Sim card Cloning
Phone cloning is copying cellular identity from one to another
Types of sim cloning
->CDMA cloning
->GSM cloning
CDMA cloning:
code division multiple access (CDMA) mobile telephone cloning involves gaining access to the device's embedded file system /nvm/num directory via specialized software or placing a modified EEPROM into the target mobile telephone, allowing the electronic serial number (ESN) and/or mobile equipment identifier (MEID) of the mobile phone to be changed. To obtain the MEID of your phone, simply open your phone's dialer and type *#06# to get its MEID number. The ESN or MEID is typically transmitted to the cellular company's mobile telephone switching office(MTSO) in order to authenticate a device onto the mobile network. Modifying these, as well as the phone's prefered roaming list(PRL) and the mobile identification number, or MIN can pave the way for fraudulent calls, as the target telephone is now a clone of the telephone from which the original ESN and MIN data were obtained.
GSM cloning:
Cloning has been shown to be successful on CDMA, but rare on gSM. However, cloning of a GSM phone is achieved by cloning the SIM card contained within, but not necessarily any of the phone's internal data. GSM phones do not have ESN or MIN, only an international mobile station equipment identity(IMEI) number. There are various methods used to obtain the IMEI. The most common methods are to hack into the cellular company or to eavesdrop on the cellular network.

A GSM SIM card is copied by removing the SIM card and placing a device between the handset and the SIM card and allowing it to operate for a few minutes and extracting the Ki, or secret code. This is normally done with handsets that have the option of an "extended battery" by placing the normal size battery in the handset and the Ki in the now vacant extra space. This is done by allowing the device to log the interaction between the mobile telephone switching office and the handset.
