How does it work? I mean, most carrier here in Wurope don't give you an ip, your phone has an internal (10.xxx most of the time but also IPv6 only) ip and you are behind a NAT, which means hundred (up to PAT scalability) of devices may share a common IP. Those API would need the source port number in addition to the IP, is it the case?

So what will happen, if you go to an approved URL, the network will inject headers into the HTTP request that contain you're 10.xx IP address, IMSI, etc, which can allow it to survive a NAT. This tends to get used mostly for internal traffic and partners where an agreement exists, although I think I read once that a US carrier messed up their configuration once and the header injection was happening on every site. For encrypted traffic, I'm not sure what's happening these day's.
