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?

    I was getting really sick of being told that I had voicemail waiting every time I left the house. All my calls were being dropped because of the dodgy signal. Since I got the amplifier I don't have to constantly call my voicemail to catch up on messages as everyone can get through first time.

      I've been with EE for years now, and have always struggled to use my mobile in my house unless I stand in the corner of the bedroom. Thanks to this booster I can now get a signal downstairs too.

        I'd got used to not being able to use my mobile in the house, but after my son bought me one of these I was amazed to unlock a whole new lease of life from my phone! Now I'm streaming from YouTube and Spotify every night when I can't sleep!
