eSIM technology comes to the attention in this much more technically advanced stage. Do you know what it is? As we all know; connectivity is one of the most important things in the world now. Everything in the tech world connects with each other. When we talk about connectivity first thing comes to our mind is connecting via Wi-Fi or Bluetooth. But, when we consider our mobile devices, they connect through a SIM. All of our smartphones, smartwatches, and even routers start working after we insert SIM cards. SIM card is the base of connectivity in these devices.
In the present world of technology, the use of a SIM card is facing various types of improvements. First, it was full-size SIM card then the devices became smaller and to match with that, SIM cards became smaller too by introducing mini SIMs. And after that much smaller micro SIMs came into the tech world. Now for most of the smartphones, we are using Nano SIMs. After reducing the size of the SIM cards gradually they have become to a stage of vanishing the physical SIM cards.
What is an eSIM?
The meaning of eSIM is “embedded SIM” card. Embedded SIM means when we buy the device there is a “build in” SIM inside the device. “eSIM” is not a SIM card physically. eSIM is a technology which is inside your phone. You don’t have to go to the shop to buy SIM cards anymore because there is a “build in SIM” inside your device. And you don’t have to remove your SIM card anymore and also you don’t need a SIM tray inside your device anymore. So, eSIM technology is much more advantageous for small devices such as smart watches because the space taken for the SIM card tray can reduce and we can build much more small smartwatches.
Further describing, it is a chip in your phone acts exactly like an NFC chip used in payment technologies such as Apple payment or Google Pay. You don’t have to change the eSIM as you do with other SIM cards.
To activate and handle the eSIM you should connect to a network or should contact a telecommunications operator. eSIM technology can’t access to all types of networks. In some phones, other than the eSIM, there is a physical SIM card slot also. When there is such condition, eSIM acts as the second SIM support.
You can rewrite the information on this kind of SIM card. This is an additional advantage. You just have to do is, give one phone call and change the operator.
