Many people continue to use older fashioned cell phones who then decide to migrate to an iPhone, and if you fall into that category (or are helping someone who does), a common migration step to go from an ancient flip phone or simpler cell phone to an iPhone is to import contacts from the SIM card of that older phone. This allows the user to bring their old contacts stored on a SIM card to the new iPhone easily. Aside from that initial migration, another scenario where you’d want to import SIM contacts is if you have an old phones SIM card laying around that had contacts on it that you’d like to migrate to the iPhone.
