# serviceSubscriberCellularProviders

A dictionary that contains carrier information about each service.

```
var serviceSubscriberCellularProviders: [String : CTCarrier]? { get }
```

## Discussion

The keys for the [`serviceSubscriberCellularProviders`](/documentation/CoreTelephony/CTTelephonyNetworkInfo/serviceSubscriberCellularProviders) dictionary are <doc://com.apple.documentation/documentation/Foundation/NSString> objects, each of which represents a service. Each entry in the dictionary is a [`CTCarrier`](/documentation/CoreTelephony/CTCarrier) object, which contains information about the subscriber’s home cellular service provider.

> Note:
> In this context, the “home” provider is the one with which the user has a cellular plan, as opposed to a roaming provider.

Although the actual value of a key isn’t important, you can also use it to get the current radio access technology associated with the service. To do so, pass the key to the [`serviceCurrentRadioAccessTechnology`](/documentation/CoreTelephony/CTTelephonyNetworkInfo/serviceCurrentRadioAccessTechnology) dictionary.
