Yes that don't have to allocate an IPv4 address for each customer or deploy ugly solutions like CGNAT. They simply cooperate with phone OS makers (Apple and Google) to make sure the OS and the apps work in an IPv6-only environment. Apple then forces app developers to make their app work in an IPv6+NAT64+DNS64 environment.
