What is an eSIM?
An e SIM is an electronic SIM card. As the name suggests, it will replace the physical, plastic SIM card all current smartphones use with a virtual embedded equivalent that cannot be removed.
One of the benefits of an eSIM is that it’s absolutely tiny, just a small fraction the size of a nanoSIM. And they’re only the size of my pinkie nail.
This is what makes it so well-suited to ultra-compact gadgets like watches, which simply don’t have the room for a normal SIM.
An eSIM is non-removable, and sits by other internal components. You don’t have to remove it, and it isn’t at risk of compromising any water resistance of a gadget’s shell.
With such an embedded standard, the idea is that you can switch to a new operator without having to insert a specific SIM card. It’s all done through software.
The same Apple Watch 3 can be used by Verizon, T-Mobile or Sprint in the US. Only EE currently offers the Apple Watch 3 in the UK, so network switching isn’t an issue.
