I purchased an Ericsson F5521gw (Lenovo part 60Y3279) so that my Lenovo T520
could connect to China Unicom for internet access during a stay in China.
Unfortunately, it tends to fail every 4 to 8 hours with the following printed
to the system log:

Posts on the Lenovo forums suggest that this can be resolved by updating the
firmware:

Unfortunately, the official firmware updater only runs on Windows and I am
unable to find a way to update the firmware from Linux. I also cannot find any
hardware documentation. Does anyone have any suggestions?

Probably a better discussion for the ModemManager list (since that's
what you're using) but here goes...
As far as I know, there is no way to do this from Linux unless you
install Windows into a VM and use USB passthrough to allow the VM direct
access to the Ericsson device's USB interfaces.
I'm not sure what version of NetworkManager you're running, but NM
0.9.10+ have WWAN autoconnect support which will reconnect periodically
on failure. That coupled with setting your openvpn VPN connection as a
"secondary connection" to the WWAN should ensure that the VPN is always
up when the WWAN is up. That would be a good workaround if you cannot
find a way to update the firmware.
nmcli con mod "China Unicom" connection.autoconnect yes
nmcli con
<find your VPN connection's name or UUID>
nmcli con mod "China Unicom" +connection.secondaries <VPN name or UUID>
(this does require that your VPN passwords be stored
in /etc/NetworkManager/system-connections/, but rest assured they are
only accessible by root)
