#IPHONE 14 ESIN VS SIM
Apple has removed physical SIM card slots from the new iPhone 14 series. Instead, these new handsets will feature a couple of eSIM modules, allowing you to connect to two networks simultaneously, but only by registering the integrated eSIM to your carriers.

What is an eSIM?
But so-called eSIMs are designed to supersede old-style physical SIMs (and, in case you’re wondering, the ‘e’ stands for embedded).

Instead of being a removable plastic card inside your phone, an eSIM is a small chip embedded in your handset. You can’t remove it and put it in another phone.

The information on an eSIM is rewritable. This means you can change your network without removing your SIM and inserting a new one.

A time when eSIMS completely replace plastic SIMs is probably still quite some way off. At the moment eSIMs are more commonly used as the second SIM in a dual-SIM handset.
