Question

Can we get this ICCID number on featured phones?

Community Answer

It's already on your phone. Your iPhone's SIM number is technically called the ICCID, which stands for Integrated Circuit Card Identifier. It usually consists of 19 or 20 characters, and is both printed on your SIM card and stored inside it. The ICCID is a unique serial number and is specific to your SIM card.
