The SIM card is the main component of a cell phone without which it is not possible to use standard functions such as calling and texting other cell phones. It is known as the subscriber identity module and stores all the information of the user who is using the cell phone such as the mobile number, contacts, name, location and other lists such as call logs and messages. There are different versions of SIM cards that have been available over time. They differ in size and amount of data that can be stored on them. The earliest form of these smart cards was known as standard SIM card, later versions were known as mini cards which were smaller in size, and the next generation of these it was known as micro, while the latest versions are known as nano cards. There are only a few differences between the micro and nano versions, the main difference between them is of course the size, but there is no difference in the space provided. Micro is bigger in size while nano is smaller. Their sizes are normally different with a micro card having dimensions of 15 × 12 × 0.76 mm and a nano having a size of 12.3 × 8.8 × 0.67 mm. Micro is known as 3FF, which is the third generation of these chips, while nano is known as 4FF, which means the fourth generation of cellular chips. There are restrictions on nano versions because they cannot be converted to micro, on the other hand, micro cards can be cut and turned into nano cards efficiently, which helps a lot when the person wants to change their phone or move towards a new technology. Nano chips can be turned into micro chips with the help of separate objects such as adapters. Most companies are moving towards nanotechnology now, while micro technology could not last longer due to the rapid development that is taking place in the field of cellular networks. Another factor that distinguishes the two is that nanotechnology can last even less time than micro due to the introduction of integrated cards. The thickness of the micro cards was the same as that of the small and original SIM cards, but the thickness of the nano-SIMS has been reduced, which gives more space in the cell phone body for other functions. Nano chips can be turned into micro chips with the help of separate objects such as adapters. Most companies are moving towards nanotechnology now, while micro technology could not last longer due to the rapid development that is taking place in the field of cellular networks.

Definition of Micro SIM

These calling cards are considered the third generation of chips used in mobile phones. Due to the larger slots that were needed in the body of the phone, Apple decided to create another version of chips after the original and mini cards. There was a big difference from previous versions, the length of the card was shortened by almost 10mm from 25mm to 15mm, while the width was shortened from 15mm to 12mm, making it suitable for phones. newer mobiles. The thickness remained the same because more thought was put into creating more space. This SIM card was first introduced in the iPhone 4 and was first used in 2010, although they were developed in 2003.

Definition of Nano SIM

With the rapid changes in the world of mobile phone technology and the introduction of new functions in a short time, it was only a matter of time before an even smaller version of SIM cards would be introduced. There was a marked difference from micro cards as the length of the card was reduced from 15mm to 12.3mm, there were changes in width which decreased from 12mm to 8.8mm. For the first time, the thickness was also reduced from 0.76mm to 0.67mm, this was done to accommodate the iPhone 5, which had a sleeker design and required depth to be reduced alongside other sizes. There were many issues that people who wanted to upgrade their version from 4 to 5 faced because the slot sizes were changed. Therefore, the cards had to be cut to make them nano,

Differences in a nutshell

1. Micro cards are bigger than Nano cards
2. The micro cards are the same thickness as the originals and mini slots, but in nano, the thickness was reduced for the first time.
3. The size of a micro card is 15 × 12 × 0.76mm, while the nano comes in a size of 12.3 × 8.8 × 0.67mm.
4. Micro SIMS can be converted to Nano SIMS by hand, but nano cannot be converted to micro cards.
5. To save the nano card to micro, an adapter is required, while no such tool is needed to turn it upside down.
6. Micro cards led to the origin of nano chips, while nano cards resulted in the manufacture of embedded chips.
7. They both have different sizes but can store the same amount of memory between them.
8. The micro card is known as 3FF, while the Nano card is known as 4FF.

Final Thought

In the last decade, mobile phones have become an important part of human life. Therefore, it is essential to have an idea of ​​what components are constantly changing and the SIM is an important part for anyone who uses the phone. Overall, this article explains the difference and provides clarity on the two types of cards that are available.
