Embodiment Construction
[0042] In order to make the object, technical solution and effect of the present invention clearer and clearer, the present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0043] SIM Lock is a lock for the relationship between the mobile phone and the card, so it is also called SIM-ME Lock. Used to bind the relationship between the mobile phone and the card. Only certain types of cards can be used in a mobile phone. The main function of SIM Lock is to ensure the interests of operators. Through SIM Lock, it can be realized that the mobile phone can only use the card of the fixed operator. In this way, the interests of operators can be guaranteed when selling customized machines.
[0044] Along with the development of mobile communication and the continuous impr...

The invention discloses a method and a device for automatically adaptively locking SIM data, a mobile terminal and a storage medium. The method comprises the following steps of: detecting startup initialization of a mobile phone, and judging whether an SIM card is inserted for the first time; when the mobile phone is judged to be inserted into the IM card for the first time, acquiring data of the SIM card inserted for the first time, and storing the data as SIM LOCK card locking data; when it is judged that the mobile phone is not inserted into the SIM card for the first time and data of the currently inserted SIM card is the same as card locking data of the SIM LOCK inserted for the first time, it is judged that the currently inserted SIM card is a legal card, and the current SIM card is controlled to be normally used; and when the data of the currently inserted SIM card is different from the card locking data of the SIM LOCK inserted for the first time, the mobile phone is locked and cannot be used, and the SIM LOCK data can be automatically matched according to the SIM card put on the market of the mobile phone, so that redevelopment and rewriting of mobile phone software are avoided, and the development and production cost of the mobile phone is saved.
Description
technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a method and device for automatically adapting and locking SIM data, a mobile terminal and a storage medium. Background technique [0002] Along with the development of mobile communication and the continuous improvement of people's living standards, the use of various mobile terminals such as mobile phones is becoming more and more popular, and mobile phones have become an indispensable communication tool in people's lives. [0003] With the globalization of business, more manufacturers and operators will launch their mobile phone products in different regions of the world. Operators use different SIM card data in different countries and regions, so even the same operator has different SIMLOCK data in different countries. [0004] But the mobile phone manufacturer in the prior art does not necessarily know the specific country and the specific operator that the...
