echo " /etc/mbim-network.conf"

echo " 3) The APN to use should be configured in the profile, in the"

echo
echo " 4) Optional APN user/password strings may be given in the"

echo " 5) If APN user/password is specified, the authentication protocol"
echo " to use (one of PAP, CHAP or MSCHAPV2) must also be specified in"
echo " the following way:"
echo " APN_AUTH=protocol"
echo
echo " 6) If you want to instruct the mbim-network script to use the"
echo " mbim-proxy setup, you can do so by configuring the following line"
echo " in the profile:"
echo " PROXY=yes"
echo
echo " 7) Once the mbim-network script reports a successful connection"
echo " you still need to run a DHCP client on the associated WWAN network"
