A lot of mobile telcos use IPv6, but there are virtually no telcos around the world that don't force the use of some form of NAT (CGNAT, NAT64) for connecting to legacy sites. NAT64 is effectively another form of CGNAT, you only have a proper end to end connection if you're using IPv6 directly.

TMO US has 110 million customers, but they don't have 110 million legacy IP addresses, and most other telcos are in the same boat.
