What is a CARRIERLOCK
SIM lock:
A sim lock, NETWORK-LOCK, Carrier Lock, IMEI-Lock or (Master) SUBSIDY lock is actually a technical constraint built into CDMA and GSM mobile phone devices by producers for use by service providers to limit the usage of these phones to specific locations and/or networks. This is in contrast to a phone (retrospectively called SIM-free or unlocked) that doesn't enforce any SIM limitations.SIM locking is very common if subsidized devices are sold with pay as you go contracts. It is really important to note, however, that the technology accompanying with the cell phone has to be compatible with the system being utilized by the network carrier. A GSM cellular phone can only work with a GSM carrier and isn't going to function on a CDMA service. In a similar fashion, a CDMA mobile phone is only going to work with a CDMA network and is not going to operate on a GSM service. Be aware that more modern (2013 onwards) advanced cellphones are equipped to support both CDMA and GSM technologies, allowing customers to use their smartphones on any type of network.
Unlocking Technology:
A mobile can be unlocked by entering a code provided by the network operator. Alternative mechanisms consist of software running on the handset or a computer attached to the handset, hardware devices that attach to the phone or over-the-air by the provider. Usually the unlock procedure is permanent. The code needed to eliminate all locks from a phone is referred to as the master code, network code key, or multi-lock code. Generally if the device is carrier locked it will generally show one of the following messages: SIM network PIN blocked, Enter lock PIN.
Economics:
On many occasions a SIM-locked phone is sold at a substantially lower price than an unlocked one mainly because the service provider anticipates income thru its service. SIM locks are currently employed on more affordable (pay-as-you-go) mobile phones, despite the fact that deals on more pricey handsets demand a subscription that offers guaranteed income. Unlocked devices have a better market value.
Unlocking Services:
Certain organizations provide a unlocking service . This service requires those people that need to unlock a mobile phone to provide their IMEI number to a service supplier and in most cases they will also request the country and service provider the handset is locked to, often sent by email or submitted on their web-site. The company will then supply (in return for a fee) a unlock code for the mobile phone. For many manufacturers as in Nokia and Samsung several services also supply special remote-unlocking software with instructions, where a cable is necessary to remove the SIM lock from home. Such suppliers may well email the unlocking code or software that should remotely unlock the device. The price for unlocking a cell phone may vary according to the mobile phone network it's locked to and the device model itself, as each unlock code is unique to each individual handset.
Unlocking Service Providers:
Regrettably there are a huge number of scammers web sites operating in the smartphone carrier unlocking industry. Consequently it pays off to make sure you locate a trustworthy provider for these services. Take the necessary precautions and investigate any potential suppliers in advance of committing to place an order.
