# This script automate the setup of QMI supported wwan devices.
#
# Tested on following environment:
# * Lenovo ThinkPad X220 (4286-CTO)
# * Gentoo/Linux, Linux Kernel 3.9.6
# * NTT Docomo UIM card (Xi LTE SIM)
# * Sierra Wireless, Inc. Gobi 3000 wireless wan module
# (FRU 60Y3257, vendor and device id is 1199:9013)
# memo:
# I recommend to check if your wwan module works fine
# for your mobile broadband provider with Windows
# especially if you imported the device from other country.
# You may have to initialize your device for your region.
# * Required kernel config (other modules may be also required):
# - qmi_wwan (CONFIG_USB_NET_QMI_WWAN)
# - qcserial (CONFIG_USB_SERIAL_QUALCOMM)
# * Required settings:
# - you may have to create /etc/qmi-network.conf.
# My qmi-network.conf has only a line "APN=mopera.net".
#
# your wwan device name created by qmi_wwan kernel module
# check it with "ip a" or "ifconfig -a". it may be wwan0?
