Information on Simlock

SIMlock is used by GSM network operators to restrict the operation of a mobile phone. SIMlock may be used to:

  • prevent the GSM mobile phone from operating with a different subscriber identity module (SIM) from the one supplied,
  • prevent a subscriber identity module from a different network operator from being used in the phone, or
  • restrict the services that are available using the mobile phone.

    •      Preventing the GSM mobile phone from operating with a different subscriber identity module (SIM) is a useful protection against theft. A stolen mobile phone with SIMlock cannot easily be sold, unless the thief is able to unlock it, that is, remove the SIMlock.
