A physical SIM can be transferred from a broken to a working phone. [34] The eSIM, which allows communications to be made and charged to the account-holder, cannot be removed if having the phone repaired, or lending it to someone. eSIM accounts must be deleted or transferred from a phone when it is sold or disposed.
A typical SIM card (mini-SIM with micro-SIM cutout) A SIM card or SIM (Subscriber Identity Module) is an integrated circuit (IC) intended to securely store an international mobile subscriber identity (IMSI) number and its related key, which are used to identify and authenticate subscribers on mobile telephone devices (such as mobile phones and laptops).

Both cards have been superseded by the UICC. An IMSI is usually presented as a 15-digit number but can be shorter.

SIM Application Toolkit (STK) is a standard of the GSM system which enables the subscriber identity module (SIM card) to initiate actions which can be used for various value-added services. [1] Similar standards exist for other network and card systems, with the USIM Application Toolkit (USAT) for USIMs used by newer-generation networks being ...
Dual SIM standby phones allow both SIMs to be accessed by using time multiplexing. When one SIM is in active use, for example on a call, the modem locks to it, leaving the other SIM unavailable.
