eSIM: Is the end of the SIM card approaching? The term eSIM is being heard more and more. But what exactly is it different from the normal SIM cards we all use in our phones? We will discover all this in this article.

What is eSIM:

The term “eSIM” refers to a new standard announced by the GSMA – the association that represents network operators around the world. An eSIM (Embedded Subscriber Identity Module) is an electronic SIM card, which will replace the physical plastic SIM card that all current smartphones use with an embedded virtual equivalent that cannot be deleted.

The benefits of eSIM:

The integration of the eSIM could be beneficial for smartphone manufacturers as well as for us customers. For customers, this would reduce the penalty each time change SIM card when changing environment or operator. How? Devices that support eSIM have an internal SIM card attached to their motherboard. As a result, our smartphones will not need a physical SIM card to connect to the cellular networks of different operators.

The information (network data carried by a standard SIM card) on an eSIM will be compliant or rewritable by all operators, which means that a user can switch from one operator to another when he wants to.

For manufacturers, this would save space inside the smartphone. Removing the slot for the SIM card frees up a lot of extra space inside a phone. This is also what makes it so well suited to ultra-compact gadgets like watches, which simply do not have room for a normal SIM card.

Which devices (smartphones & smartwatches) are equipped with an eSIM:

The GSMA began exploring the possibilities of embedded SIM cards as early as 2010. Samsung used the GSMA-compatible eSIM system on its Gear S2 Classic 3G launched in February 2016, while Apple used eSIM to add connectivity to the Apple. Watch Series 3, was announced in September 2017.

Google Pixel 2 smartphones can also use the integrated SIM card technology: eSIM. However, eSIM support on Google Pixel 2 phones is currently limited to Google Project Fi subscribers.

The brand new Acer laptop, the world’s thinnest computer, the Acer Swift 7 announced at CES 2018, also ships an eSIM.

It is sure that in the coming months, the more manufacturers will integrate this technology, it will remain that all mobile operators adopt this technology to end with the physical SIM card.
