AT&T Is Now Blocking Robocalls by Default, a First for Cell Phone Providers

AT&T just announced an expansion of its Call Protect service that will automatically block robocalls suspected to be fraudulent free of charge. Users are also free to manually block individual numbers of known spam callers. But if a consumer wants to automatically block all robocalls, even those from legitimate businesses, it will cost an additional $4 a month.
