SIM lock:

A SIM lock, Network-Lock, carrier-lock, imei lock or (Master) subsidy lock serves as a technical limitation built into GSM and CDMA phones by manufacturers for use by providers to limit the usage of these phones to specific locations and/or networks. This is not like a phone (retrospectively called SIM-free or unlocked) that doesn't impose any SIM constraints.The reason why numerous carriers SIM lock their handsets is because they provide phones at a discount to customers in exchange for a contract to pay for using the network for a selected time period, usually between one and three years. This business model allows the company to recover the price of a phone across the life of the agreement. These kinds of discounts are worth close to a couple of hundred US dollars.

Unlocking Technology:

Typically, a locked mobile phone will display a message if a restricted SIM is used, requesting the unlock code. On new phone models running Android operating system software, the cell phone is going to display a message stating “SIM network unlock PIN” or “Enter Network Lock Control Key” if it is network locked. Windows phones are going to display the message, “This SIM card can only be used on specific networks. Contact your customer service center for the unlock code”. Alternative devices may possibly show assorted messages including "Enter special code" or "Enter unlocking code," or in some circumstances the phone will probably present a message stating it's locked. As soon as a valid code is typed in, the handset displays "Network unlocked” or “Network unlock successful”.


Handset producers have commercial incentives both to strengthen SIM lock security (which placates service companies and enables exclusivity discounts) and also to weaken it (expanding a device's appeal to customers who aren't interested in the service provider that offers it). Additionally, making it too tough to unlock a device could make it much less appealing to mobile phone network service providers who've a legal obligation to supply unlock codes for some devices or in specific countries.

This service calls for all those whom wish to unlock a mobile phone to give their IMEI number to a unlocking company and quite often they will also require the country and network the phone is locked to, sometimes sent through email or entered on their website.

For a lot of makes such as Nokia and Samsung several services additionally deliver special remote-unlocking software with guidance, when a cable is necessary to remove the SIM lock at home.
