Fragmentation isn't supported by the peer AFAIK.

I have now tried 4 different SIM cards (different providers and/or services).
There is only one provider/service (unfortunately the one I have used more than a
week now) which doesn't work. The rest works, i.e. my tunnels come up without
problems so far!
Summarized I can say the tunnel works with Ethernet and at least with three different
Mobile providers/services. I doesn't work with one provider. I don't have access to
other providers/services right now.
I will try to get information about the subject from this provider (which will be
complicated I suppose).
The outstanding quality of your feedback helps a lot.
Thank you very much!
