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.

Signal is very reliable now, always getting at least 4 bars which is enough to do everything I need to at a high speed

    This product is a must have for someone like me with limited mobility. As I have a medical condition I have my phone with me at all times and I was worried that I might fall and be unable to get to an area with a good enough signal to call for help. Now I am reassured that should the worst happen I'll be able to contact someone at any time.

        Signal here is very hit and miss. I thought I'd try this and boy does it work. We have 5 bars and excellent reception on all phones now, even better than landline. Simple to register and set up, takes about 1 minute to come online from being off.

          Setting up this signal booster took a little longer than I expected, not too much of an issue though because it now works very well
