The installation guidelines are self-explanatory. You don’t have to be a technician to install this unit. I like this product. The mobile signals are now stronger.

    Kieran W Verified Customer2023/08/07

    Mobile Signal Boosters sold me the booster at a reasonable price. However, I didn’t know where to plug in the power supply at first.

      Joe Kaur Verified Customer2023/07/31

      The booster’s compact and stylish design got me in love with the device. Equally important was its efficiency and high quality. It occupies just a small space, and it’s barely noticeable.

        Kyle Fuller Verified Customer2023/07/21

        I have never bought a product from Mobile Signal Boosters before. This was my first time. The delivery was prompt and consisted of everything listed on the website. Upon delivery, the support staff guided me to configure the unit over the phone.

          Anthony H Verified Customer2023/07/12

          When I was hunting for an amplifier brand, I wanted a compact one because my house has limited space. When I placed my order, I had doubts about its performance, but the unit proved me wrong. It has really strengthened the signal inside my house.
