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 booster was easy to install and made an immense difference with my cell phone calls.I was not able to call out or receive calls prior to booster installation. The instructions were easy to interpret.

        Although I love this product, what I liked best of all was the great customer service I received. When I had a problem with my initial order, I was treated courteously and politely. Something that doesn't always happen these days. Absolutely great.

          I have used the booster for a month now, and it ensures that I have cellular reception o. Despite being compact, it works as advertised. Mobile Signal Booster sent the full package to me, the user manual and the warranty.
