One call can change it all.

From powering the world’s first phone call in 1876, to helping NASA call a man on the moon 290,000 miles away, and creating the life-saving 911 emergency system—connecting people for good is what AT&T does best. Just as these stories of Lizette and Ramon Salas, and Jason Preston show. Whether it’s a single phone call or uploading a video, when you have the power to connect to others, anything can happen.
