Editing Esim (section)

= What the heck is an eSIM? =

An eSIM is kind of like a regular SIM but it’s designed to be reusable. If a regular SIM comes attached to an account, then you can think of an eSIM as a blank slate with more flexible account management.

In the future many devices will come with an eSIM chip already installed and all the customer will have to do is scan a QR code and the chip will take care of the rest [esim-overview].

The new eSIM chips mean less messing around with physical cards but they also make life easier for operators and manufacturers, too. For operators, eSIM gives them new remote provisioning capabilities to help with account management, and for device manufacturers it gives them the power to lock down devices, paving the way for IoT that “just works” [esim-spec].

In short: eSIM offers all these great new features over the old U/SIM cards. Of course, to support all that new functionality the GSMA (Global System for Mobile Communications Association) have had to make some changes to the way trust is represented in the mobile ecosystem. '''And what they’ve come up with is pretty darn impressive to say the least!'''
