What is "Spoofing"?

When data is not transmitting over the connection for a period of time, the connection "spoofs." When a connection spoofs, the phone connection is dropped and a placeholder is reserved in the server. Once the user sends data (e.g. click on a hyperlink or send an email), the phone automatically dials back into the system and the connection is reestablished almost immediately. This feature reduces airtime and improves the phone's battery life.
