iOS: About cellular data network settings (viewing or editing the APN)
Summary
This article explains how to view or edit the Access Point Name (APN) for cellular data services on iPhone and iPad. This information applies only if your carrier allows editing the APN.
The APN defines the network path for all cellular data connectivity. Incorrect settings may result in a loss of functionality or features and may result in additional charges. Contact your carrier to verify the correct APN settings.
Note: This information applies to devices that use a SIM card.

You can view the APN settings on your iOS device in the following location if it's permitted by your carrier:
- iPhone: Settings > General > Network > Cellular Data Network
- iPad: Settings > Cellular Data > APN Settings
| iPhone | iPad |

Tap each field and enter the APN settings provided by your carrier. The settings are saved automatically.
You can tap Reset Settings on an iPhone to revert to your carrier's default APN information. If you have installed a configuration profile, the profile's default information will be used instead.
Additional Information
Unless you're using a configuration profile, an update of iOS resets any modifications made to the APN settings. If you edited your APN settings before updating iOS, these settings will be reset to the default values. You may need to reapply these settings after an iOS update.
Depending on your carrier, you may not be able to edit the cellular data settings. If your carrier needs a different APN setting, you may be able to use the iPhone Configuration Utility to install a profile with the correct setting.
If you are using iPhone or iPad in an enterprise environment, your IT manager may have set up a special APN for you to use. If this is the case, contact your IT manager for information on changing your APN. If you accidentally change an APN that was set for you by an IT manager using a configuration profile, you can change it back:
- iPhone: Tap the Reset Settings button in Settings > General > Network > Cellular Data Network
- iPad: Remove the configuration profile and then add it again.
For more information, contact your IT manager.
IT managers: You can use the iPhone Configuration Utility to change advanced settings on iPhone and iPad, including the APN.
Note: An incorrect APN may result in a loss of functionality or features, such as cellular data connectivity, and may result in additional charges. Do not edit the APN unless directed by your carrier or IT manager and you have been provided the correct APN settings for your carrier and account provisioning.
