Quick answer: Want a separate number for work, a side business, dating, or travel without carrying two phones? Modern iPhones support dual SIM via eSIM, so you can add a second line digitally. Use a carrier eSIM plan for a "real" second line, a second-number app for the cheapest option, or a travel eSIM abroad. No hardware needed — but a few accessories help.

Pro tip — your iPhone likely already supports a second line via eSIM — no new phone needed.
iPhones from recent years run dual SIM (one physical + eSIM, or dual eSIM). You can keep your personal number and add a work or travel line digitally, choosing which line to use per call or text. Check Settings → Cellular to add a plan — most people don't realize they can do this already.
