Fast Facts
- The FCC will vote on November 19 on allowing state and local prisons to opt in to cellphone jamming.
- The proposal aims to stop inmates from using illegal phones to continue criminal activity.
- Jamming remains prohibited for non-federal entities; the plan would require safeguards against interference beyond prison grounds.
- The move reverses the FCC’s longstanding opposition, amid concerns about emergency communications and misuse of jamming technology.
FCC Chair Wants to Let Prisons Jam Illegal Cellphones
A proposed shift in prison phone policy
The Federal Communications Commission plans to vote on whether state and local prisons and jails may use cellphone jammers. The vote, scheduled for the agency’s Nov. 19 open meeting, could mark a major change in how the government handles unauthorized phones behind bars.
The proposal would let correctional facilities choose whether to use the technology. It would not require them to do so. Today, federal law generally bars nonfederal organizations from using equipment that disrupts communications signals.
Prison officials say illegal cellphones can help inmates maintain criminal networks beyond prison walls. A smuggled phone can also give someone a way to threaten witnesses, coordinate crimes or contact victims. For families, however, reliable communication with a loved one in custody can offer connection and reassurance. That makes the policy’s reach and safeguards especially important.
The proposal would create a formal path for state and local facilities to use jammers. It could also set a clearer framework for federal facilities. In 2018, the Federal Bureau of Prisons began testing “micro-jamming” technology to block unauthorized cellphone use.
Potential benefits come with real risks
A jammer disrupts radio signals, such as the signals phones use to connect with cellular networks. In a prison, that could prevent an unauthorized phone from making calls or sending messages. The approach may help officials address a persistent security problem without relying only on searches and other enforcement measures.
Still, radio signals do not stop neatly at a prison’s walls. A poorly controlled jammer could disrupt nearby residents’ calls, interfere with emergency communications or create problems for public safety agencies. A device that affects legitimate users could turn a security measure into a community hazard.
The FCC has long opposed prison jamming in part because of those concerns. The agency says facilities that adopt the technology would have to show that it does not cause harmful interference outside designated areas. That standard matters. So does independent testing, careful monitoring and a clear process for responding when a jammer affects someone beyond prison grounds.
The proposal also raises a broader security question: Who controls the equipment, and how do officials prevent misuse? Giving more facilities access to signal-disrupting tools could create new risks if people use the technology carelessly or exploit it for another purpose. Strong limits and oversight would help protect the public while allowing prisons to address illegal phone use.
Choice, safeguards and public trust
The FCC’s opt-in approach gives each state and local facility a choice. That flexibility could help officials weigh local conditions, costs and security needs before adopting a system. At the same time, voluntary use does not remove the need for consistent rules. People outside prison grounds should not lose access to calls, emergency help or other essential services because of a correctional facility’s equipment.
The timing also fits a wider debate about communication in prisons. In July 2025, the agency said it would delay a plan to cap rates for prison phone calls. The two issues involve different policies, but both affect how people in custody connect with the outside world — and how families manage the cost and reliability of that contact.
If the FCC approves the proposal, the value of the change will depend on how well facilities balance safety with public access. Jammers could make unauthorized phones less useful. Yet the technology must stay within strict boundaries. Clear rules, transparent performance data and meaningful accountability can help build trust in a policy that affects inmates, families, prison staff and nearby communities.
