Using and Installing an eSIM
iSIM (integrated SIM) works in the same way as eSIM.
Inserting a physical chip is unnecessary as the SIM is integrated directly into the device.
The eSIM is a smaller version of the traditional SIM card and supports the same functionalities.
The difference is that an eSIM cannot be removed, as it is soldered directly to the smartphone's circuit board.
The iSIM takes it a step further.
They are even smaller and connect to an equally small modem. It is integrated into the phone's processor, known as SoC (system on a chip).
iSIMs have many advantages.
Firstly, because they are less than 1mm2, they can offer mobile networks to smaller electronic devices such as smartwatches. This also leaves room to incorporate more powerful batteries.
Additionally, iSIMs are much more secure.
Their position and size mean they are physically inaccessible. Additionally, being integrated into the processor provides iSIMs with an additional layer of authentication to enhance data protection.
Finally, using this technology helps reduce the costs associated with manufacturing the slots for traditional SIMs.
