Georgia prisons are rolling out cell phone blocking technology, aiming to eliminate unauthorized inmate communication. The Georgia Department of Corrections (GDC) claims this is about stopping crime and improving security, but history—and the U.S. Department of Justice (DOJ)—suggests otherwise.
This crackdown isn’t just about security. It’s about control—silencing inmates who expose prison abuse, increasing profits for prison phone companies, and worsening already dangerous conditions.
What happens when thousands of inmates suddenly lose their only link to the outside world?Violence, riots, and unchecked corruption.1
How Georgia’s Cell Phone Blocking System Works
The GDC has been quietly installing contraband interdiction systems (CIS) at multiple prisons, including Telfair State Prison. These systems include:
🔹 Managed Access Systems (MAS)
• Creates a controlled network inside the prison, allowing only approved devices to function. All unauthorized phones are blocked from connecting.
🔹 Beacon Technology
• Detects and disables contraband cellphones when they enter a restricted area.
🔹 Geolocation-Based Blocking
• Prevents phones in specific prison zones from sending or receiving signals.
🔹 Micro-Jamming (Legally Questionable)
• Blocks all wireless signals in certain areas, a method that could interfere with emergency communications.
More technical details follow the footnotes.2
These systems are already in place at several Georgia prisons and will soon be turned on. It’s coming soon to a prison near you.
The Unintended Consequences: Violence, Cover-Ups, and Corruption
The Georgia prison system is already one of the deadliest in the country. The DOJ’s 2024 investigation found unchecked gang control, routine sexual abuse, and deliberate staff indifference to violence3.
Cutting off cell phone access doesn’t fix these problems—it makes them worse.
📌 More Power for Gangs
✔ Gang leaders will still communicate. They already control state-monitored phones through coerced access.
✔ Without cell phones, non-gang inmates lose their only way to seek outside help.
✔ The most vulnerable will be silenced, leaving them fully at the mercy of corrupt officers and prison gangs.
📌 Violence Will Skyrocket
✔ Since cellphones became common in prisons, the GDC eliminated nearly all rehabilitative programs.
✔ Tablets, which once allowed inmates to access music, movies, and education, have been phased out.
✔ Now, with nothing left to occupy their time, prisons will descend into chaos.
✔ The likely outcome? More riots, more stabbings, and more dead prisoners.
📌 No More Whistleblowers
✔ The biggest exposés of prison corruption—murders, abuse, medical neglect—came from cell phone footage.
✔ Inmates have documented rampant staff corruption, sexual assaults by officers, and murders that would have otherwise been covered up.
✔ Without cell phones, GDC officials can more easily hide the true conditions inside these prisons.
📌 Families & Legal Support Cut Off
✔ Georgia’s prison phone system is notoriously expensive. With cell phones blocked, inmates will be forced to rely on monitored, overpriced calls.
✔ Legal access will suffer—many inmates use cell phones to research their cases, contact lawyers, and file legal documents.
✔ Inmates who lose contact with their families are more likely to reoffend. Cutting off communication damages rehabilitation.
What Do Inmates Really Use Cell Phones For?
The GDC argues that cellphones only benefit criminal enterprises, but the real reasons inmates use phones paint a very different picture.
✔ Contacting Family – Prison calls are expensive, and many families can’t afford them. Cell phones allow parents to speak to their kids.
✔ Reporting Abuse & Violence – Nearly every major prison scandal in Georgia came from cell phone recordings exposing murders, rapes, and neglect.
✔ Legal Assistance – Cell phones provide access to legal resources, helping inmates fight wrongful convictions.
✔ Mental Health Support – Isolation increases suicide rates. Phones help inmates stay connected and emotionally stable.

What Happens Next?
Other states have already tried blocking cell phones—and the results haven’t been pretty.
🚨 Will Georgia See More Violence?
• South Carolina began implementing cell phone blocking technology in 2021. The result? More riots, more attacks, and no actual decrease in gang activity4.
• Experts predict a rise in unrest, hunger strikes, and violent outbursts—prisoners won’t take this quietly.
🚨 Does This Actually Improve Security?
• Cell phone blocking does nothing to stop corrupt officers from smuggling in contraband, drugs, or weapons.
• If Georgia wants safer prisons, it should focus on:
✔ Hiring more staff
✔ Removing violent gang members
✔ Expanding rehabilitation programs
🚨 Who Benefits From This?
✔ Prison phone companies stand to make millions from increased reliance on state-controlled calls.
✔ GDC officials benefit by hiding violence and corruption from the public.
✔ The real losers? Inmates, their families, and anyone who cares about justice.
Conclusion: Security or Suppression?
This isn’t just about stopping crime. It’s about cutting off communication, silencing whistleblowers, and keeping the public in the dark about what’s happening inside Georgia’s prisons.
Instead of blocking phones, Georgia should be fixing the corruption and abuse that inmates have been exposing for years.
Without public outcry, this policy will go unchallenged—and the suffering inside Georgia’s prisons will only get worse.

- Contraband cell phones have significantly contributed to violence within South Carolina prisons. Notably, the deadly riot on April 15, 2018, at Lee Correctional Institution, which resulted in seven inmate deaths and numerous injuries, was partly attributed to inmates using contraband cell phones to coordinate the violence.

In response to such incidents, South Carolina has been exploring technologies like micro-jamming to prevent unauthorized communications. In April 2019, the Federal Bureau of Prisons conducted a pilot test of micro-jamming technology at Broad River Correctional Institution in Columbia, South Carolina, aiming to block contraband cell phone signals within the prison.

While these measures aim to enhance security, concerns persist regarding their effectiveness and potential unintended consequences, such as increased unrest among inmates and challenges in emergency communications. Critics argue that simply blocking cell phones does nothing to address the root causes of violence—such as staff shortages, gang control, and lack of rehabilitative programs—and instead creates more instability inside prisons.

Technical Breakdown: How Georgia’s CIS System Blocks Cell Phones in Prisons
To understand how Georgia’s Contraband Interdiction System (CIS) operates, it’s essential to first examine how cell phones communicate with towers and then explore how these managed access and blocking technologies disrupt that communication.
How Cell Phones Communicate with Towers
A modern cellular network operates on a system of cell towers, each covering a specific geographic area. Here’s a step-by-step breakdown of how a phone connects to a network:
1. Searching for a Network
• When a mobile device is powered on, it scans available frequencies to identify the strongest signal from nearby cell towers.
• This process is called network selection and is guided by a pre-programmed Preferred Roaming List (PRL) stored on the phone’s SIM card.
2. Establishing a Connection
• Once the device finds a cell tower with an acceptable signal, it sends a Registration Request (Attach Request) to the network.
• The network responds with an Authentication Request, verifying the phone’s SIM credentials and IMEI (International Mobile Equipment Identity).
• If the network recognizes the device as an authorized subscriber, it assigns it a channeland allows communication.
3. Signal Handoff & Data Transmission
• As the user moves, the phone continuously switches between towers via a process called handoff to maintain a strong signal.
• The phone and the tower exchange control signaling via a paging channel to establish voice calls, SMS, and data sessions.
4. Encryption & Network Security
• To ensure security, GSM, UMTS, and LTE networks encrypt communications using algorithms like A5/1 (GSM), KASUMI (UMTS), and AES-128 (LTE).
• This prevents eavesdropping but does not stop a properly configured Managed Access System (MAS) from intercepting and controlling the signal.
How Georgia’s CIS System Blocks Unauthorized Phones
1. Managed Access Systems (MAS)
• MAS technology mimics legitimate cellular networks, tricking unauthorized phones into connecting to fake base stations rather than commercial cell towers.
• This is achieved by broadcasting a stronger signal than nearby legitimate towers, effectively forcing all mobile devices within range to attempt to connect.
Process Flow of MAS:
1. The MAS broadcasts its presence on the same frequencies as local carriers (AT&T, Verizon, T-Mobile).
2. The MAS sends an immediate network attachment request to all devices, forcing them to attempt to connect.
3. Once a phone connects, the system performs IMEI filtering:
• If the device is pre-approved (such as an official prison phone), the connection is allowed.
• If the device is unregistered, the MAS blocks all outgoing calls, SMS, and data.
4. The MAS can then log connection attempts, making it easy for prison officials to track contraband phone activity.
2. Beacon Technology for Detection
• Many CIS systems include Beacon Technology, where low-power radio transmitterssend out signals that can be detected by prison security teams.
• When a contraband phone enters a restricted area, it pings the beacon, which:
• Records the phone’s unique ID
• Flags the inmate associated with the device
• Triggers alerts for enforcement teams to locate and seize the device
3. Geolocation-Based Blocking
• Using GPS and RF triangulation, the system identifies when a phone is inside a specific geographic boundary (e.g., the prison perimeter).
• The system then issues a “location update reject” signal, preventing phones from registering on commercial networks.
4. Micro-Jamming (Selective Jamming)
• Unlike traditional wide-area jamming, which is illegal under FCC regulations, Micro-Jamming uses highly targeted directional RF interference:
• Signal disruption is focused on prison dormitories and yards while leaving administrative areas unaffected.
• The jamming system scans for active cell connections and injects interference only when unauthorized signals are detected.
• Micro-Jamming uses spread-spectrum techniques, making it difficult for contraband devices to circumvent blocking by switching frequencies.
How These Technologies Affect Cell Phone Use
