Traditionally, every smartphone comes with a SIM slot to accommodate a physical SIM card. That said, in recent years, major smartphone OEM’s like Apple and Google have started using eSIM in their smartphones.
An embedded-SIM often abbreviated as eSIM is a form of programmable SIM that is embedded directly into a device.
So here’s everything you need to know about eSIM and how does it differ from a physical sim card.

What is An eSim?
Whenever you buy a new smartphone, the first thing you do is install a SIM card. A typical SIM card allows users to connect to a cellular provider’s network and access voice-calling, video-calling, and internet services.
Similar to a standard SIM card, an eSim allows users to access all of the services mentioned above. However, unlike a SIM card, an eSim is embedded into a smartphone’s mainboard. An embedded Sim is compatible with every major carrier across the globe. Moreover, the process of activating an eSim is relatively simple.
Since an eSim is soldered to a circuit board it is more secure and reliable as compared to a normal SIM.
An eSim eliminates the need to physically transfer a SIM card while moving on to a new device, and it also comes in handy whenever you travel to a new location. Additionally, an eSim allows smartphone companies to maintain design consistency and make the smartphone thinner.
Differences Between An eSim And Standard Sim
As mentioned earlier, eSim isn’t a removable card. That said, similar to an NFC chip an eSim can easily use and store multiple profiles from different service providers. A normal SIM card might seem to be small but in terms of microscopic level smartphone hardware it’s size is big. Consequently, small eSim is much better than a standard SIM.
Presently, eSim is being used by companies as an alternative to dual-SIM. Another major advantage of using eSim instead of a regular SIM is that it makes the smartphone more resistant to water damage and hardware wear. Lastly, eSim also eliminates the need for finding adapters as tri-sized SIM cards are still mainstream.
Devices That Support eSim
Presently, eSim is a relatively new technology and it hasn’t become mainstream yet. In fact, many flagship smartphones like Samsung Galaxy S10 and OnePlus 7 Pro doesn’t offer eSim support. That said, there are still many devices that support eSim. So these are the smartphones and other computing devices that support eSim.
