SIM lock

Abstract: The embodiment of the invention discloses a method for preventing illegal SIM LOCK unlocking, which comprises: receiving a checking message carrying international mobile subscriber identification code, network control password and unlocking request from a mobile terminal; detecting whether the international mobile subscriber identification code and network control password is legal, and whether the current state of the mobile terminal promises to unlock; when the international mobile subscriber identification code and network control password is legal, and the current state of the mobile terminal promises to unlock, and sending a checking passing message carrying network control password to the mobile terminal. At the same time, The embodiment of the invention further provides a system and equipment for preventing illegal SIM LOCK unlocking, In the scheme provided by the embodiment of the invention, when the mobile terminal is locked, the local side and network checking unlocking and relocking process to the mobile terminal, solves the problem that mobile terminal is recovered when NCK is lost, recovered or illegally obtained.

Abstract: A method is provided for verifying personalization for a mobile radio terminal having a detachable Subscriber identity module (SIM) card The method includes the step of storing verification mode setting information in the terminal pertaining to verification modes that include a normal and a forced verification mode The information is then accessed to determine whether the mode setting information pertains to the forced verification mode, when a predefined condition exists When the mode setting information is set to the forced verification mode, it is determined whether a SIM lock code stored in the mobile radio terminal is identical to a SIM lock code stored in the SIM card When the SIM lock codes are not identical, it is determined whether a password input by a user is identical to a password stored in the terminal Additionally, the method includes the step of blocking the terminal when the passwords are not identical The method may be performed at the request of the user, or upon power-on of a terminal, or when a SIM card is inserted into the powered terminal or replaced with a new one

Abstract: Today, Africa is undoubtedly the fastest growing telecommunications market globally with its mobile communications continuing to maintain a significant share of the total mobile communications market. At the outset, mobile services consumers in Africa did not have to register in a subscriber database and had the benefit of using a product that is simple, easy to purchase and provides a degree of anonymity for customers. However, in recent years concerns regarding the use of mobile communications for illegal purposes have led to several debates to curb these practices. Thus, the introduction of the directive by several African states to capture and store data of consumers of mobile communications to enhance national security and protect consumers.This work examines the intent behind the adoption of the Subscriber Identification Module (SIM) Card Registration Directive by several African nations; its implications within the telecommunications sector towards its aim of protecting consumers and enhancing state security. Finally, we attempt at augmenting the effectiveness of the directive in the telecommunications sector.

Abstract: Towards the ending of year 2009, the Nigerian Communications Regulator, Nigerian Communications Commission (NCC) in exercising the powers granted it under the Nigerian Communications Act (NCA) 2003 issued a directive that all new Subscriber Identity Module (SIM) cards must be registered before activation, to be followed by the subsequent registration of the SIM cards of existing SIM card holders at a later date. This directive coming from the NCC was borne out of the need to have a credible database of SIM card holders in Nigeria that will be used to identify (for possible prosecution) criminal actors who perpetrate criminal activities through the use of mobile phones by exploiting the anonymity of an unregistered SIM Card. This article seeks to identify and address the data protection and other issues that will arise in implementing the SIM card registration process.
