eSim is a new technology from GSM Alliance that seeks to face out the proprietary SIM cards used in cellular phones. But what does it entail and what’s in it for mobile subscribers?
What are eSims?
An eSim, which is the acronym of embedded Subscriber Identity Module (SIM), is a piece of technology that contains information that authenticates the mobile user’s identity to a network operator or carrier. Unlike the typical SIM cards, it is built into the phone’s mainboard to allow connectivity.
The embedded chip is compatible with multiple carriers, in spite of their network types. The design seeks to eradicate the hassle associated with changing carriers. For instance, it will allow users to switch to a new carrier or change SIMs by making a quick phone call to the operator. For those who prefer dual-SIM, this technology will allow you to create multiple accounts, which you can swap quite easily. The Apple Watch 3 and Google Pixel 2 are the first mobile devices that support the eSIM. However, the technology has been used in several other platforms such as car infotainment systems.
The Advantages of eSIMs
Phone manufacturers are most likely the first group to enjoy the benefits of eSIMs. Since it is inbuilt, there won’t be a need for SIM card slots thus giving manufacturers more flexibility regarding design. This might even help in the production of thinner phones. eSIMs can also be a lifesaver for frequent travellers who have to carry multiple phones or use different carriers to stay connected. By just making a quick call to the network provider, one will be able to swap SIMs across different continents.
Disadvantages of eSIMs
As mentioned earlier, changing your carrier will involve contacting your operator. This can be somewhat hectic for people who are used to simply pulling out a SIM card from the phone and replacing it with another almost instantly. There could also be a significant challenge during the adoption of eSIMs. It might take time for all major carriers globally to make the transition.
