1- A SIM lock, a simlock lock, a network lock, a media lock or a grant lock (master
A SIM lock, a simlock lock, a network lock, a media lock or a grant lock (master) is a technical restriction built into GSM and CDMA mobile phones by mobile phone manufacturers for service providers so to limit the use of these phones to specific countries and / or networks
The reason that many SIM network providers lock their phones is that they offer discount phones to customers in exchange for a payment contract for using the network for a specified period, usually between one and one. three years. This business model allows the company to recover the cost of the phone during the term of the contract. These discounts are worth up to several hundred US dollars. If the phones were not locked, users can sign a contract with a company, get the phone at a reduced price, then stop paying the monthly bill (break the contract) and start using the phone on another network or even sell the phone for profit.
The SIM lock blocks this problem by prohibiting network switching (using a new SIM card). SIM lock is very common if subsidized phones are sold with prepaid contracts. It is important to note, however, that the technology associated with the phone must be compatible with the technology used by the network carrier. A GSM cell phone will only work with a GSM operator and will not work on a CDMA network provider. Similarly, a CDMA cellular phone will only work with a CDMA operator and will not work on a GSM network provider. ]. Note that newer high-end mobile phones (2016) are able to support CDMA and GSM technologies, allowing customers to use their mobile devices over n ' any network. Examples of these mobile devices are the Apple iPhone 7 and Samsung Galaxy S8 smartphones.
