Is there a possible way to block a phone number in AT&T wireless? There are some people who call me many times a day. I don’t want them to call me again. Their calls irritate and disturb me. I want to track these anonymous numbers to the actual phone that it was dialed from and actually block those numbers from calling me again? I want to know about a way to actually trace the caller with their phone records and block them forever for calling me on my number in AT&T wireless network.
