What is eSIM? Time to throw Plastic SIMs away

SIM stands for Subscriber Identification(or Identifier) Module which is present among us since 1991. Whether its mechanism in DTH Set Top Box or Credit/Debit Card, we are exponential times more focused on Telecom based chips. Why not? When we have such a huge telecom revolution going on in our country. 

Being accustomed to see and use nano, micro or mini sized SIM cards, you might be excited to now that its parent in 1991 for phones used to come in sizes of present day credit/debit cards. You might have seen DTH subscriber cards of the that size even today.

What is eSIM?

The e in eSIM doesn’t stand for electronic or electric as it’s already so. It stands for embedded Subscriber Identification ModuleBy the term itself we can understand that it’s inside or embedded in a system by default, which isn’t meant for physical touch. This concept is very recently brought into Apple Watch Series 3, Google Pixel phones and in Samsung Gear S3. These top tech. companies have already inaugurated this amazing technology in their device lineup. More manufacturers are about to follow them.

Why is it required? Can it replace our traditional plastic SIMs?

We had been using SIMs since the previous century and their hasn’t been much change in adaption other than sizes. Being a physical card made it prone to wear & tears leading to malfunctioning. Swapping between operators involved physical card change with possible chances of fine scratches during operation. However, the biggest reason among all these is the size. Even the smallest nano variant was too big to protect the chip which just stores IMEI numbers, few contacts and SMS. Use of SIM in smartwatches was thus a headache for OEMs. eSIM has saved few millimeters for them to organise more now. Shifting of SIMs between your eSIM enabled devices will be very flexible, safe and easy. Think of swapping your SIM from your smartphone to your smartwatch for a morning walk, within just 10 seconds.

Like consumers, operators will be benefitted by a remarkable margin. They no more will have to provide physical cards instead will just have to make encrypted IMEI numbers available to its subscribers for transferring it into their eSIM enable device. Getting a new connection will become very easy for every Indian. With Aadhaar based e-KYC and eSIM, consumers may not have to visit the store any more. All their procedure could be done through the operator’s online page very swiftly. Throughout this activity their will ultimately be zero use of plastic which is generally harmful for our environment.

Fun Fact:

If we already had eSIM devices before Jio’s launch, we could have made the largest eSIM adaption in the world ever. 😆 Well, but that could have reduced our queue record by one.. 😛 😉

With all these extraordinary advantages and the added one coupled with e-KYC makes it the best replacement for plastic SIMs present widely in today’s market.

Who will be the First Operator to launch eSIM in India? 

Internationally, operator like Vodafone already has eSIM services. Having experience, we can expect it to launch relatively before than others. Jio and Airtel will try their level best to expand their market share through this service.

Technically, more than operators, OEMs and manufacturers have to play the wider role. They will have to focus only on eSIM enabled devices in Indian market to make this a big success. 

We can expect manufacturers launching their eSIM devices coupled along with heavy operator offers. 🙂
