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.

After installing this unit, I no longer experience dropped calls. The service is excellent sometimes I even forget I used to have cell reception problems.

    Our cell reception was spotty at best in our cabin in wisconsin's northwoods-you could typically get a text out if you let your phone lie on the deck but there was no possibility you could get a call through. After installing this over the weekend we were able to create calls, submit tests and surf the internet. I was doubtfull about the price of this booster but we've seen incredible outcomes so far.

      We regularly dropped calls from my main cell service provider, even with the different alternative cell service provider. A change of 128 to 78 was noticed with this. I adored that Amazon masterminded the installation. All I needed to do was affirm the time.

        I can't believe this worked in an area where cell signal is weak. Was quite surprised but in a good way.

          Before buying this booster, I had tried three more, and none had worked. My mistake was I didn't know the frequencies in my area and had no idea where the nearest cell tower was. I ended up buying the wrong units, but once I got in touch with the customer service, they were able to help me find this unit. It works great, and I love it.
