Bandwidth settings will be fully configurable. You will be able to customize how much bandwidth your HoloPort can consume by limiting it to a certain amount or by setting up an autopilot to schedule bandwidth use only at certain times, or assign bandwidth use only to certain apps or apps that pay above a threshold. You could also configure it to only run at night when you aren't using the internet connection, or run slower when you are using a bandwidth-demanding application, such as watching Netflix.

Will my ISP charge me more?

You should not be charged by your ISP to add a new device to your home network, but you may be charged more depending on your current ISP bandwidth usage limits and if you pass this. Please check with your local service provider.
