!!! Overview
[{$pagename}] ([MSISDN]) is the mapping of the [Phone Number] to the [SIM]/[UICC] card in a [Mobile Device]
[{$pagename}] together with [IMSI] are two important numbers used for identifying a [Mobile Device] [Phone subscriber]. The [IMSI] is stored in the [SIM]/[UICC], i.e. the card inserted into the mobile phone, and each
* [IMSI] uniquely identifies the [Mobile Device]
* [MSISDN] is the number used for routing calls to the [Phone subscriber].
[IMSI] is often used as a key in the [Home Location Register] ([HLR]) ("subscriber database") and [{$pagename}] is the number normally dialed to connect a call to the [Mobile Device]. While the [SIM]/[UICC] has a unique [IMSI] that does not change, the [MSISDN] can change in time, i.e. different [MSISDNs] can be associated with the same [SIM]/[UICC].
The [SIM]/[UICC] contains an [Integrated Circuit Card Identifier] ([ICCID]) which contains the [Primary Account Number] which can then be used for [Financial] transactions.
[{$pagename}] follows the numbering plan defined in the [ITU-T] recommendation [E.164].
An [example] of the [MSISDN] format is shown below:
* [Mobile Country Code] ([MCC]) can be up to 3 digits.
* [National Destination Code] ([NDC]) usually 2 or 3 digits.
* [Subscriber Number] can be up to a maximum 10 digits.
