Using SMS with MC7354 in the Verizon LTE network

[Reinhard Speyerer]

AFAIK it should not be required to implement a IMS client in
ModemManager for sending/receiving SMS in the Verizon LTE network at
least when either the MC7750 or the MC7354 with the VZW Gobi image is
used as both include an IMS client for SMS in their firmware.

If IMS registration has been successful according to the AT!GSTATUS?
output it should be possible to send a SMS via the internal IMS client
by using the ModemManager/libqmi equivalent of the Gobi API WMSRawSend
method with TLV 0x13 (SMSOnIMS) set to 1.

Due to the Verizon requirements for SMS over IMS the RawMessage passed to
WMSRawSend has to be in 3GPP2/CDMA2000 format even if LTE is used.
