What is a network 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 mobile devices by producers to be used by service providers to restrict the use of these phones to specific locations and/or networks. This is in comparison with a cell phone (retrospectively called SIM-free or unlocked) that does not impose any SIM constraints.SIM locking is extremely common if subsidized phones are sold with pre pay contracts. It is really important to note, however, that this technology linked with the cellphone has to be compatible with the systems used by the network carrier. A GSM cellular phone will only operate with a GSM carrier and is not going to function on a CDMA network. Equally, a CDMA phone is only going to work with a CDMA network and won't work on a GSM service. Keep in mind that more recent (2013 and newer) top end cellphones are equipped to support both CDMA and GSM technologies, enabling customers to utilize their mobiles on pretty much any network.
Unlocking Technology:
A smartphone can be unlocked simply by entering a code provided by the network operator. Different mechanisms consist of software running on the device or a computer attached to the handset, hardware devices that attach to the handset or over-the-air by the carrier. Typically the unlock procedure is permanent. The code required to do away with all locks from a cell phone is known as the master code, network code key, or multi-lock code. Generally if the phone is network locked it will generally display one of these messages: SIM network PIN blocked, Enter lock PIN.
Economics:
The primary reason to unlock a mobile phone is usually to be able to use it with another SIM card. Users might like to keep on using their smartphone but with a different service or when traveling in another country they may want to connect to a foreign network by using a pre pay subscription.
Unlocking Services:
Certain companies offer a imei smartphone unlocking service . This service requires those people that want to unlock a handset to give their IMEI number to a unlocking company and in most cases they will also need the country and network the handset is locked to, often sent by email or submitted on their website. The company will then supply (in return for a fee) an unlock code for the mobile phone handset.
Unlocking Service Providers:
Unfortunately there are a great deal of fraudulent online retailers working in the smart-phone imei unlocking industry. As a result it is prudent to be certain you find a reliable service provider for this service. Take the necessary precautions and investigate all prospective providers before choosing to place an order. In the case of on line providers, make certain they specify their genuine business name and associated registration information (all genuine business is required to be legally registered with the official authorities in their country of origin) and make sure they provide a genuine registered address and contact information on their web-site. Furthermore make sure that any payments made are via legitimate sources as in a recognised bank or financial institution using a debt or credit card, but never ever make payment via a direct transfer since this offers no fiancial security. To assist with the search for a trustworthy service provider, we've supplied a listing just below (and in no specific order) of a number of legitimate organisations currently offering such services.
