What specific card? Can you grab 'lsusb' and 'lsusb -v' output for me when the card is plugged in and (if needed) modeswitched into modem mode? Next, can you get some debug logging from ModemManager about why the modem fails to reconnect successfully when you pick the connection again from the menu? 1) service NetworkManager stop 2) killall -TERM modem-manager 3) modem-manager --debug 4) NM_PPP_DEBUG=1 NetworkManager --no-daemon (1 - 3 in one root terminal, and #4 in a second root terminal) then lets see what we get from both the modem-manager and NM debug output. Unfortunately it's not really possible to tell *why* the connection died without getting information directly from the baseband inside the modem, which probably means using the proprietary QCDM protocol to get that status info, and we haven't reverse-engineered the event/logging system there yet. But hopefully we get to that point... There could be any number of reasons why the call disconnected, from hard handoff to momentary signal strength dropoff to internal card errors.
