speculative cause as there were no flight data recorders.
Aviation regulation moves slow because of safety implications.

Only if its an airliner full of people, little planes crash every day and no one gives a shit.
This happened more than 15 years ago too. I was reading NTSB accident reports for a project for an airline I worked at when I ran across the report. That was 15 years ago, and the accident happened even further back in time than that.
