The iPhone 13 can use two SIMs at once: one physical nano-SIM and one eSIM, or two eSIMs on supported setups. It has only one physical SIM slot in the tray.

Quick Scoop

  • Physical SIM: 1 slot.
  • Active SIMs: up to 2 at the same time.
  • eSIM profiles stored: some sources say the phone can keep multiple eSIM profiles, but only two can be active together.

In plain terms, the iPhone 13 is a dual-SIM phone, not a dual-physical-SIM phone.
