After a little bit of searching, I am able to detect the 'Mobilelink HSUPA 7.2 Mbps Model ML27' USB modem, it is in this thread (3G USB Modem Not Working in 12.04). The product key 20a6:f00e is found by lsusb
and usb-devices
.
sudu do
nano /usr/bin/usbModemScript
and type
#!/bin/bash
echo 20a6 f00e > /sys/bus/usb-serial/drivers/option1/new_id
Then save and exit.
chmod +x /usr/bin/usbModemScript
nano /etc/udev/rules.d/option.rules
and type
ATTRS{idVendor}=="20a6", ATTRS{idProduct}=="f00e", RUN+="/usr/bin/usbModemScript"
ATTRS{idVendor}=="20a6", ATTRS{idProduct}=="f00e", RUN+="/sbin/modprobe option"
Then save and exit.
sudo reboot
After reboot, it can be detected by Network Manager. I add it in the Mobile Broadband, with the following setting:
Country: Indonesia

Plan: Volume-based
Number: *99#
Username: empty
Password: empty
APN: internet
Network ID: empty
Type: Any
