FAQ

  • Why a mobile signal booster is the best solution for poor reception?

    A 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.

I was experiencing a very poor signal from my cottage but after I had installed the booster I was able to get full signal compared just to one bar before. I can now comfortably browse the internet and watch YouTube videos. Straightforward install and great performance.

    I used to get zero to one bar when I was indoors. Talking from within the house used to be a major problem. On installing the product we are now able to receive up to three bars. We can now Netflix and use the internet at ease.

      Residing in a rural area I was skeptical about purchasing this product.After I was able to locate the closest cell phone mast it was then simple to configure with the Open Signal app and it operates like magic.

        This framework is stunning, it is anything but difficult to install it's ready to use once set up. I put the radio antenna confronting the general bearing I think the pinnacle is found and it brought my signal from 1-2 bars 2g under the most favorable circumstances to full 4g LTE. It got dull before I could complete the installation process however, in the event that it does this well with a fundamental set up a changeless introduce will be the ticket. I live in provincial America with no land-based rapid Internet so I needed to go with mobile unlimited at the tune of $300 every month, presently with this framework, I can use mobile unlimited but a small amount of the expense and it will pay for itself.
