Not mentioned in the article, but I'd also recommend force-setting DHCP Option 43 to "ANDROID_METERED" to let Android clients know you're on a metered connection (hotspot) instead of a normal landline-based WiFi network. [1] This inhibits some things like automatic updates.

I don't know of an equivalent for other OSes, unfortunately.

https://apple.stackexchange.com/questions/199163/how-does-io... seems to think it's in the wifi beacon itself for OS X.

No detection method appears to be present in Windows 10, it's all geared towards LTE modems integrated in the machine.

I really wish this had been standardised.

Windows 10 appears to support one of the newer standards for announcing su h details in beacon

"Microsoft has defined a vendor extension to the 802.11 protocol."

It also supports at the very least WiFi Alliance's Passpoint, based on 802.11u.

One can also use traffic shaping (iptables and tc) to dry up large downloads:

As anyone aware of even better solutions than this?

For macOS you need to use an app like TripMode [1] or Little Snitch [2].

Non unlimited data SIM cards are very uncommon in Austria where the writer of this article is from.
