# serviceCurrentRadioAccessTechnology

A dictionary containing the current radio access technology registered to each service.

## Declaration

```swift
var serviceCurrentRadioAccessTechnology: [String : String]? { get }
```

## Discussion

Discussion The keys for the serviceCurrentRadioAccessTechnology dictionary are NSString objects, each of which represents a service. The entry associated with a key is nil if the service is not registered on any network. Although the actual value of a key isn’t important, you can also use it to get the carrier information associated with the service. To do so, pass the key to the serviceSubscriberCellularProviders dictionary.
