A SIM card, also known as a subscriber identity module, is a smart card that stores data for GSM cellular telephone subscribers. Such data includes user identity, location and phone number, network authorization data, personal security keys, contact lists and stored text messages.
The short answer is, it's a Subscriber Identity Module, and it is a small circuit board which is placed in your iPhone (or any GSM phone) in order to identify it to your carrier. It's why you can swap SIMs in GSM phones and your phone number, voice, and data plans are swapped right along with it.On older devices, especially feature phones, it also stored things like text messages and contacts). The SIM card allows you to change cellular phones and keep the same user data. The SIM card is what lets your carrier know that you're the account holder of the iPhone using it.
