A:Answer I will answer with the best of my knowledge. I bought that tablet for my sister. I have a Galaxy s6, and it is working great on my T-Mobile Service, and my ATT Internet. And it is a Verizon tablet. I will say that that Galaxy Tab A8 is a great tab to have. I am sure that it will work with your ATT, because I set up my Sisters Tab A8 with my ATT internet, and it worked great. Enjoy it. I am sorry for the late response. Email issues:(
