The Access Point Name (APN) defines the network path for all mobile data connectivity. Some network providers require you to enter your APN settings to set up your mobile service.
You can only edit or view your APN on your iPhone and iPad if your network provider allows it. If you can't modify your APN settings, contact your network provider.
Enter your APN settings automatically
If your mobile network provider supports this feature, you can populate your APN settings automatically in iOS 16 and iPadOS 15 and later:
- Insert your SIM card or use eSIM.
- On your iPhone or iPad, go to Settings > Mobile > Mobile Data Network.
- Tap Mobile Data Network.
If you can't see the option to use network provider settings, follow the steps below to enter your APN settings.
View and edit your APN settings
If you enter incorrect APN settings, you may lose mobile data connectivity and receive additional charges. Don't edit the APN unless directed by your network provider or mobile device administrator. Contact your network provider to verify the correct APN settings.
If your network provider allows it, you can view your APN settings in one of the following locations:
- Settings > Mobile > Mobile Data Network
- Settings > Mobile Data > Mobile Data Options > Mobile Data Network
If your device doesn't have either option, contact your network provider.
To change your settings, tap each field and enter the details from your network provider. The settings should save automatically. Depending on your network provider, you may not be able to change the mobile data settings. If your network provider needs a different APN setting, you may be able to use a configuration profile with the correct setting.
Unless you're using a configuration profile, updating iOS will reset any changes made to your APN settings. If you edit your APN settings before updating iOS, your settings will reset to the default values. You may need to re-enter your settings after an iOS update.
Reset your APN settings
To revert to your network provider's default APN information, go to Settings > Mobile > Mobile Data Network > Reset Settings. If you've 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, you may need to contact your mobile device administrator to change your APN. If you change APN settings that a mobile device administrator has set for you from a configuration profile, here's how to change it back:
- On iPhone: go to Settings > Mobile > Mobile Data Network, then tap Reset Settings.
- On iPad: remove the configuration profile and add it again.
If you're a mobile device administrator, you can use Apple Configurator or another mobile device management solution to change the APN and other advanced settings.
