eSim Setting helps Android manage carrier profiles on an eSIM, allowing users to download and manage eSIM profiles through a user interface rather than dealing with removable SIM cards.

What's eSim?

eSIM is a global specification by the GSMA which enables remote SIM provisioning of any mobile device.eSIM now allows consumers to store multiple operator profiles on a device simultaneously, and switch between them remotely, though only one can be used at a time. The specification now extends to a wider range of devices, beyond the single companion device made possible with the first release. Manufacturers and operators can now enable consumers to select the operator of their choice and then securely download that operator’s SIM application to any device.Remote provisioning means much smaller devices can be supported. The first products have already come to market, and we can expect to see many further launches in 2018: it is now easier to extend mobile connectivity to devices such as tablets, smart watches, fitness bands, portable health systems and various other devices.eSIM is the only globally-backed remote SIM specification for consumer devices. This universal approach will grow the Internet of Things by allowing manufacturers to build a new range of products for global deployment based on this common embedded SIM architecture.
