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.

Our recently acquired house is on salty water. Practically all the outside parts were structured in view of this. Regardless, the pole mounting section was not built for saltwater and will need supplanting after twelve months as it is now rusting. Would suggest better equipment for the radio wire pole. Would pay the additional. As a replacement method, I need to scale a 50' stature to supplant. Would like to gamble my life only one time. The uplifting news is we currently have generally excellent cell service inside our home and no longer need to locate that unique spot outside our front entryway. We can now truly appreciate living in our home in a genuinely remote saltwater region having great cell get to.

      Our home phone had flashing lights most of the times due to poor cell service. The flip phone was worse since it practically had zero cell signal. The internet connection of the flip phone had at most 1-2 bars of signals. I installed this booster and I can now get 4 bars on my flip phone and the home phone no longer blinks. this product works perfectly just make sure to put the antenna at a very high point. I had mine at above 30 ft.

        I decide to get my sister a signal booster as a birthday present. She used to frequently go to the flag pole to get better reception and send an email. Most of the times we used to get at least one bar of cell service. I can comfortably assure that after we set up this product we got the better signal we could even get 4bars of cell service. Everyone in our house can make calls and send emails at ease at any spot.

          This unit has been great. I went from no signal inside the house to having cell service in every room. I highly recommend it!
