Well if you have seen the period of last one or two decade, then you must familiar with the SIM card. Don’t you? Almost everyone in today’s world uses the SIM card in their mobile devices. But soon that SIM card will be extinct and eSIM will take it’s place. So without any further ado, let’s get started.
The eSIM gives us an improved and more secure customer experience, better-designed devices, opens up new market opportunities for operators and enables entire new categories of connected devices.
What is the SIM?
The Subscriber Identity Module cards popularly known as SIM consists of a physical card containing the chip, store network-specific information used to authenticate and identify subscribers on a cellular network.
For the last 27 years we all are using SIM cards in our cell phones and smartphones but in 1991, the size of the SIM card was not as small as today’s card, but it was the size of a credit card. But now the size of the SIM card has dramatically reduced from a size of the credit card to a nano sim.
What is the eSIM?
The eSIMor Embedded SIM is formally known as embedded Universal Integrated Circuit Card (eUICC), is a 6 mm in length and 5 mm in width and is soldered onto a device’s motherboard at the point of manufacturing while having the same functionality as a removable SIM. It has M2M (Machine to Machine) and Remote Provisioning capabilities.
If you want to change operator or you’re traveling on holiday, you have to go to opt out a new SIM card but it’s all changing though. In the last few years, Apple introduced the Apple SIM for iPad, Google and Apple have included an eSIM as part of its new product launches.
Various advantages of the eSIM over physical SIM
Remote Provisioning capabilities within the eSIM standard provide us with an enhanced customer experience when activating and managing our cellphones. Through our mobile settings, we can select our operator and what plan we want and that’s it.
Note: In the US, AT&T, T-Mobile USA, and Verizon Wireless support eSIM. eSIMs will also be great for other devices like laptops and tablets, where seamless connectivity will become the norm.
An additional consumer benefit that we’ve heard discussed is that the eSIM should ensure future devices are cheaper to manufacture because there would no need to design any extra space or slot for the manufacturers. So the manufacturers can use that extra space for other purposes.
The future of eSIM
The eSIM is the future for the communication devices, but it will not happen in a quick, look down at your cellphones now it still has a physical SIM card. In the Google Pixel 2 and Google Pixel 2 XL the eSIM is currently only used by Google Project Fi and thus it has a physical nano-SIM card tray for all the other operators.
It will take some time for the manufacturers to include eSIM’s as standard SIM instead of a physical SIM slot in the cellphones as well as in the other smart devices like laptops, tablets etc.
