The Journey of a Text Message
Description:
A simple message sent from a smartphone can pass through several communication systems in a fraction of a second.

What happens after you press send?
When you send a message, your device communicates with a network that transfers the information toward its destination. Depending on the service, the data can travel through cellular networks, Wi-Fi, and internet infrastructure.
The recipient's device then receives the information and displays it as a message. The entire process is designed to happen quickly and automatically.
