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.
    2. If you’re still having trouble finding the right booster after using the Wizard, contact our technical support team via chat or phone. They’ll be happy to assist you in finding the best solution.

The signal boost I’m getting from this device is phenomenal and a huge improvement over the old situation. However, I would recommend you take time in the installation and adjust the location of the antennas until you find the best possible spot.

    Amazing product. I love it. Not only is it affordable but works as advertised. I might consider buying my mom one like this to improve cell signal in her house as well.

      I am beyond impressed with this signal booster. It took my signal from weak to a strong 5 bar service. Now, everything I do in my office; whether its calling or sending and receiving emails is so efficient. I love this item. It's a lifesaver.

        My wife and I recently moved out of town and settled to a new house with almost zero cell service. At first, we didn't know how we were going to deal with this problem until we bought this signal booster. After installing it, our cell signal is always bouncing between 3-4 bars, and I love it. Sometimes I forget I don't live in the city anymore.

          I live with my family in a valley, and the best we get in terms of reception is one bar. We bought this unit and crossed our fingers that it would relieve us from this misery. Its installation took some time as we were trying to figure out the position for the outdoor antenna. Once we were able to solve that, the device worked fantastically, and everyone is just too happy.
