And the following is found in /var/log/syslog. It seems there are some problems with ModemManager.

udisksd[1798]: Mounted /dev/sr0 at /media/test/Mobile Partner on behalf of uid 1000
usb_modeswitch[2446]: usb_modeswitch: switched to 12d1:1506 on 2/6

ModemManager[768]:   Couldn't create modem for device at '/sys/devices/pci0000:00/0000:00:14.0/usb2/2-1': Failed to find primary AT port

Therefore I use the following script from Janhouse (Janis Jansons)
git clone https://github.com/Janhouse/4g-connect-linux
sudo  apt-get install dhcpcd

Modify 4g-connect-linux/huawei-4g-linux.pl, and ensure the following is correct:

my $device="/dev/ttyUSB0";
my $interface="wwan0";
my $apn="Aeroflex.com";

sudo ./huawei-4g-linux.pl
This script also get IP by dhcpcd.

Huawei 4g modem (E3276 and possibly others) script by Janhouse (Janis Jansons).

You can close this script now or you can keep it open to monitor the link quality.

Link quality:
> AT+CSQ
> +CSQ: 31,99
> OK
dhcpcd.sh: interface wwan0 has been configured with new IP=YOUR_IP_OF_WWAN0

Or you can get it manually.
To get IP
sudo dhcpcd wwan0
sudo dhclient wwan
To release:
sudo dhcpcd -k wwan0
sudo dhclient -r wwan0

/var/lib/dhcp/dhclient.leases

option routers 10.10.1.1;

The connection is setup if DHCP client get an IP.

Known issue: only work for the first time dongle plugged into system. wwan0 is missing at second re-plug. Need reboot.

(20150126) Sometime the usb function switch not work, sometimes it does.
Even if it does, the wwan0 is not identified.

(20150123) After tested several times, the dongle cannot get detected on my 14.04 any more even after reboot
(20150126) Now it can, but not stable. Sometimes works, sometimes not.:
