# CTCellularData

An object indicating whether the app can access cellular data.

```

## Overview

This property represents all access to cellular data. If the [`restrictedState`](/documentation/CoreTelephony/CTCellularData/restrictedState) is [`CTCellularDataRestrictedState.restricted`](/documentation/CoreTelephony/CTCellularDataRestrictedState/restricted), the app cannot use the cellular network.

## Topics

### Determining the Cellular Data Restricted State

[`restrictedState`](/documentation/CoreTelephony/CTCellularData/restrictedState)

The current state of cellular data restrictions.

[`CTCellularDataRestrictedState`](/documentation/CoreTelephony/CTCellularDataRestrictedState)
