An eSIM (embedded SIM) is a form of SIM card that is embedded directly into a device as software installed onto a eUICC chip. First released in March 2016, eSIM is a global specification by the GSMA that enables remote SIM provisioning ; end-users can change mobile network operators without the need to physically swap a SIM from the device.
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).
eUICC can refer to any implementation or application of the eUICC standards in an eSIM device. Each implementation of eUICC includes software code, a processor to emulate the software, non-volatile memory used to store the unique identifiers and cryptographic keys that are part of a SIM profile, and a bus interface to communicate the SIM profile to the mobile device. eUICC standards specify ...
The language that is used to describe these specification is a little confusing since eSIM is not a physical format (or "form factor" - the phrase that is used to describe the various SIM sizes). The eSIM describes the functionality in the SIM, not the physical size of the SIM - and there are eSIMs in many formats (2FF, 3FF, 4FF, MFF).
A key technical aspect of Mobile Number Portability (MNP) involves the routing of calls or mobile messages (SMS, MMS) to a number once it has been ported.Various call routing implementations exist globally, but the International and European best practice employs a central database (CDB) of ported numbers.

For a classic example for understanding the fundamental difference of TDMA and CDMA, imagine a cocktail party where couples are talking to each other in a single room. The room represents the available bandwidth: TDMA: A speaker takes turns talking to a listener. The speaker talks for a short time and then stops to let another couple talk.
This is mainly important for international mobile roaming. Outside North America, the IMSI is converted to the Mobile Global Title (MGT) format, standard E.214, which is similar to an E.164 number. E.214 provides a method to convert the IMSI into a number that can be used for routing to international SS7 switches.
