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.
