New Delhi. With the advancement of technology, the world is becoming more modern. Ever since the invention of mobile phones, many things have changed since then. Changes have been seen in the phone and other things in many ways. The SIM card is a small part of the mobile itself. Where does the phone work without it? But have you ever noticed that the SIM card is slightly cut from one side? Do you know why this happens? If not, then let us tell you.
There will be very few people who will know that why the SIM card is cut off after all. But even today there are many people who are not aware of this. In such a situation, today we will tell you why one corner of the SIM card is cut off. So let’s know.
How were the earlier SIM cards: Earlier SIM cards were the size of credit and bank cards. Sim cards with this size worked for years. These cards usually had the electrical contacts aligned so that a large card could be cut into a smaller size. The SIM card could be detached from the device and inserted into any device.
Here is the reason: When SIM cards were made for mobile phones, the design of the phone was quite simple. In the earlier phones, the SIM slot came with no cut. In such a situation, many times people had to face difficulties in installing the SIM card. It is said that the SIMs that came long ago were in the shape of a card. However, this is a long time ago. Not only this, people also had trouble in understanding whether they were putting the SIM straight or vice versa. Due to this there was a whole danger of spoiling the SIM. In view of this problem, the telecom companies changed the design of the SIM card itself.
Just because of this the corner of the SIM card was cut off. Then the SIM card slot was also changed accordingly. By doing this, people did not face any problem in inserting the SIM card. It was only this small reason that the companies cut the corner of the SIM and then made it a trend. The design of the SIM card tray in the smartphone also had a cut mark on one side. After this cut mark of tray and SIM card, people never faced any problem again.
