One can also remove sim lock outside official service centers. The info about lock is saved in the phones memory. It could be removed by knowing where it saved. A special cable needs to be attached to the handset. Program sends unlocking signal to the phone. Some handsets require more difficult procedure. The memory chip has to be removed from the phone, the sector of the software, which is responsible for the SIM-Lock, has to be found and edited by the programmer.

They rare, because need to be updated all the time, due to nonstop developing phone models and GSM market.
