# getHintForPhoneNumber(_:completion:)

Provides an estimate of the system’s confidence of the existence of an active cellular plan for the device’s phone number.

## Declaration

```swift
class func getHintForPhoneNumber(_ phoneNumber: String, completion completionHandler: @escaping @Sendable (CTCellularPlanStatusAvailability, CTCellularPlanStatusAvailabilityConfidence, (any Error)?) -> Void)
```

```swift
class func hint(forPhoneNumber phoneNumber: String) async throws -> (CTCellularPlanStatusAvailability, CTCellularPlanStatusAvailabilityConfidence)
```

## Parameters

- `phoneNumber`: A phone number in https://www.itu.int/rec/T-REC-E.164 (for example, +15550001234).
- `completionHandler`: A closure the framework calls with the cellular plan availability, confidence level, and any error that occurs.

## Discussion

Discussion Upon completion, the CTCellularPlanStatusAvailability instance in the handler indicates whether the device has a cellular plan for the given phone number and the framework’s confidence (CTCellularPlanStatusAvailabilityConfidence) that the determination is true. Only call this method after you receive an CTCellularPlanStatusAuthorization.authorized status from requestAuthorization(forPhoneNumber:completion:) or getAuthorizationStatus(forPhoneNumber:completion:).
