Before you cancel your cable or satellite service, you need to find out if you will be able to stream TV. Check your bill from your Internet provider and see what speed you have. Netflix recommends 7mbps for streaming HD content. I recommend 10mbps. (I have 20mbps.) Then go to speedtest.net and make sure you are getting what you are paying for. Also, on your bill, make sure you have unlimited data. If you have any sort of data restrictions, streaming TV is NOT for you. If your speed is not up to par, contact your provider and find out if a faster speed is available and what the cost is. Know all of the costs before you make the leap!
