  Jamming cell signals isn’t foolproof. Cell phone jammers also have a human component. Blocked signals affect legit phones as well as the contraband ones. Mobile reception is blocked entirely, jamming blocks all phones and SIM cards within the jammers gps reach.

  Guards and other staff can “accidentally” cut the power or otherwise disable jammers. Even short outages allow phones to connect to the outside world.
