Several reasons why you may need a jammer:
1.Privacy issues:
Some people may think that using a jammer can protect their privacy by blocking surveillance or tracking devices.
2.Avoid Harassment or interference:
There are cases where individuals use jammers to interfere with cell phone signals in public places (such as theaters, restaurants, or libraries) to prevent others from using their phones.
3.Avoid being tracked:
In some cases, you may be tracked by someone with bad intentions, and using GPS jammers and cell phone jammers can prevent others from tracking you through GPS signals and cell phone signals.
