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.

Product as described. Unfortunately did not work for me, my location not the product the issue. Mobile Signal Boosters UK honoured the 30 day guarantee so would recommend them as a company

Joy Verified Customer2026/02/19

This booster was installed at our workplace. We have a metal roof and no one could get signal in their offices. Sometimes you could get a text through. it would just go straight through to voicemail. We installed the antenna on the roof line outside and ran the cable inside to the base unit centrally located in our office. Now everyone in our office has increased signal strength on our phones and we can make and receive calls in our office now without having to go outside. It really does what is said. I bragged on it to my husband, who is the manager of a company branch and they also could not get signal inside their building. They ordered this and installed it, and they also have full use of their phones inside the building. It has made a huge difference in both of our work places. I would definitely recommend this boost to anyone who needs more signal inside their home or office.

With this booster I now get at least 2 bars better than I used to, great result

Finlay M. Verified Customer2026/02/04

We live in the country by a lake with a lot of trees 20 miles from the nearest "city". Before purchasing this booster, we received no cell phone service at all - now it is clear and strong. Easy to install.

Ryan H. Verified Customer2026/01/23

My business relies on my clients being able to contact me, so a good signal is a must. I installed one of these to make sure I didn’t drop essential calls.
