My friend got this cdma ZTE usb modem this week and tested on KLIXs but he never manage to get this modem running, so here is the steps to make it work using usb_modeswitch :
First of all, we have to learn something by investigating the lsusb output at the time this modem was inserted into usb slot :
{code type=css}[root@jfklixs-domain SOURCES]# lsusb
Bus 001 Device 003: ID 0402:5602 ALi Corp. Video Camera Controller
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Now see what dmesg give us for more information :
{code type=css}scsi 2:0:0:0: CD-ROM ZTE USB Storage FFF1 2.31 PQ: 0 ANSI: 2
scsi 2:0:0:0: Attached scsi generic sg1 type 5

sr: Sense Key : No Sense [current]
sr: Add. Sense: No additional sense information

It’s not hard to know by investigating the dmesg output that this device has a flip flop device state that the usb device now acting as standard usb storage cdrom rather than a modem, so we must switch them unto a modem device by using usb_modeswitch.
Install usb_modeswitch package from synaptic, and add this at the end of /etc/usb_modeswitch.conf before running usb_modeswitch :
{code type=css}########################################################
# /etc/usb_modeswitch.conf
#
# Smart ZTE AC2726 (EVDO)

DefaultProduct= 0xfff5

Save it and now run the usb_modeswitch :
{code type=css}[root@jfklixs-domain SOURCES]# usb_modeswitch

The usb_modeswitch should flip up the usb storage device turns into usb modem, and this should be noted using lsusb which now show fff1 product code :
{code type=css}[root@jfklixs-domain SOURCES]# lsusb
Bus 001 Device 003: ID 0402:5602 ALi Corp. Video Camera Controller

Now modprobe and pickup the modem usbserial driver so it create the modem device node as ttyUSB0
{code type=css}[root@jfklixs-domain SOURCES]# modprobe usbserial vendor=0x19d2 product=0xfff1
[root@jfklixs-domain SOURCES]#{/code}
Check the corresponding created modem device node using dmesg again :
{code type=css}usbcore: registered new interface driver usbserial
usbserial: USB Serial support registered for generic
usbserial_generic 2-2:1.0: generic converter detected
usb 2-2: generic converter now attached to ttyUSB0

usbserial_generic 2-2:1.2: generic converter detected
usb 2-2: generic converter now attached to ttyUSB2
usbserial_generic 2-2:1.3: generic converter detected

Done, Now you could possibly create the modem connection setup and account setup using KPPP.
I create some small desktop script just to ease my friend so he has not to always type that command all over again each time he plugged the zte modem.
Oh btw, use this Init String command to avoid modem disconnecting problem if that bothers you :
{code type=css}ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0{/code}
somehow the modem connection using smart provider was perform well on my friend laptop, but not on mine, so I have to use that command init string to stay connected.
