There are several myths surrounding mobile signal boosters that can lead to confusion. One common misconception is that boosters can create their own signals; in reality, they only amplify existing signals from cell towers. Another myth is that using a booster is illegal; however, as long as the device is approved by the Federal Communications Commission (FCC) or relevant authorities, it is legal to use. Additionally, some believe that boosters will interfere with cell signals, but properly installed devices should not cause any disruptions. Understanding these myths can help users make informed decisions about using mobile signal boosters.
