Correct. I have a friend that leaves his phone in his vehicle because the facility he works in as a contractor requires security clearance &amp; doesn’t allow any devices. Jamming is 1000% illegal.

Yep, my work basically bans cell phones from entering the building for people who work on site, you either leave them in a locker or in your car.

Technically you could carry it but if found you were getting fired.
