I am looking at internet options and considering Exede as it is one of our limited options. I have a few questions in trying to make my decision. Is there a trial period if we are not satisfied after install? I understand the advertised speeds are "up to" that amount, but how often and a what times do speeds actually reach maximum? I also see a lot of recent posts about data usage when no devices are connected. How does everyone typically avoid this? I am concerned about spending the money on installation and locking in to a contract to only find that our area has the least receiption available. Thank you.
