Just make sure to install it in each vehicle according to the instructions provided in the manual. 7. Is the mobile signal booster harmful to my health? - No, using a mobile signal booster is safe. It can actually help reduce the radiation intensity from your phone by providing a stronger signal. This means you'll use your phone less intensively, which is better for your health. 8. How many people can use the booster at once? - The mobile signal booster can support up to 10 users at the same time. This means everyone in your vehicle can enjoy better signal strength for calls and data! 9. Is the installation complicated? - Not at all!
