    Best experience ever

    Folks, I'm writing to help others with the same issues like I've had. If you have signal probles, refer to this company, because they;re providing the best solution in NZ.One thing for you to take into account when installing the unit, you should research the closest tower that your provider uses. Also, very important point is that there must be a signal at some part of your area to start with
