Can i put my iphone 12 sim card in my iphone 4s

NO. The iPhone 4s is no longer usable as it still uses 3g and that has been sunset.
Even if the 4s was still supported, it takes a micro sim, which is a different size than the nano sim in your iPhone 12.
Because of the 3G shutdown, AT&T is only supporting iPhone 6 and newer.
These phones will still work on our network after we phase out 3G in February 2022 (att.com)
Even with a compatible phone, it must use the same size SIM card. You can put a smaller one in a bigger slot with an adapter, as the chip is used the same it is only the plastic part to fit so it lines up and doesn't move around.
How can we improve?
