Thanks for it. Seem to be ok:

But of course, since the "simcom" driver don't exists yet, there is 
nothing after this:

ofonod[1019]: src/modem.c:set_modem_property() modem 0xfbcf8 property Modem
ofonod[1019]: src/modem.c:set_modem_property() modem 0xfbcf8 property Data
ofonod[1019]: src/modem.c:set_modem_property() modem 0xfbcf8 property GPS
ofonod[1019]: src/modem.c:ofono_modem_register() 0xfbcf8

What is the best driver to fork as a base for the simcom driver ?
