I know the service/device uses VPN if you are using "wifi assist" to
connect to an open WAP -- it automatically tunnels the traffic so it can't
be read by nearby snoopers. Perhaps they employ a similar technology or are
using something like PPP to take all of the traffic back to one (or many)
"access servers" before sending it off to the Internet. I have no
experience whatsoever in cellular network operations, but I know many
providers employ similar methodologies to assist in meeting their CALEA
