# CTCellularPlanStatusAuthorization.notSupported

A status that indicates the system can’t determine authorization.

## Declaration

```swift
case notSupported
```

## Discussion

Discussion The framework returns this status when both of the following criteria are met: The given phone number doesn’t match a cellular plan on the device. At least one active cellular plan has a phone number the system can’t confirm. Unlike CTCellularPlanStatusAuthorization.notAuthorized, this status doesn’t indicate that the person denied authorization; it also doesn’t identify a permanent condition. Although the status might be permanent for the given phone number, your app can call requestAuthorization(forPhoneNumber:completion:) again later to check, for example, if an underlying carrier-side condition changed.
