GoKawiilGuide clarifies phones don't require shutdown for physical SIM card swaps
A tech explainer notes that most modern smartphones allow users to remove and replace physical SIM cards while powered on, without requiring a shutdown or airplane mode. The guide outlines the swap process—ejecting the tray, changing the card, and reinserting it—and notes dual-SIM phone owners should confirm which slot they're changing. It also contrasts physical SIM flexibility with eSIM, which uses QR codes or carrier apps for transfers but can only have a few profiles active simultaneously.
