What’s an eSIM?
eSIM are Embedded Subscriber Identification Module. They are also physical chips but are embedded on to the board of the cellphone. These sims cannot be removed from the phones but can be modified through phone settings.
What is iSim?
iSIM is Integrated Subscriber Identification Module. iSIM is a not a physical sim but the functionalities of the SIM built into the architecture of the phone’s system-on-chip (SoC) or processor. iSIM works the same way as the eSIM without the separate hardware and enjoys all the benefits of eSIM.
