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.

This product works great when we host large social gatherings as people never used to get signal in my house and now they do

    I've put up with a bad signal for so long that I thought there was absolutely nothing to be done. I've switched networks three times and to no avail. Now I've got this booster there's a big change. I wish I'd known then I could've stayed with my original network.

      I really hate using the phone, so the live chat function was a life saver when I couldn't sort my signal out. A fast response and courteous attitude.

        I'd only had my first model for around 5 weeks before I realised there was a problem. It kept switching itself off and would have be turned back on again repeatedly. When I called the customer service team, they said I could use the warranty because it was within a 2 year period. Since it was faulty, I was sent a nice new system which works brilliantly.

          It seems that this signal booster has done its job as I no longer have poor signal in my house
