Friends, we all use smartphone. But have you ever tried to know why one corner if sim card used by us is chopped? So, today i will tell you about it.

In 1991, when european communication launched its phone, it used sim card in form of chip which once inserted into mobile cant be removed. It was permanent. But because of change in technological development, too many changes were made in sim card as well. And today the sim card which we all use can easily be inserted into and removed from mobile. When sim card technology developed, sim was same in all four corners. Because all corners of sim were same, people had to face so many difficulties. People were unable to know from which side sim should be inserted. In order to solve this issue, sim card companies cut one corner of the sim card. This is the only reason why one corner of sim card is chopped.
