Good luck on Sardis with AT&T. Their coverage is really bad and spotty. It seems to be really bad on weekends. I have to move to certain spots on the lake to return important calls. Often wondered if it's a bandwidth issue. At my Father-in-Laws house on Sardis Lake Road, I can get reception in the back bedroom but nowhere else in the house. I can go outside by that same bedroom and no reception. Verizon is good there..
