What's in a Sim Card? by Aubrie

A SIM card (Subscriber Identity Module) is a rectangular memory
chip used in some cellular telephones. It holds personal identity
information such as: cell phone number, phone book, text messages,
and other data. The SIM card makes it easy to hold this data and
activates the phone. Most cell phones come with built-in memory and
the SIM card which can be thought of a memory card; stores limited
information.
A SIM card is very helpful. If for some reason your phone is not
working, you can slide it out of your phone and into another. You
cell phone carrier will bill you for the call even though you used
another phone. The same is possible if you upgrade your cell
phone.
To use a phone that accepts your SIM card, the other phone must be
from the same carrier or unlocked. Some phones are locked by
carriers so that SIM cards only used by that carrier can be used in
the phones they make. If you’re traveling across the country
or over seas, (if your headset is not locked) you can buy a SIM
card that will allow you to talk at minimal cost to. For example
you can purchase a prepaid SIM card or SIM cards made by overseas
carriers.
