FAQ

  • Why Signal Hero mobile signal boosters is the best solution for poor reception?

    Signal Hero mobile signal booster is the only working solution if you have a weak signal and dead zones. It helps to improve signal strength so you can access the internet more quickly, and stream videos without buffering.

    With our booster you can make and receive calls without interruption, ensuring you're always in touch with your family and friends.

    In general, the booster catches the signals from the nearest cell tower in the area by the external antenna which is included in the kit, then it sends the signal to the booster box. The box amplifies the signals, ensuring reliable coverage even in areas with poor signal strength, and the internal antenna spreads the signals inside the closed area.

  • Please, help me to find the best booster. How do I know which one?

    If you want to find the best booster for you there are 2 easy options:

          I have just installed the booster kit, and the signal has increased from zero to 5 bars at any point in the house. I feel like doing away with the fixed line now.
