SMS over IMS probably, and on VZW it's going to use IPv6 too. In any case, SMS-over-IMS uses SIP, and unless we want to build a whole SIP client into ModemManager, we probably can't do SMS-over-IMS natively. Then again, that might not be so bad. > I can't seem to find anyone at Verizon able to give up useful > information regarding configuration/credentials to make it fly with > the MC7354/ModemManager setup we are developing with. > > Shifting to CDMA operation, the MM messaging API works fine with the > MC7354. With the 2G/3G network (either CDMA 1xRTT, EVDO, or GSM/UMTS) the SMS gets sent via the network layer instead of using IP, so it'll always work just using the modem. > If you think the MC74XX might improve our lot with respect to text > messaging we might make a shift. If all this is correct, then the MC7354 would work, but it'll require a lot more work including an IPv6-capable SIP client library for your apps.
