I have to work for 3 hours in a place with no wifi and no power outlet twice weekly. I physically connect my iphone to the MBA and it works great. The phone stays charged 100% and the laptop drains maybe 20% battery in 3 hours.
To everybody trying to justify apple not offering a wwan option.
On Thinkpad you can add the module later. It's a simple upgrade, open up the laptop and plug in the wwan module. The Thinkpad already comes with a sim tray. Though today presumably you would use an esim.
But hey you can pick a color for your macbook, so that's something.
Extra rant: the hardware quality of modern MacBook is fantastic. The keyboard sucks. The reflective screen sucks. The number of ports is ridiculously small. Soldered ssd and ram etc etc. Fantastic battery life. My thinkpad is a turd in comparison. But at least it doesn't bend when dropped. MacOS is horrible, Linux is the only thing I want. Sleep on modern PC is broken by design. A MacBook sleeping loses 1% of battery per day. A thinkpad loses 100%. Why can't we have nice things god dammit.
