Depending on your cable/satellite provider, if you can get it... They're asking a lot of money for carriage of the new network, more than any other college sports network.
If you have DirecTV, so far there are no plans to carry the SEC Network due to the cost and the trend of all these new sports networks raising their overall costs significantly.
As of today, only AT&T U-Verse and Dish Network have signed on to carry the SEC Network.
