That is my question. Does 7plus sim fit Apple iPhone 12 family.

IF it is a nano sim small one it should fit, but can confirm with consumer cellular if it fits or not as they provide the sim cards.

I use Consumer Cellular. Have 7plus. Buying one of the 12 I phones from Apple. Can I move 7plus sim to a 12?

Assuming you're still with Consumer Cellular and the sim card fits then yes.

Both use Nano-SIM card: Learn which size SIM card your iPhone or iPad uses - Apple Support

Their CS said take from current 7 and if I buy phone 12 from Apple just put current CC sim from 7 to 12. But I’m not convinced which is why asking on Apple Forum.

And why would you not be convinced?
