Description Aleksander Morgado 2014-02-27 09:01:13 UTC 
The Icera probing needs some fixes to correctly handle the Nokia 21M-02. It needs to extend the AT timeout of the command, plus add some retry logic as the device may initially return ERROR to the AT%IPSYS? command.

See: https://mail.gnome.org/archives/networkmanager-list/2014-February/msg00064.html
Comment 1 Tore Anderson 2014-02-28 15:41:31 UTC 
FWIW I've found a reliable way to make MM detect my modem as an Icera-based one:

pkill -STOP ModemManager
<plug in modem, wait for usb_modeswitch and then for it to settle>
pkill -CONT ModemManager

That suggests to me that retries and extended timeouts will do the trick.

Yeah, I had the same issue, if the modem is plugged in before MM runs, then it all works.  Hotplugging the modem while MM is running fails...  I'm now able to reproduce Tore's issue locally with my 21M.
