Well, I thought it was isolated at first, daughter was in Duncan for a regional church conference Thursday through Saturday. She could not call out from inside Duncan but could receive calls she thought. Did not think much about it and then another OSA'r tried to call, I could receive and send their texts, now I don't have an Iphone nor some of the others I have talked too. So, something is drastically wrong, not the phones whatever type but the ATT service has been corrupted or whatever. Even when I tried a friends land line I was disconnected.
