• SIM stands Subscriber Identity Module
• Most people do not know that once upon a time the SIM cards were
the size of credit cards, we called them just SIM
• Since then they have evolved to Mini, Micro and Nano SIMs
• They are evolving further into embedded SIM (eSIM) and integrated
SIM (iSIM)

8. What are eSIMs?
©3G4G
• eSIMs are physical SIMs that are soldered into the device and enable
storage and remote management of multiple network operator profiles
(remote SIM provisioning).

9. What are iSIMs?
©3G4G
• The integrated SIM (iSIM) moves the SIM from a separate chip into a
secure enclave alongside the application processor and cellular radio
on a purpose-built system on a chip (SoC).
