FAQ

  • Why a mobile signal booster is the best solution for poor reception?

    A 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:
    1. Use our Booster Finder Wizard to find the best booster based on your needs.

I upgraded from an iPhone 4S to an iPhone 5S that could not receive signals in my workshop. Thus, I lost so much business. Luckily, a friend recommended this booster to me and I didn't hesitate to buy it. It works magic boosting my signals and does not require expertise to install

    We live in Darwin region and we were kind of lucky to get at least one bar of 3G on the windowsill in the living area and lots of dropped calls. With this wonderful booster and an external antenna we now have 3-4 bars through the house and even 4G at times, and no more drop out. I Would highly recommend and although expensive it is nice to be able to communicate with the outside world without having to go outside

      Before installing the unit, we'd get a max of 1 bar at two windowsills in the house. We were unable to make or receive calls; just texting if luck was on our side. Today, I can call and text from any point in the house. I have connected the unit to an external antenna.
      The unit was a little too expensive, so it was a shame that we had to spend too much to be able to use our phones just 30 km from the nearest town. Nevertheless, I cannot regret purchasing the product. I had my doubts at first, but I am happy now.

        I bought the unit to use on our farm, where we barely had mobile coverage before. After installing the unit, we have a strong and stable connection, which enables us to keep the business running. Its ease of use is impressive, but consider lowering the price.

          My friend and I actually placed a bet on whether this unit would work or not. He believed firmly it would. I doubted every word, being the everyday sceptic that I am. I am seated in my living room with a whole five bars on my phone from one bar and losing a bet has never been this exciting. I can place a bet on this unit again and again. It works magic! At least I saw it myself!
