SIM card

The original iPhone's SIM card slot shown as open, with ejected SIM card.

The SIM card is located in a slot at the top of the device. It can be ejected with a paperclip or a tool included with the iPhone 3G.[61] In most countries, the iPhone is usually sold with a SIM lock, which prevents the iPhone from being used on a different mobile network.
