Indeed, we could use for Huawei modems for instance the AT^SYSINFO 
command and retrieve the sys_mode field and parse it, I have found this 
in public Huawei specifications:

<sys_mode>: System mode. The values are as follows:
0 No service.
1 AMPS mode
2 CDMA mode
3 GSM/GPRS mode
4 HDR mode
5 WCDMA mode
8 CDMA/HDR HYBRID mode

Thus we can chose accordingly the drivers to create oFono atoms.

Kind regards,
Guillaume
