# carrierName

The name of the user’s home cellular service provider.

```
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.
