SIM card
Is there an adapter to allow use of a SIM card in the Apple MacBook Air 6.2, early 2014?
MacBook Air 13″, macOS 11.6
That answer seems correct. But I am now trying to use Personal Hotspot. You need one device with a SIM card capable of using cellular data (my iPad) and then connecting the Mac Air to it through wifi. There are instructions in Apple Support.
