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'm cautiously optimistic I've had this for a week now and so far it has given me cellular and data service where I have not had it before. Some spots had static while talking. But I never had any service in those spots before.

    I bought this signal booster sometime last month, and it works great. You just have to aim the outdoor antenna to the cell tower and follow the installation procedure then you are good to go.

      What impressed me most is that this device is affordable and at the same time does what it claims to do. I would barely walk around making a phone call fearing the signal would drop. Now I get to move anywhere in the house and still get 5 bars of service.

        We live on top of a hill approximately 38klms from the OtherProviders tower and at the best of times it is hard to signal outside let alone inside the House. As we can not get any type of Internet apart NextG or Satellite the cheaper option is NextG which works well when you can get the signal. We can now easily make phone calls and browse the Internet from inside the House without the dropout frustrations.

          I took a chance on this booster for my small office. Here cell signal is as poor as it gets. On a good day, we are lucky to get a single bar and most times network is simply non-existent. I bought this signal booster and mapped out the best cell tower that provided the best signal and ever since I get 4-5 bars.
