Whether you are trying to prevent a prank call or need to keep the peace at a meeting, this device can help. There are several different kinds of jammers, from high-tech devices to low-tech ones.

The frequency band of a mobile phone varies from country to country. The USA and Canada use the 850 MHz band for primary service, while the Middle East, Africa, and Asia tend to use the GSM 900 and 1800 bands for mobile phone signals. In some countries, local carriers use the 450 MHz band for coverage. Depending on where you live, you can find a jammer that can block these signals.

Powerful signal blocker

Prisons, for example, are notorious for having tight security and phone calls can lead to prison break planning. A cell signal blocker can keep people from talking to each other, and prevent the spread of terrorism.

Another great option is a portable signal jammer. This portable device is small and lightweight, making it easy to carry and ideal for protecting confidential meetings and calls. This portable device can block cell signals from a variety of sources from Wi-Fi to GPS and is capable of blocking up to 30 meters of distance. Whether you’re looking to protect yourself and your family from cell phone scams, a portable signal jammer can provide you with the protection you need to get in touch with loved ones without the hassle of a cell phone call.

Environmentally friendly

There are various reasons to purchase an environmentally friendly cell phone signal jammer. These devices can prevent damage to your smartphone by blocking mobile signals. They are also useful for various other legal purposes. One such use of a signal jammer is by technicians who want to check the working condition of their equipment without the need to call 911. Another legal use for such a device is by prisons, where they are used to block cell phone signals. In this way, the device is only effective inside a prison and will not interfere with any commercial signals.

A cell phone signal jammer works by disrupting mobile signals and causing a bubble around them. The bubble created by the device can cause some health effects, but these are minimal if the output power is low or medium. For example, a recent study found that exposure to radiation from a mobile phone jammer affected the quality of sperm. Semen samples showed decreased motility, and DNA fragmentation. Ultimately, environmental protection is the number one reason to use a cell phone signal jammer.


If you are thinking of purchasing a cell phone jammer, you probably want to know its legality. In most cases, jammers are illegal, but there are exceptions. Some countries, such as Israel and South Africa, have banned the use of jammers, while others do not. These are just a few examples. The legality of cell phone jammers largely depends on the intended use of the device. Despite its negative reputation, some users are willing to risk jail time for illegal use.

Although the federal government has not made the device illegal in the United States, it does not apply in other countries. Various websites sell jammers for home use. Law enforcement experts say that cell phone jammers can cause serious harm to people, and if they are a security risk, they are not legal. Nonetheless, many people use jammers to protect their families and friends. There are also plenty of ways to legalize cell phone jammers
