Apple and Google devices have applied eSIM technology recently. However, what it is? Why do people keep talking about eSIM? Is it important for us?
According to Google Trends, the search rate of “eSIM” is becoming a popular keyword, a much higher listing than “Prepaid SIM” during September.
The eSIM/Embedded SIM, or as it’s more formally known, embedded Universal Integrated Circuit Card (eUICC), is smaller again at 6 mm in length and 5 mm in width and is soldered onto a device’s motherboard at the point of manufacturing while having the same functionality as a removable SIM.
The difference between a traditional SIM and eSIM is that eSIM operates a virtual SIM card. That means you can install it on your phone without the casing of a traditional SIM card. The eSIM is already installed on your device and you will never see it, even when you change your mobile network provider or plan.
Simply put, an eSIM is a feature concept for the way a SIM profile is managed. A traditional SIM is provisioned with a single profile which usually has 64KB or 128KB of memory. An eUICC can host multiple profiles and requires a minimum memory of 512KB.
Process for purchase of an eSIM
