What allows them to work with v6 in such an efficient manner?
A piece of client software is installed on every phone that presents
an IPv4 address to the phone and then translates packets to IPv6 for
relay over the network. This works because T-Mobile has considerable
control over the phone.
FWIW, this software component (the CLAT) can also be on the CPE edge
router which many ISPs either control outright these days or at least
can influence.
