## Declaration

```swift
var allowsVOIP: Bool { get }
```

## Discussion

Discussion A read-only Boolean value that is true if the carrier allows making VoIP calls on its network, or false if not. If you configure a device for a carrier and then remove the SIM card, this property retains the Boolean value indicating the carrier’s policy regarding VoIP. If you then install a new SIM card, its VoIP policy Boolean replaces the previous value of this property.
