Yes but then also the browser wouldn't work, or does only mms go with ipv6?

So I couldn't try because I have no small sim with mms function.

We need more informations, if you don't have ip6tables command you need to install iptables-ipv6 package.

With active mobile data connection do:
Code:
lsof -Pn -i > netinfo.txt
ip6tables --list >> netinfo.txt
And attach the file please.
You could also check, with lsof command, for connections when you receive a mms.

You could also configure ip6tables to log rejected tcp packages, I would set "--log-level notice". And then you can check with:

Code:
journalctl -k
the rejected connections.
