I was wondering about that; I played with the initial bearer config a
little bit to see what would happen, but nothing seemed to change the
symptoms I was seeing. I'll try to grab some logs from the modem but
the Quectel tooling is always a bit funky and I don't know if I have
any Windows devices I can drop this in to grab the modem logs... My
laptop, maybe, but that's probably suffering from acute Dell vendor

I've been using v4v6 for the connection setup, but the entire NM
configuration is "just" (and yeah, this worked previously)
