# carrierToken

A data object containing authorization information about the subscriber.

## Declaration

```swift
var carrierToken: Data? { get }
```

## Discussion

Discussion May contain nil if no token is available. The carrier API obtains this token from a carrier-provided server. The token authenticates your app to a server provided by the carrier, to prove that your app is running on a device owned by the subscriber.
