iPhone
Turning off Cellular Data does not affect your ability to make or receive phone calls or to use Wi-Fi networks for Internet connectivity, but you will be unable to:
- See the cellular data icons in the status bar (for example, 3G).
- Send or receive MMS messages. However, SMS and iMessages can still be sent and received.
- Retrieve or listen to new Visual Voicemail messages. To retrieve these messages, enable Cellular Data.
- Use Personal Hotspot.
You can adjust this setting from Settings > General > Network.

Additional Information
Depending on your carrier and iOS device model, the option to "Enable 3G" may not appear in Network settings.
