Hi,
I got this case again.
Killed ofono and checked the statuses manually. The output is below.
Its clear that creg and cereg both reports roaming, while cgreg reports unknown.
This is a different case? Your originally case had CREG reporting
unknown while UREG reporting LTE.
Denis if netreg would be updated, I still think we have an issue with
atmodem/gprs.c.
The problematic part is when at modem received the cgreg and calls
ofono_gprs_status_notify, the gprs core part will then detach.
The log when this happened:
May 13 05:33:37 ofonod[741]: Aux: < \r\n+CREG: 5,"0080","00000006",6\r\n
So we are roaming...

Weird that you're using this magic. I thought only the Freerunner modem
had this issue. But ok...

So for whatever reason the modem (or network?) decides to detach GPRS...

../ofono-1.29/src/gprs.c:gprs_set_attached_property() 1 -> 0
My memory is fuzzy now, but I'm not sure if we ever put in the logic to
attempt a re-attach in such a situation (e.g. we didn't request a
detach). For all devices we cared about the modem re-attached for us.
It looks like there's still a TODO for this in src/gprs.c
