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?

Yup.  That tells the phone what stored APN to use, in this case APN #1.
Whatever that is; you can use AT+CGDCONT=? to get them I think.
