iOS: About cellular data network settings (viewing or editing the APN)
The Access Point Name (APN) defines the network path for all cellular data connectivity. You can view or edit the APN for cellular data services on iPhone and iPad. This information applies to you if your device uses a SIM card and your carrier allows you to edit the APN.
Edit and view your APN settings
If your APN settings are incorrect, you may lose functionality, such as cellular data connectivity, and receive additional charges. Don't edit the APN unless directed by your carrier or IT manager. Contact your carrier to verify the correct APN settings.
If your carrier allows it, you can view the APN settings on your iOS device in Settings > Cellular > Cellular Data Network.
To edit the settings, tap each field and enter the details provided by your carrier. The settings should save automatically. 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 a configuration profile with the correct setting.
Note: 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 reset to the default values. You may need to reapply your settings after an iOS update.
Reset your APN settings
To revert to your carrier's default APN information, tap Reset Settings on your iPhone. If you installed a configuration profile, the profile's default information will be used instead.
If you're 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 to change your APN. If you change an APN that an IT manager set for you by using a configuration profile, you can tap Reset Settings to change it back:
- iPhone: Tap the Reset Settings button in Settings > Cellular > Cellular Data Network.
- iPad: Remove the configuration profile and add it again.
For more information, contact your IT manager.
IT managers: You can use Apple Configurator, OS X Server Profile Manager, or another Mobile Device Management solution to change advanced settings on iPhone and iPad, including the APN. Learn more on iOS Enterprise Deployment Resources and the iPhone Enterprise Support site.
