Things you need to know about eSIM technology

With the advent of eSIM technology, it's time we say goodbye to our physical SIM card.

Perhaps it would be more reasonable to know what SIM is, before going into the eSIM technology.SIM, an acronym for "Subscriber Identity Module" , is basically an information container that authenticates your identity with a telecommunications service provider. In other words, the SIM card is a "bridge" between the user and the network. And without it, operators will not know that you are subscribing to their network and therefore do not allow you to use their mobile services.

Size is one of the great advantages of eSIM compared to traditional SIM types.

So, what's new in eSIM technology compared to traditional SIM cards?

What is eSIM?

According to Digital Trends, eSIM, just like its name is electronic SIM (electronic) or embedded SIM. However, unlike traditional SIM, eSIM is very small in size and soldered directly to the phone board.

With a traditional SIM card, you will have to change the SIM if you travel abroad and where you go does not support the network you are using, or you want to switch to another network. So, if SIM hours are integrated right on the phone, will you have no other way than to buy a new phone? Fortunately not. In fact, one of the advantages of eSIM technology is that it makes switching networks much easier than before. Instead of having to buy a new SIM card, you can proceed to change to another carrier right on your phone. Moreover, if you regularly use two (or more) SIMs at the same time, eSIM technology supports multiple accounts and switching between them is easy.

Those are the promises of GSM Alliance (GSMA). With eSIM, the phone will have a menu that allows users to switch networks and manage their accounts directly on their device. The Pixel 2 released by Google this year is one of the first phones to support eSIM technology, and you can download the eSIM management application on Google Play Store.

Google Pixel 2 is the first smartphone to support eSIM technology.

eSIM also has another advantage that helps devices become more compact. Although on the phone, this does not make much difference, but eSIM will be very useful for wrist devices. Apple Watch 3 smart watch has been integrated with eSIM, and it is part of the process of Apple transitioning to new technology to keep the size of the product still equivalent to previous generations but there are many improvements. proceed inside more.

When can I start using eSIM?

It may take some time before the potential of eSIM is acknowledged. Not only manufacturers have to create eSIM products but also operators must support this new technology. Not only the carriers in the US, but it would be great if operators all over the world embraced the technology. And for that to happen, perhaps we will have to wait a little longer.

Most likely, eSIM technology will also be available on laptops, when 5G and 4G-LTE technologies are deployed massively. At the present time, it is likely that the phone supporting eSIM will still have a traditional SIM slot, but with its potential and advantages, eSIM completely replaces the SIM card is only a matter of time.
