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.

I love the product. I have a home version of the booster from the same brand, and it works just as well. I'd strongly voucher for the company.

      I live in a rural area so cellular signal is very limited. I purchased boosters for both the home and car. Signal now is excellent. When I installed the home booster, I had a small issue with setting it up. I called the customer support number and actually spoke with someone who knew what they were talking about. Also I wasn't placed on hold for an extended period of time listening to 'elevator music'. The representative was able to walk me through the issue. Within a matter of minutes I was up and running.

        After installing the amplifier in my truck and connecting it to an external antenna, I can attest that the investment is worthwhile. Before the installation, I received ABSOLUTELY NO signal but now, I just have to switch the unit on and in no time, I get a stable 4 bars. While I use my phone to navigate using Google Maps, I use the computer or tablet to check the status of my work. This is the best package ever as it always has me covered. I'd highly recommend it to truck drivers and like-minded people. Just ensure that the booster is set quite far from the external antenna for optimum results. You'll remember this advice when you have an emergency.

          Was nice and easy to setup and has boosted the signal quite nicely.The cable have an adapter on them which makes them the right size to fit the antenna and booster, which was great for running the cables as I was able to remove the adapters and only had to drill a 10mm hole to run the cable through the walls. Was happy about this as the adapters are about 20-25mm in diameter. The bracket that comes with the yagi antenna is a bit flimsy, and I am a bit worried about how it will withstand high winds, as it does have a large surface area...
