It looks like the modem is only registered on the 1xRTT network (ie,
CDMA 2.5G).  Can you grab some debug logs of ModemManager (eg, kill MM,
then re-run it with --debug) when this error occurs so we can see if MM
is trying to connect using the right bearer and whether it's connecting
at the right time?  (eg, it should be waiting a while for the modem to
find the network before trying to connect).

Thanks!
