Only by accident, for about a week (that's definitely extended for me). We went on holiday to a remote Scottish island and stayed on a camp site that allegedly had WiFi: well, they did, but not working WiFi.. Oh well, I'd brought my 4G phone, and .. no signal. So a trip into the only town where I was told "only one carrier had a tower there", so I bought a PAYG SIM only to find it was the old-style full size SIM and no, they didn't have anything more modern.

So, a week without..

You can literally use a nano/micro SIM as a blueprint, and then just normal scissors to cut the SIM to shape. It's what I did the last time I needed to.
