phones to specific countries and/or networks. This is in contrast to a phone (retrospectively called <b>SIM-free</b> or <b>unlocked</b>) that does not impose any SIM restrictions. </p><p>Generally phones can be locked to accept only <a href="/wiki/Subscriber_Identity_Module" class="mw-redirect" title="Subscriber Identity Module">SIM</a> cards with certain <a href="/wiki/International_Mobile_Subscriber_Identity" class="mw-redirect" title="International Mobile Subscriber Identity">International Mobile Subscriber Identities</a> (IMSIs); IMSIs may be restricted by: </p> <ul><li>Mobile country code (MCC; e.g., will only work with SIM issued in one country)</li> <li>Mobile network code (MNC; e.g., <a href="/wiki/AT%26T_Mobility" title="AT&T Mobility">AT&T Mobility</a>, <a href="/wiki/T-Mobile_US" title="T-Mobile US">T-Mobile</a>, <a href="/wiki/Vodafone" title="Vodafone">Vodafone</a>, <a href="/wiki/Bell_Mobility" title="Bell Mobility">Bell Mobility</a> etc.)</li> <li>Mobile subscriber identification number (MSIN; i.e., only one SIM can be used with the phone)</li></ul> <p>Additionally, some phones, especially Nokia phones, are locked by group IDs (GIDs), restricting them to a single <a href="/wiki/Mobile_virtual_network_operator" title="Mobile virtual network operator">Mobile virtual network operator</a> (MVNO) of a certain operator. </p><p>Most mobile phones can be unlocked to work with any <a href="/wiki/GSM" title="GSM">GSM</a> network provider, but the phone may still display the original branding and may not support features of the new carrier. Besides the locking, phones may also have <a href="/wiki/Firmware" title="Firmware">firmware</a> installed on them which is specific to the network provider. For example, a Vodafone or Telstra branded phone in <a href="/wiki/Australia" title="Australia">Australia</a> will display the relevant logo and may only support features provided by that network (e.g. Vodafone Live!). This firmware is installed by the service provider and is separate from the locking mechanism. Most phones can be <i>unbranded</i> by <a href="/wiki/Flashing_(technology)" class="mw-redirect" title="Flashing (technology)">reflashing</a> a different firmware version, a procedure recommended for advanced users only. The reason many network providers SIM lock their phones is that they offer phones at a discount to customers in exchange for a <a href="/wiki/Contract" title="Contract">contract</a> to pay for the use of the network for a specified time period, usually between one and three years. This <a href="/wiki/Business_model" title="Business model">business model</a> allows the company to recoup the cost of the phone over the life of the contract. Such discounts are worth up to several hundred <a href="/wiki/United_States_dollar" title="United States dollar">US dollars</a>. If the phones were not locked, users might sign a contract with one company, get the discounted phone, then stop paying the monthly bill (thus breaking the contract) and start using the phone on another network or even sell the phone for a profit.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> SIM locking curbs this by prohibiting change of network (using a new SIM). </p><p>In some countries, SIM locking 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 being used by the network carrier. A GSM cell phone will only work with a GSM carrier and will not work on a CDMA network provider. Likewise, a CDMA cell phone will only work with a CDMA carrier and will not work on a GSM network provider.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> Note that newer (2013+) high end mobile phones are capable of supporting both CDMA and GSM technologies, allowing customers to use their mobile devices on any network. Examples of these mobile devices are the Apple <a href="/wiki/IPhone_5c" title="IPhone 5c">iPhone 5c</a>, 6 and newer, Motorola's G4, G5, X Pure, Samsung's Galaxy S6, S7, S8 smart phones, mostly phones based on a <a href="/wiki/Qualcomm_Snapdragon" title="Qualcomm Snapdragon">Qualcomm Snapdragon</a> chipset or radio. </p><p>In some jurisdictions, such as <a href="/wiki/Canada" title="Canada">Canada</a>,<sup id="cite_ref-crtc-simlockban_5-0" class="reference"><a href="#cite_note-crtc-simlockban-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> <a href="/wiki/Chile" title="Chile">Chile</a>,<sup id="cite_ref-Chile-ban_6-0" class="reference"><a href="#cite_note-Chile-ban-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> <a href="/wiki/China" title="China">China</a>, <a href="/wiki/Israel" title="Israel">Israel</a>,<sup id="cite_ref-Israel-ban_7-0" class="reference"><a href="#cite_note-Israel-ban-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> and <a href="/wiki/Singapore" title="Singapore">Singapore</a>,<sup id="cite_ref-Singapore-ban_8-0" class="reference"><a href="#cite_note-Singapore-ban-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup> it is illegal for providers to sell SIM locked devices.

Alternative mechanisms include software running on the handset or a computer attached to the handset, hardware devices that connect to the handset or <a href="/wiki/Over_The_Air_Programmable" class="mw-redirect" title="Over The Air Programmable">over-the-air</a> by the carrier. Usually the unlock process is permanent. The code required to remove all locks from a phone is referred to as the <i>master code</i>, <i>network code key</i>, or <i>multilock code</i>. If the phone is network locked it will typically display one of the following messages: SIM network PIN blocked, Enter lock PIN. </p><p>There can also be multiple levels of locks placed on the phone by networks, which block the use of other networks' SIM cards. These are usually referred to as "Network Control Key" (NCK) and "Service Provider Control Key" (SPCK), additionally, a Regional lock exists which is specific to Europe and it is called "Region Control Key" (RGCK). </p><p>These locks can be removed using the corresponding unlock codes, which are unique to each phone depending on its IMEI.<sup id="cite_ref-10" class="reference"><a href="#cite_note-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup> </p><p>Typically, a locked handset will display a message if a restricted SIM is used, requesting the unlock code. On recent phone models running Android software, the phone will display a message saying “SIM network unlock PIN” or “Enter Network Lock Control Key” if network locked. Windows phones will display the message, “This SIM card can only be used on specific networks. Contact your customer service center for the unlock code”. Other handsets may display different messages such as "Enter special code" or "Enter unlocking code," or in some cases the handset will simply display a message stating that it is locked. Once a valid code is entered, the handset will display "Network unlocked” or “Network unlock successful”. </p><p>The unlock code is verified by the handset and is generated by the manufacturer, typically by an algorithm such as a one way <a href="/wiki/Hash_function" title="Hash function">hash</a> or <a href="/wiki/Trapdoor_function" title="Trapdoor function">trapdoor function</a>. Sometimes big telecom providers change the original factory unlock codes as an extra layer of security against unlocking services. For various big brands such as Samsung and Motorola there is no algorithm but just a random code generator where the unlock codes are programmed in the phone itself and then saved in a big database managed by the manufacturer. For the other brands where the unlock codes are still based on algorithms those are based on the <a href="/wiki/IMEI" class="mw-redirect" title="IMEI">IMEI</a> number and the MCC code and have been <a href="/wiki/Reverse-engineered" class="mw-redirect" title="Reverse-engineered">reverse-engineered</a>, stolen or leaked. Some handsets can be unlocked using software that generates an unlock code from an IMEI number and country and operator details using the algorithm specific to the handset. Other manufacturers have taken a more cautious approach, and embed a <a href="/wiki/Random" class="mw-redirect" title="Random">random</a> number in the handset's firmware that is retained by the manufacturer and the network on whose behalf the lock was applied. These handsets can still be unlocked by online services that have access to either inside people with the manufacturer or with the telecom networks, or they need to be connected to the computer with a cable where specific software will bypass the security and SIM-unlock the phone. Sometimes this is done by advanced calculations to bypass the security the official way and other times using exploits or overwriting parts of the firmware where the lock status is kept, and often even recover a phone that is <a href="/wiki/Bricked" class="mw-redirect" title="Bricked">bricked</a> or completely damaged in the software sense. </p><p>Most handsets have security measures built into their firmware that protects them from repeated attempts to guess the unlock code. After entering more than a certain number of incorrect codes the phone becomes <i>frozen</i>. This is a state where the phone will display a security message that the phone needs a service. Older phones could no longer be used at all at this point, however modern smartphones often keep working with the original SIM but require extra work to then unlock them correctly. In extreme situations physical access to internal hardware via in-circuit debugging may be utilised (for example, via <a href="/wiki/JTAG" title="JTAG">JTAG</a> headers on a circuit board). Such access may be required to modify initialization software used for <a href="/wiki/Booting" title="Booting">booting</a>. </p> <div class="mw-heading mw-heading3"><h3 id="Hardlocked_phones">Hardlocked phones</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=SIM_lock&action=edit&section=2" title="Edit section: Hardlocked phones"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>A hardlocked phone is one in which a telecom provider has modified the firmware on the phone to make it impossible to manually enter the unlock codes in any way. The only solution to SIM-unlock such a phone is to change the firmware to a firmware which has not been modified by any telecom provider, a so-called "unbranded firmware". </p> <div class="mw-heading mw-heading3"><h3 id="Economics">Economics</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=SIM_lock&action=edit&section=3" title="Edit section: Economics"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Handset manufacturers have economic incentives both to strengthen SIM lock security (which placates network providers and enables exclusivity deals) and to weaken it (broadening a handset's appeal to customers who are not interested in the service provider that offers it). Also, making it too difficult to unlock a handset might make it less appealing to network service providers who have a legal obligation to provide unlock codes for certain handsets or in certain countries. </p><p>In some cases, a SIM-locked handset is sold at a substantially lower price than an unlocked one, because the service provider expects income through its service. SIM locks are employed on cheaper (<a href="/wiki/Prepaid_mobile_phone" title="Prepaid mobile phone">pay-as-you-go</a>) handsets, while discounts on more expensive handsets require a subscription that provides guaranteed income. Unlocked handsets have a higher market value, even more so if they are debranded. <a href="/w/index.php?title=Debranding_(phone)&action=edit&redlink=1" class="new" title="Debranding (phone) (page does not exist)">Debranding</a> involves reflashing or replacing the firmware to remove the operator logo or any limitations or customizations that have been imposed on the handset by the operator, and is usually accomplished with software designed for a particular handset model, however, most smart-phones can be debranded and unlocked solely with the use of special software. </p><p>The main reason to unlock a handset is to be able to use it with a different SIM card. Consumers may wish to continue using their previous provider with a new handset or when traveling abroad they may wish to connect to a foreign network with a <a href="/wiki/Prepaid_telephone_calls" class="mw-redirect" title="Prepaid telephone calls">prepaid subscription</a>. </p><p>Nevertheless, the fundamental principle of GSM and its successors, is open interfaces which encourage competition among multiple vendors. This is the reason a mobile phone is, in fact, a combination of a phone and the subscriber identity module (SIM). Locking the phone to a network is not much different from having the SIM built into the mobile phone. Network operators in many industrialized countries are not bound by law to give the phone unlocking code to subscribers even after the expiry of the contract period. </p> <div class="mw-heading mw-heading3"><h3 id="Box_breaking">Box breaking</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=SIM_lock&action=edit&section=4" title="Edit section: Box breaking"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <style data-mw-deduplicate="TemplateStyles:r1236090951">.mw-parser-output .hatnote{font-style:italic}.mw-parser-output div.hatnote{padding-left:1.6em;margin-bottom:0.5em}.mw-parser-output .hatnote i{font-style:normal}.mw-parser-output .hatnote+link+.hatnote{margin-top:-0.5em}@media print{body.ns-0 .mw-parser-output .hatnote{display:none!important}}</style><div role="note" class="hatnote navigation-not-searchable">Main article: <a href="/wiki/Box_breaker" title="Box breaker">Box breaker</a></div> <p>A practice known as <i>box breaking</i> is common<sup id="cite_ref-11" class="reference"><a href="#cite_note-11"><span class="cite-bracket">[</span>11<span class="cite-bracket">]</span></a></sup> in the <a href="/wiki/United_Kingdom" title="United Kingdom">United Kingdom</a> and other markets.
