Well, within the past few years we’ve detected a great deal regarding eSIM (embedded SIM). It all started with the launch of Google Pixel 2 and Pixel 2 XL once the search giant Google talked regarding the eSIM Support. So, what’s the eSIM technology and how it works?
You might have already heard about the rumor that smartphones can now not need SIM cards to connect with cellular networks in the future. So, to some extent, that foresight is about to be true. The eSIM technology might prevent from getting a new SIM card every time you move to a different carrier.
The technology may look complicated, however, this is often something remarkable. So, let’s explore more regarding the new eSIM and the way it works.
What is eSIM?
eSIM is an entirely new technology that can save you from getting a brand new SIM card each time you port your number to a different carrier. Even, GSMA has started generalizing the use of eSIM (embedded Subscriber Identity Module). The devices or smartphones that come with eSIM support can feature an internal SIM card that will be attached to the motherboard.
The best thing regarding eSIM is that the inner SIM card that’s attached to the motherboard will connect to the networks of multiple carriers. This technology eliminates the necessity for a Physical SIM card. However, the concept of eSIM isn’t new, GSMA had been testing the abilities of the software-based SIM cards from the year 2010.
eSIM features the same electrical interface that you simply can realize on micro, nano, or regular cards. the primary version of the eSIM specs was restricted to Smartwatches, fitness trackers, tablets. However, the second version of eSIM brought support for pretty much all consumer devices, as well as phones.
What’s new with eSIM?
As we’ve mentioned above, the second version of eSIM brought support for smartphones. The phone with eSIM support will store multiple carrier profiles promptly. However, you’ll only use one at a time, and the Carriers must use Remote SIM provisioning to tack the embedded SIM over the air.
Another best thing regarding eSIM is that the devices will share the same number and web plans. for instance, Apple Watch Series three has the eSIM support, and it will use the same mobile number as your iPhone.
Not solely number, however, you’ll also take advantage of the cellular network if you’re willing to pay some extra fee.
So, if eSIM may be very helpful for the carriers, manufacturers, and customers as a result of it’ll reduce the difficulty of maintaining multiple SIM cards. Not solely that, however, the same technology might facilitate carriers to switch the data on eSIM according to their need.
