Cell site emulators/IMSI catchers/Stingrays are also popular, particularly with the feds. Our state has some pretty strict privacy laws. But they mean nothing when it's the FBI/DoJ setting the sites up
These don't work with 5G because the comms with interesting information is encrypted between the handset and the network core (not just the cell.) That includes the IMSI. These IMSI catching devices work up through to 4G. 5G and beyond, no. If you want to be paranoid, get worried every time your cell phone shows "4G" on the screen rather than "5G"
