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. Switch between them remotely, though only one can be used at a time. Manufacturers and operators can now enable consumers to select the operator of their choice. Then securely download that operator’s SIM application to any device.
How to activate eSIM
First, you require a Phone or a SmartWatch have an eSIM feature.
