After that save and close the file.

4. Type:

sudo /usr/sbin/usb_modeswitch -W -c /etc/usb_modeswitch.conf
Now modem should identify as ID 19d2:0031:

~$ lsusb
Bus 001 Device 002: ID 19d2:0031

5. That the device was recognized by Network Manager, type:

sudo gedit /usr/share/hal/fdi/information/20thirdparty/20-zte-mf626.fdi
In the file paste:

<!-- -*- SGML -*- -->
<deviceinfo version="0.2">
<device>
<!-- ZTE MF626 HSDPA USB Modem -->
<match key="@info.parent:usb.vendor_id" int="0x19d2">
<match key="@info.parent:usb.product_id" int="0x0031">
<match key="@info.parent:usb.interface.number" int="3">
<append key="modem.command_sets" type="strlist">GSM-07.07</append>
<append key="modem.command_sets" type="strlist">GSM-07.05</append>
<append key="info.capabilities" type="strlist">modem</append>
</match>
</match>
</match>
</device>
</deviceinfo>

Now you can connect using Network Manager.
