Signal jamming devices (e.g., cell phone, GPS, and radar jammers) can prevent you and others from completing 9-1-1 and other emergency calls.

Use proximity avoidance. Typical cell phone jamming systems are meant to reach distances of approximately 30 feet. Drive or walk away from the jammed area to receive calls.
