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:

Whilst this product does work, it won’t fix your phone or network - if you've got zero bars to start with you can't expect miracles. But it will improve it so if you're looking for a little boost you'll be happy.

    I went from no signal at all to 4 bars LTE, and I couldn't be happier. I used this booster in my 600 square ft cabin and got a strong signal throughout. This product does what it's supposed to do.

      Whilst the signal booster does work excellently downstairs, I have issues getting full bars upstairs.

        I bought the cellular signal amplifier for my home. Before then, my cell phone had 2 bars in the living area and 1 bar in the other rooms. Ever since I installed it, I have been getting a strong 4G Internet and4-5 bars everywhere in the house.

          Bought this for my parents as they are very rural and can't get good service in their house. Now they do. Even though it is supposed to be for just a single room, they swear that it improves their signal throughout their house. 0-1 bar before, now 2 bars throughout the house
