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.

Mr Robert Verified Customer2026/07/11

Our office is made of metal and up until we purchased this booster kit, encountered problems getting cellular reception. We had to go outside to use the phones, and 4G internet was unknown to us. When we installed the kit, we started getting stable 4-5 bars, clear calls and 4G Internet

      Previously, we received 1 or 2 bars outside the house. The kit boosted our signal to 3 or 4 bars on 4G. It has been very convenient. The booster is in the middle of a trailer while the antenna is mounted on a tall pole. It offers value for money, and we recommend it to others!

          If you're expecting to go from zero to five bars you might be disappointed, but if you're just looking for a moderate improvement you'll be happy
