How to Use a GSM Signal Blocker
A GSM signal blocker will stop anyone from using your phone to track you. These devices are not only effective at blocking gsm signals, they’re also cheaper than free software. Most of these devices operate on the GSM+GPS L1 combination, the same as most GPS trackers. A GSM signal blocker is designed to cut this connection off completely, eliminating all eavesdropping risk.
These jammers block the signal by transmitting a standard signal on the same frequency as the cell phone. They must be powerful enough to block signals in order to work, which tricked the cell phone into thinking it is in a dead zone without service. The device can only be detected if it is close to the cell phone to function properly. Consequently, if you happen to be in an area where a GSM signal blocker is used, you may be breaking the law.
The first thing you should do is decide which signal you want to shield. There are a lot of different models of cell phone signal jammers on the market today. You may need to choose the one that’s the most effective in blocking gsm signals, or you might be interested in something more specific. For example, if you’re using a GSM signal blocker to protect your office from spying, you’ll want to choose a device with a high-frequency output.
