WHAT IS ESIM? | Every Thing You Need To Know About Embedded SIM | ARTECH

EMBEDDED SIM (E-SIM)

Every one knows about what is ESIM. But in this blog I try to answer some questions which I get into my mind when ESIM was introduced, so I thought every one should have basic knowledge about it. And we will discuss briefly about Esim.

Why ESIM Is Implemented?

We all have mobiles which supports 2 SIMS or in some cases one. Their is a simple reasons behind this is, first is, to increase the space. It means in normal smartphones company has to give a sim tray to put our sim. Because of sim tray, lot of space is wasted and it becomes one oh the reasons to build bulky smartphones. As we can see from past many years as technology is evolving as well as the components also become smaller in nano size.

So manufacturers always try to keel devices as smaller as they can and replace the old technology with latest alternates. In this case by removing sim tray, we get lot of space. Which helps in adding other usefull components, like increase battery size, improve the camera lens size etc. And one more thing is water resistant. If mobiles phones does not have any port, it will be helpful to get certified IP rating.

How does it works? 

The chip which we see on the traditional sim card is now integrated inside the processor. Every thing works similar as before, but only difference is we can't access and change the sim like past. 

How To Get It In India?

In India major telecom operators Airtel, VI and Jio does supports ESIM. You can consult your network operator and get a new connection or if you have old number, then you can easily change the number to ESIM. 

NOW POSITIVES & NEGATIVES

PROS :

We have already discussed the positives above. First, this is the future for sure. it is more efficient and effective too. Second, It helps to reduce the wastage of space in smartphones. Third, because of ESIM we don't have sim tray port, which means higher IP rating.

CONS : 

For now I noticed two major cons. First, it takes little bit extra efforts than normal sim while activation. Second, you definitely need professionals if you have any issues regarding to the network. With old sims, if incase we have any network issue or something related, just pop out the sim and put it back again, sorted. But now it is not that easy. You have go to the operator to resolve the issue.
