Paradoxical Traveler

I move without wheels, I fly without wings, I carry loads yet leave no trace. I traverse great distances in an instant but can also linger in place. I am essential for communication, yet I make no sound.
People rely on me every day, often without realizing my presence. I can bring people closer together or create vast separations. Without me, the modern world would be disconnected and isolated.
What am I?
