Transferring contacts

Hey, everyone!

I currently have an AT&T Cingular Flip IV. It uses a nano SIM and I have all my contacts saved on that SIM.

I also have an iPhone XR that was gifted to me. When I put the SIM in the iPhone, it didn't recognize any of my contacts from the SIM.

Is there any easy way to download the contacts from the SIM to my iPhone, without having to enter each one in manually?

Thanks!
