Always Use Mobile Data

Be warned that "ip route add default" does not persist across reboots. The defaults are normally handled by NetworkManager.

Thank you for that tip!

I've un-marked this as solved because of something else I've noticed...

Flushing the default IP routes and making a new one with wwan0's ip address works for only a limited time, even if the phone is not power cycled.

Something running in the background is noticing that I'm removing the wlan0 route as default and putting it back! I'm having a difficult time figuring out what that is. 

Does anyone know what service puts the wlan0 IP as a default route? I'd rather suppress that behavior than make a new service to continually monitor and clear the wlan0 default that keeps popping up.
