Update:
The workaround to get my modem back online was tedious and unreliable as it turns out. (Sometimes it restores the ability to make calls but sometimes the phone will not connect or sometimes it fails register with my cellular provider). I've been running modem firmware 01.003.01.003 since before Bookworm and Bookworm since the support for Mobian stable was reduced. It's been a good combination until now and I don't know what in a recent apt-get upgrade broke it.
Subsequent apt-get upgrades are not fixing it either so I restored my system from a backup image I'd made around September 1st and all is well again. I don't know why others are not reporting this problem but perhaps few users are using modem firmware 01.003.01.003 and the problem doesn't exist on previous firmware versions.
