I have has native IPv6 since 2010, from two different ISPs.

It is also available for one of my phone contracts but not tried enabling it yet.

Well, you're very lucky (genuinely).

In 2025, I tried to access my services using IPv6 with 4G phones and different subscriptions (different ISPs), fact is, many (most?) of them did not support IPv6 at all :(

I had to revert to IPv4. And really I have nothing against IPv6, but yeah, as a simple user, self hosting a bunch of services for friends and family: it was simply just not possible to use only IPv6 :(

(for context, the 4G providers are French, in metropolitan France)

My phone contract that does offer IPv6 is with Free, I could not work out whether it would disable IPv4 if I enabled IPv6 so have not tried changing it.

Conversely, I had IPv6 for about 5 years from an ISP and when I switched providers, the new ISP was IPv4 only. A few years later and they now support IPv6, but my firewall setup is now IPv4 only, so I've not bothered to update it.
