Nah; this was just probably because you only had one TTY doing AT,
which is the one that got in connected state for PPP, and therefore
during the PPP connection MM tried to send some AT commands and
couldn't because no AT-capable TTY was left. Totally unrelated I'd
say; and we should silence those periodic messages that try to check
if connection is up or not when no unused AT-capable TTYs are
available.

Did you end up trying with uqmi/umbim, any difference?
