After the attack, the cell phone network of New York City was rapidly overloaded as traffic doubled over normal levels. Since three of the major broadcast networks had their transmission tower atop the North Tower (One World Trade Center), coverage was limited after the collapse of the tower.
Emergency relief efforts in both Lower Manhattan and at the Pentagon were augmented by volunteer amateur radio operators in the weeks after the attacks.
After the planes struck the World Trade Center, people inside made calls to loved ones; in many cases, the last ever heard from them.
AT&T eliminated any costs for domestic calls originating from the New York City area (212/718/917/646/347) in days following.
