Hello OpenBSD,
I am experiencing a peculiar issue with a device in which I use a Sierra
Wireless EM7455(*) LTE module that I have converted to MBIM mode. I have
also disabled umsm by entering config -e -f /bsd.
Most of the time, the umb status on my device appears as *"SIM not inserted
PIN required,"* even though a SIM card is physically inserted. The only
scenario in which I achieve success is after rebooting the device. However,
rebooting is not a guaranteed solution—sometimes, it takes 4-5 consecutive
reboots before umb0 becomes functional.
How can I debug this issue?
For further context, I have also swapped out the LTE module with another
unit, yet I observe the same behavior across 5-6 different devices of the
same make and model.
*P.S.* The device has a single LTE module but dual SIM slots.
(*)

Also dmesg is attached via this email.
Thanks in advance.
