If you have an OPNsense firewall and a spare iPhone on a cell plan that allows tethering, you can use the phone as the firewall’s WAN connection to the cell network. This is handy in a long outage, for example a hurricane taking down your cable provider for more than a week. (Just an example.)

There are some hurdles, and it is best to configure all of this before you need it. During an outage it is hard to download the things you need.
