Hi Stuart,
I will try to upgrade the SIMCOM LTE module's firmware. Maybe it can solve the problem. Also I've got a related question: How can I connect to (mbim-mode) lte modem's AT interface. As I realized, I can not connect to an LTE device which has switched to mbim-mode under OpenBSD. Before mbim-mode I was able to connect to it via cu -l /dev/cuaU2 Thanks.
