Rules related to SIM unlocking and efforts of each company

　Some electronics retailers and online shops handle SIM -free iPhone and Android smartphones (smartphones). In addition, the smartphone terminal released by telecommunications carriers (carriers) after October 1, 2021 is prohibited from SIM locks, and if you purchase a new smartphone from the previous carrier, you must continue to use the carrier. "Binding" has virtually disappeared. UQ Mobile, which handles iPhone released before the switching date, such as "iPhone SE (2nd generation)" and "iPhone 12 mini", is au ID and numbers on a dedicated procedure page on a PC / smartphone to meet all specified conditions. You can unlock the SIM by logging in with a 4 -digit PIN and following the guide. Fees are free for online. The model that requires the SIM unlocking procedure is a smartphone released before September 30, 2001, a terminal purchased at UQ Mobile before September 2, 2001, and a terminal without a UQ mobile line contract. Locking requires IMEI information of the unique identification number of the terminal. Note that either pattern is not guaranteed for either pattern, using a terminal purchased from UQ Mobile on another company line, using a terminal purchased from another company on the UQ Mobile line. Also, except for the iPhone, it is important to note that the frequency band may not match the carrier (purchase terminal) and the carrier you want to use, and the communication performance may not be fully utilized. In actual use, depending on the model, the iPhone requires a profile installation / setting, and the Android device requires selection (or manual input) of the access point name (APN). If you do not need to install the profile, you can really use it simply by inserting a SIM card into the terminal, so even if a SIM lock is applied at the time of purchase, it should be used as a real SIM -free iPhone. According to materials on the Ministry of Internal Affairs and Communications SIM unlocking rules, MVNO companies have canceled the SIM lock settings from April 2010, NTT DOCOMO will be released on or later SoftBank after August 27, 2005, and SoftBank will be released on or later. It is said that it sells without setting SIM locks. Based on the guidelines of the Ministry of Internal Affairs and Communications, online will also start 24 hours on online SIM unlock procedures.
