This page is used to setup 3G backup function. If you enable 3G backup, make sure your
WAN connection type is not in 3G mode. When the WAN connection is broken, router will
try to keep the connection with 3G mode. After WAN connection is recovered, router will
disconnect the 3G connection automatically.
