The security indicator
is displayed during a connection if the packet
data transmission between the radio and the gateway (identified by the
) is encrypted.
The security icon does not indicate that the packet data transmission between the
gateway and the content server (or place where the requested resource is stored) is
secure. The service provider secures the packet data transmission between the
gateway and the content server.
