i live in grosse pointe, mi outside of detroit and my family is on a plan with at&t. this morning everything was fine. we were getting 4-5 bars like we always do. then all of a sudden, we all get no service. i called a few friends with at&t in the area and they also have no service. this is the second time this has happened in this area. has anyone heard of something like this or know anything about it? thanks in advance.
