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 your iPhone and iPad. You can only edit or view your APN if your carrier allows it. If your device uses a SIM card and your carrier allows you to edit the APN, follow these steps.
Edit and view your APN settings
If your APN settings are wrong, you might lose 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 Options > Cellular Network. If you’re using a device outside of the United States, you can find your APN settings in Settings > Mobile Data > Mobile Data Options > Mobile Data Network.
To change the settings, tap each field and enter the details from your carrier. The settings should save automatically. Depending on your carrier, you might not be able to change the cellular-data settings. If your carrier needs a different APN setting, you might be able to use a configuration profile with the correct setting.
Unless you're using a configuration profile, updating 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 might need to reapply your settings after an iOS update.
Reset your APN settings
To revert to your carrier's default APN information, go to Settings > Cellular > Cellular Data Network > Reset Settings. If you installed a configuration profile, the profile's default information will be used instead.
If you're using an iPhone or iPad in an enterprise environment, your IT manager might 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.
If you're an IT manager, you can use Apple Configurator, OS X Server Profile Manager, or another Mobile Device Management solution to change advanced settings on an iPhone or iPad, including the APN.
