eSIM is an embedded or virtual SIM that is provided by a network provider and enabled for DATA, VOICE & SMS. It functions the way physical SIM works but the difference is the deployment of the eSIM into a Smartphone/tablet/laptop and other devices that support eSIM. It does not need any physical SIM insertion into your SIM compartment like the way a physical SIM is inserted physically into a device. It is installed (virtually inserted)/downloaded automatically into your smartphone/tablet/laptop by scanning a QR (Quick Response) Code we will provide you with via email attachment. You can also install and activate the eSIM through an Activation Code we will send to you via email attachment.
