The term "Unlocking" in our case refers to removing the SIM CARD restrictions enforced by carriers on GSM mobile devices. SIM Locks may also be referred to as the Network Lock, Service Provider Lock or Subsidy Lock.
GSM Sim Unlocking originally started about 12-18 years ago in Europe, and required a technician with some electronics background, some cables (many different phones meant many different cables), some special tools and a steady hand in some cases. Normally this would void the warranty on any carrier device.
About 5 years ago, in 2005, some people began to realize that since the device has a LOCK, it must have a KEY, well they were absolutely correct. However, like a SAFE, each device has its own unique key, based on an algorithmic calculation and the device''s personal serial number (Imei or Esn).These keys are usually stored by the manufacturers and or by the carriers.
In America LG, Rim, HTC, Motorola, Nokia, Samsung and Sony Ericsson "pass the buck" back to the carrier for the subsidy codes, and the carrier sends the clients back to the manufacturers, in a vicious circle of agony. This makes it quite difficult for the consumer to unlock his/her phone.
