The default way is natted. I believe "normal" users don't even know
about NAT. They just happily surf the net. That's the way the ISP saves
public ipv4 addresses.

It's wireless, not necessarily mobile. Running a server fine here. :)

Earlier this year I converted my ADSL to "doublebroadband" as the ISP
says, now I have dual-WAN in my main loadbalancing router: ADSL 10Mb +
LTE 50Mb.

Native IPv6 with this makes no sense right now because the IPv6 address
changes everytime the LTE connection changes. So I'm quite happy with
the HE tunnel.

Exactly.
