Several methods to choose high-quality mobile phone jammers
How to choose a mobile phone jammer?
1. Make sure you know your network frequency. In Africa, Europe, the Middle East and Asia, most regions use the 900 MHz and 1800 MHz frequency bands.
2. Make sure you understand the local communication service provider. In France, the largest providers are 3G, 4G, CDMA and GSM. Before buying a mobile cell phone jammer, you should check it on the Internet. The signal jammer can provide you with complete information about the Verizon frequency in your area.
3. Determine the required interference range and application purpose. For smaller areas (such as classrooms), a small and movable area is sufficient. However, if you want to use it in a theater center that can accommodate 10,000 seats, you need to purchase a large-capacity mobile jammer with a wide interference range.
