    Under the carrier line in About Phone if you tap on Carrier on a Verizon IPhone 6S a line called NAI pops up and is your mobile number @vzims.com or @vzw3g.com. What does this mean and what is this used for? The PRL, and Voice and IMS are also displayed after you click on carrier too find this information.

    In short:
    In order to provide roaming services, it is necessary to have a
    standardized method for identifying users. This document defines the
    syntax for the Network Access Identifier (NAI), the user identity
    submitted by the client during network authentication. "Roaming" may
    be loosely defined as the ability to use any one of multiple Internet
    Service Providers (ISPs), while maintaining a formal, customer-vendor
    relationship with only one. Examples of where roaming capabilities
    might be required include ISP "confederations" and ISP-provided
    corporate network access support.
