Quick Look at eSIM Technology
Definition and Benefits of the eSIM
An eSIM, or embedded SIM, is a digital SIM that allows activation of your cellular plan from the carrier without using a physical SIM card. An eSIM differs from the classic SIM card design; instead, it is embedded right into the motherboard of the device, which makes it flexible and efficient.
Key Benefits
- Convenience: Switching between different carriers becomes easy, and the change in the carrier profile is done electronically and not physically changing the SIM card.
- Flexibility: eSIM up to different profiles for use, e.g., traveling or business purposes, in one device at one time.
- Space Efficiency: It creates space that can be utilized for fitting other components or larger batteries in the device.
- Environmental Impact: In turn, creating less plastic and electron waste caused by handling physical SIM cards.
Difference between eSIM and Physical SIM
An eSIM and a physical SIM basically do the same thing; they both connect your phone with cellular services. But fundamentally, they are differentiated by their form and function.
Physical SIM
- Removable: A SIM card is a removable piece that can be placed out and placed into a device physically.
- Single Profile: It means that generally it holds the profile of only one carrier at any time.
- Dependent on Physical Slot: Requires a SIM card slot supporting.
eSIM
- Embedded into the device: Thus, there wouldn’t be any physical slot of eSIM.
- Multiple Profiles: It can carry many carrier profiles and switch between them.
- Digital Activation: It can be activated using QR codes or through the help of carrier apps. No physical SIM card is required for activation.
iPhone’s Compatibility with eSIM Technology
Apple has embedded eSIM technology innovation inside the device for all the iPhone series starting from the iPhone XS, XS Max, and XR in the year 2018, henceforth, for every new model.
iPhone Models Compatible with eSIM
