SIM lock:

A sim lock, NETWORK-LOCK, CARRIER-LOCK, IMEI-Lock or (master) subsidy lock is actually a technical constraint built into GSM and CDMA phones by manufacturers for use by carriers to limit the use of these phones to particular countries and/or networks. This is in comparison with a phone (retrospectively called SIM-free or unlocked) that does not enforce any SIM limitations.

Unlocking Technology:

Typically, a locked smartphone will display a message if a restricted SIM is used, requesting the unlock code. On new phone models operating on Android operating system software, the mobile phone is going to display a message saying “SIM network unlock PIN” or “Enter Network Lock Control Key” if it is network locked. Windows phones should display the message, “This SIM card can only be used on specific networks. Contact your customer service center for the unlock code”. Alternative models could show specific messages for example , "Enter special code" or "Enter unlocking code," or in some cases the handset will simply display a message stating that it's locked. When a valid code is entered, the mobile displays "Network unlocked” or “Network unlock successful”.


Most of the time a SIM-locked smartphone is available at a considerably cheaper cost than an unlocked one due to the fact the company plans income via its service. SIM locks are applied on more affordable (pay-as-you-go) devices, whilst deals on more costly handsets need a subscription that delivers guaranteed income. Unlocked handsets have a greater market value.

Unlocking Services:

A lot of organizations offer a remote unlocking service . This service requires those people whom need to unlock a device to provide their IMEI number to a service supplier and in most cases they will also request the country and network the mobile phone handset is locked to, frequently sent by email or entered on their web site. The organization will then supply (for a fee) the unlock code for the phone. For some manufacturers for instance Nokia and Samsung a variety of services additionally deliver special remote-unlocking software with guidance, when a cable connection is needed to remove the SIM lock at home. Such companies may well email the unlocking code or software that will remotely unlock the device. The price for unlocking a mobile phone may change depending on the network its locked to and the phone model itself, as every unlock code is unique to each unique handset.

Unlocking Service Providers:

Unfortunately there are a multitude of scammers web sites working in the smartphone IMEI unlocking industry. Consequently it is prudent to be sure you locate a reputable service provider for this service. Take the necessary precautions and investigate all prospective suppliers before committing to place an order. In the case of online suppliers, make certain they specify their registered business name and matching registration details (every genuine enterprise should be lawfully registered with the official governing bodies within their country of origin) and ensure they give a legitimate certified address and contact information on their website. Also make certain that any payments made are thru legitimate sources such as a recognised bank or financial institution using a debt or credit card, but do not ever make payment via a direct transfer since this offers no fiancial security.
