An eSIM is an ’embedded’ or ‘electronic’ SIM card which is built into a mobile phone, smartphone or tablet device at the point of manufacture. The SIM stores all information that is necessary to identify and authenticate the mobile subscriber.
An eSIM will come in the form of an integrated SIM chip that cannot and need not be removed from a device. The eSIM is sometimes called an eUICC (embedded Universal Circuit Card). The information on the eSIM will be compliant and rewritable by all operators. The identification information can be updated over the air, to enable a change of operator. A new SIM will no longer be required, so hence no more having to deal with cutting SIM cards, or finding adapters.
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. 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. it is now easier to extend mobile connectivity to devices such as tablets, smart watches, fitness bands, portable health systems and various other devices.
