FAQ

  • Why Signal Hero mobile signal boosters is the best solution for poor reception?

    Signal Hero 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.

I've had to cross my fingers every time I made a phone call until I invested in this signal booster. Now I know the phone will work.

    It took a few days of tinkering but I finally got my signal booster working and I'm glad it does! It's boosted my phone signal by about 2 bars. Good job

      Although I could get a signal on my phone in our office, a couple of the other staff on the Vodafone network couldn't. I saw this booster was supposed to work especially well for the Vodafone network so I got one. It has made it easier for them to use their phones in the office.

        Finally I have consistency! I couldn't understand how one or two of the rooms in my house had a great signal and others had virtually none, but I don't need to even think about it now that I've got this booster. I've finally got consistency throughout the house!

          I am greatly pleased with how strong the signal at my house is currently, I expected a change. I just did not expect how tremendous the change would be and how long it would last. I am still getting used to making calls anywhere I would like to, and not having to spend time by the window hoping for an added network bar. This truly is a very reliable company.
