Available in desktop, handheld, portable, and vehicle-mounted models, our omnidirectional＆full-band cell phone jammers are designed to block all wireless communication signals. Prevent remote erasing, hacking, and data theft. Secure your mobile phones.

They effectively interfere with 2G, 3G, 4G, 5G (similar to 5G jammers), Wi-Fi, Bluetooth,walkie-talkies, VHF/UHF radios, drones, remote detonation signals, remote-controlled bombs, cameras, covert surveillance devices, and other wireless systems operating within standard civilian and commercial frequency bands. They only block signals from on-site wireless devices without causing any interference to surrounding base stations.

Ideal for safeguarding confidential environments, preventing unauthorized communication, and mitigating security threats in scenarios such as secure meetings, examination centers, detention facilities, and sensitive government or military zones.

1. What is a cell phone jammer?

A cell phone jammer is a device that disrupts or blocks mobile phone signals in a specific area. This technology can prevent phones from making or receiving calls, sending texts, or using mobile data within its range. They are commonly used in places where distraction-free environments are needed, like theaters, classrooms, or certain secure facilities.

2. How do cell phone jammers work?

Cell phone jammers work by emitting radiofrequency signals that overpower the signals from cell towers to mobile devices. When a cell phone attempts to connect to the network, the jammer prevents it from establishing a handshake with the tower, effectively blocking any communication in the designated area.

3. Can I block cell phone signals in my house?

It is illeagal to use jammers in many places, but you can block cell phone signlas with these alternative measures:

A.Building materials like thick concrete, metal, or even specially coated walls.

B.Setting up a Faraday cage.

C. Signal control solutions like home network extenders or boosters.

4. Do cell phone jammers really work?

Yes, they can block the connection  between the mobile phone and base stations, causing all the phone “No Service” or “Searching”. They are widely used in the seetings where the phone signals are prohibited like various exams, prisons.

5. Can cell phone jammers be detected?

Yes, cell phone jammers can often be detected, particularly in controlled or monitored areas. The detector can identify the location of jammers and some advanced detector can even identify the interference reall-time.

 6. Are cell phone jammers legal?

The legality of cell phone jammers varies by country. In many places, such as the United States, it is illegal for individuals to use, sell, or operate these devices because they can interfere with emergency services. Always check local laws and regulations before considering the use of a jammer.

7. How far can a cell phone jammer reach?

About 100M(dependig on the strength of base station signals). They only block signals from on-site wireless devices without causing any interference to surrounding base stations.

8. What are the main uses for cell phone jammers?

Cell phone jammers are used in various scenarios, including educational institutions to minimize distractions during lectures, in movie theaters to enhance viewing experiences, and in sensitive areas like military bases or government buildings to prevent unauthorized communication. However, their use should comply with local regulations. 

9. Can cell phone jammers affect other devices?

Yes, cell phone jammers can potentially interfere with other wireless devices that operate on similar frequencies, such as Wi-Fi networks, Bluetooth devices, or even some medical equipment. This unintended interference can lead to disruptions in communication and operation, making careful consideration essential.
