carrierName
The name of the user’s home cellular service provider.
Declaration
var carrierName: String? { get }Discussion
The carrier provides this string, formatting it for presentation to the user. The value does not change if the user is roaming; it always represents the provider with which the user has an account.
If you configure a device for a carrier and then remove the SIM card, this property retains the name of the carrier. If you then install a new SIM card, its carrier name replaces the previous value of this property.
The value for this property is nil if the user never configured a carrier for the device.
