> I have an emobile (Japanese provider) CDMA device that responds with +GCAP: +CGSM,+DS,+ES but not IS-707 and so only gets resolved as GSM by NM, but in reality it's a CDMA-only device and works fine when just dialed with pppd. What should I do in this situation? Also an earlier model from the same provider that was also CDMA failed to respond at all to the AT+GCAP (and subsequent) commands from nm-modem-probe. Is the device not following the spec or is NM too strict?

Emobile appears to be a GSM carrier, they appear to provide HSPA-based
3G services.  You may be confusing "CDMA" with W-CDMA.  W-CDMA (Wideband
CDMA) is the GSM-based 3G standard but shares a technological basis with
the CDMA2000 standards that we actually think of as CDMA.

What does your ppp dialup script contain?  That would help narrow the
issue down.
