Why is one corner of the SIM card cut?

SIM card is such a thing, which is used by a large number of people. Technology experts say that there is a special reason behind designing the SIM card in this way. One corner of the SIM card is cut so that it can fit properly in the phone. This makes it easy for people to understand whether they are inserting the SIM card straight or upside down. If the SIM card is inserted upside down, it will not work. This will prevent network in the mobile and there is also a risk of the SIM card getting damaged.

How does a SIM card work?

The full name of the SIM card is Subscriber Identity Module. Its job is to connect the mobile device to the cellular network. It stores the International Mobile Subscriber Identity (IMSI) number and the keys associated with it. With their help, the user of a mobile network is identified and authenticated. After being switched on, the mobile reads the data of the SIM card and passes it to the mobile network. After this process, the network verifies the identity of the user. This lets it know whether the user can access the network or not. For this reason, the SIM card of one company cannot connect to the network of another company.
