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.
Yes. This is exactly the type of situation the booster is designed to improve. The system captures the available signal outside your building using the aerial, then amplifies it and distributes it indoors through the internal antenna. When there is usable signal outdoors, the booster can significantly improve indoor coverage. Customers typically move from unreliable indoor signal to stable, usable coverage that supports clear calls and consistent mobile data throughout the coverage area. If you are unsure about signal levels at your property, our team can guide you before or after purchase to help optimize the setup.
