A GSM mobile jammer is a device that transmits signals at the same frequency. When the jammer is turned on and the cell phone signal area is turned off, the jamming part succeeds. The first jammer was developed by the military for communication purposes. The intended commander uses RF communications to control communications between his troops and the enemy. Nowadays, there are more and more mobile users. Therefore, drone jammers are being compared with electronic devices, and turning off mobile signals in some places has become mainstream. A mobile alarm is a tool used to protect mobile phones from receiving signals. The mobile jammer device sends a signal of the same frequency to the GSM modem.

The advent of the 3G network era makes it easier for people to access the Internet. Users still need to rely on 2G networks to make calls and send text messages. 3G can only guarantee normal Internet access. 2G is still the backbone of voice and SMS services. The advent of 4G allows people to watch videos smoothly, but even with the updated 3g, 4g and 5g networks, users are still using 2G networks to make calls and send messages. People use the Internet to bring a lot of convenience, and the 2g network will not stop using, because the basic call and short message service depends on the GSM network. The GSM network is the most basic voice and text communication network service, which has been adopted by all major mobile phone brands to provide the most basic communication services. Therefore, the annoying ringtones and calls are based on the 2G network, so it is very necessary to buy a high-power GPS jammer to solve phone harassment or prevent loud calls.
