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.

  • Does this need installation? Can I set it up myself?

We had purchased a cheaper unit from Amazon, and it disappointed. It would provide 3 bars max when it worked. This booster though is fantastic. We no longer have to keep running upstairs to take a call. I haven't had any issues yet.

    I have an office in a pretty congested building. Sometimes the network is good; sometimes you can barely make a phone call. This inconsistency pushed me to buy this signal booster, and I don't have to worry about cell coverage anymore. I'm pleased with this device, and I'd recommend it anyone with a small office/home.

      I believe for us the product is doing a good job so far. Initially, service was still low but after setting it up, however, I believe it was my phone. I kept on getting poor cell reception and thought the product was not operating, however, I checked the signal with another phone and it worked amazing. Currently, after many months everything is functioning well.

        I was having very erratic signal patterns in my house. The same room would yield three bars after a lot of convincing, but would drop to one and plain refuse to go any higher. My neighbour who had the same problem before suggested this unit to me and since she spoke so highly of it, I went out and purchased it. It has worked so perfectly that I think it was made with me in mind

          If you are looking for a mobile signal booster that will actually do the things that are listed that it would do, then this is the one for you. I came across it after one bad experience after another, and a great deal of disappointment and dashed hopes. It restored my hope in these things just when I was about to totally give up. You should totally go for this unit if you need a serious solution to your network problems.
