This already happens with Nespresso coffee machines (they have an SIM that connects to the Internet, whether you want it or not). That day is already yesterday.
This coffee machine is equipped with M2M (Machine to Machine) techology which may be activated in due time with your agreement. Thanks to a SIM card already integrated in the machine, such network connections will offer new services (subject to further terms and conditions) to its customers and improve the after sales process by automatically communicating machine troubleshooting / diagnostics to our Customer Relationship Centre (depending on country requirements and specificities).

And if coffee pods don't come with always-online DRM yet, I'm honestly surprised at Nespresso's lack of dedication to this dystopia.
If so, then there would be hell to pay the first time if happened. If it works sans connection, then do what I've said elsewwhere and that's to cut or short out the antenna lead.
Removing the SIM may be deemed provocative by the manufacturer, if there's no signal reception then that's a different matter (the user can't be blamed).
I wonder if I can use it for mobile data.
All over, done permanently. Never another internet connection.
