Looks like you've got two modems on the system, and the other one
(modem0) isn't happy:

ModemManager[4639]: <debug> [1737381559.914951] [modem0] couldn't check
if unlock required: Couldn't peek QMI port
ModemManager[4639]: <debug> [1737381559.915068] [modem0] retrying (22)
unlock required check

so what happens is that modem1 gets unlocked just fine, but because you
sent "-i any" MM will try to unlock both modems, and the other one
times out.

We could debug why modem0 isn't happy, or alternatively you could send
the PIN to modem1's SIM and it shouldn't take long.
