I am availing AT&T cell phone since last three years; they provide a good network service. But since last few days I am facing problem with AT&T cell phone coverage network. My cell phone is not getting proper signals coverage any where nether in office nor at home. I want to know from the AT&T cell phone user that whether really there is any problem going on since last few days or does my cell phone is damaged and not capturing the signals properly. Please do shear your views with me as I am really facing a big problem due to improper signals?
