Usage notes
An MSISDN follows the ITU's E.164 numbering plan, with a maximum of 15 digits. The network maps the MSISDN, the public number, to the IMSI, the private identity on the SIM, which is how numbers can be ported to another carrier or moved to a new SIM. Developers encounter the term in messaging and carrier APIs.
