That depends on what the modem reports, and if the SIM has any overrides
for network names.  I'd need detailed modem-manager --debug output to
figure out if the modem is reporting the network wrong, or if
ModemManager is doing something wrong.

Can I get full NetworkManager output from the Gumstix?  The bits
included don't seem to show everything; NM will usually dump quite a bit
of information about what's going on to syslog's 'daemon' facility.
It'll show up in usually /var/log/messages or /var/log/daemon.log
depending on how syslog is configured on the device.

For the modem-manager end, if you can get into the device, stop NM and
modem-manager, then run 'modem-manager --debug' and then restart NM,
you'll get a lot of modem-manager spew that's useful for debugging
what's going on.
