An eSIM: Embedded SIM or Embedded Universal Integrated Circuit Card (eUICC) is a programmable SIM that can be embedded directly into the device.
With each passing second, the tech world comes up with something that blows our mind. Now, before knowing eSIM, there are few things to know about regular SIM Cards. SIM Card played a vital role in telecommunication industries for over 25 years. A physical SIM Card is an integrated circuit. It has an IMSI number and the network information. SIM cards are getting smaller over the years: Full-size SIM was the first type of SIM, and then it goes like this: Mini-SIM, Micro SIM, and last Nano SIM. Although, the functionality is totally independent of each size.
When we buy a SIM, it has an International Mobile Subscriber Identity i.e. IMSI. The telecom operator will activate our IMSI number and you'll see the phone is connected to the network.
An eSIM is an SMD component that is directly soldered to a circuit board during the manufacturing process, and it has the same electronics interface as 3FF, 2FF and full-size SIM Cards. Since 2010, the GSMA was thinking about the opportunities of a Software-based SIM. Later on in 2012, the European Commission introduced eCall based on the eUICC format in the emergency vehicle. And then Apple Inc integrated eSIM support in Apple Watch Series 3 and 2nd Generation iPad Pro. Back in the game, Google introduced eSIM in Pixel 2 to support the Project Fi services. Now, iPhone XS, iPhone XS Max, and iPhone XR using Dual SIM with a nano-SIM and an eSIM. If you need any kind of information on this article related topic click here: Energy Management System
