GSM phones are associated with what’s called a SIM card, or Subscriber Identity Module. This card, about the size of a fingertip and the thickness of a piece of paperboard, carries an encrypted version of all the information needed to identify the wireless account to the network. On most GSM phones the SIM card is usually under the battery.
