What is a SIM lock
SIM lock:
A sim-lock, Network-Lock, carrier-lock, imei lock or (MASTER) SUBSIDY lock is really a technical constraint built into CDMA and GSM phones by producers to be used by carrier networks to restrict the usage of these phones to a particular countries and/or networks. This is as opposed to a phone (retrospectively called SIM-free or unlocked) which doesn't enforce any SIM limitations.In the event the cell phones were not locked, users can sign an agreement with a particular provider, obtain the low priced phone, then quit paying the monthly bill (thus breaking the contract) and begin using the cellphone on another network or maybe sell the device for a profit. SIM locking curbs this by prohibiting a change of service (using a new SIM).
Unlocking Technology:
Usually, a locked mobile phone will display a message if a restricted SIM is used, requesting the unlock code. On recent phone models working on Android os software, the cellphone is going to show a message saying “SIM network unlock PIN” or “Enter Network Lock Control Key” if it is network locked. Windows phones are going to show the message, “This SIM card can only be used on specific networks. Contact your customer service center for the unlock code”. Some other devices could display specific messages such as "Enter special code" or "Enter unlocking code," or in some instances the handset will probably present a message stating that it is locked. When a valid code is entered, the handset displays "Network unlocked” or “Network unlock successful”.
Economics:
Mobile handset producers have financial incentives both to strengthen SIM lock security (which placates service companies and permits exclusivity deals) and to weaken it (expanding a phone's appeal to buyers that are not interested in the service provider that offers it). Additionally, making it too tough to unlock a device could make it less attractive to mobile phone network service providers that have a legal responsibility to offer unlock codes for certain devices or in selected countries.
Unlocking Services:
Plenty of businesses provide a on-line smartphone unlocking service . This service calls for all those that wish to unlock a mobile phone to supply their IMEI number to a service supplier and often they will also ask for the country and cellular network the phone is locked to, sometimes sent via email or entered on their website. The supplier then will supply (for a fee) a unlock code for the mobile phone handset. For a lot of manufacturers for instance Nokia and Samsung many services also supply special remote-unlocking software with guidance, where a cable is required to remove the SIM lock from home. Such suppliers may well email the unlocking code or software which will remotely unlock the unit. The cost for unlocking a phone will certainly vary based on the mobile phone network it is locked to and the smartphone model itself, as each unlock code is unique to each individual handset.
Unlocking Service Providers:
Disappointingly there are lots of scammers on line retailers working in the smartphone unlocking industry. As a consequence it pays to be sure you use a reputable service provider for these services.
