They do it exactly for the purpose of fighting the exhaustion of non-private IP addresses. Just checked with my 3G stick (which I otherwise rarely use), using the default APN I get an IP from the 10.0.0.0/8 range.
I was trying to be civil but if you are going to roll your eyes, let me emphatically say that you have no clue what you are talking about and yes the private range is used to avoid using public IPs but regardless of how much private IPs you use INTERNALLY and how often you use NAT, the public IPs are REQUIRED for it to work on the internet, collectively referred to as the cloud. I am not going to debate someone who has nothing to add by condescension and lack of knowledge. NAT is used to route a bunch of internally configured IPs to a single or multiple public addresses, not to route a private IP. Private IPs are NOT routable, period, using NAT simply manages them within a network, NOT ON THE WAN side but on the LAN side. Your 3G stick is using subnetting, whereby an entity will allocate IPs internally to different groups and then using summary or simply super-netting to use a public IP to give them access to the internet, doesn't make the Class A/10.x.x.x/8 routable or public, NAT or not. The life cycle of your 10. IP ends at the router and sometimes even at the switch if you are dealing with VLANs. Your router's WAN exit interface, AKA, the gateway to your 10. IP, is the one that is public and will see the world, not your 10. IP. Also when it comes to private IPs of Class A 10. or Class C 192.168. no one has to give you squat, it doesn't belong to anyone because they are not public, no ISP will give them to you, you can use them all you want, the public IPs are the ONLY thing an ISP can GIVE you. In fact the ISP's responsibility to your network ends at the demarcation point, where they give you the link to the internet, the internal network topology, is your problem. Just like theirs is their problem, you don't manage or control it.
