the problem is that neither wvdial nor NM are proper telephony stacks.
They are both in the end just dialers. So that comparison is not helping
us since oFono has to do way more work before we can just "dial" an
Internet connection.

We get this fixed, but not as quick as you might like us too. The Huawei
and ZTE modems are showing race condition behavior. And that is mainly
because oFono is just too fast and they can't initialize the SIM fast
enough for us.
