View and edit your Access Point Name (APN) on your iPhone and iPad
Learn how to view and edit the APN for cellular data services on your iPhone and iPad.
The Access Point Name (APN) defines the network path for all cellular data connectivity. Some carriers require you to enter your APN settings to set up your cellular service.
You can only edit or view your APN on your iPhone and iPad if your carrier allows it. If you can't modify your APN settings, contact your carrier.
Enter your APN settings automatically
If your cellular carrier 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 > Cellular > Cellular Data Network.
Tap Cellular Data Network.
If you don't see the option to use carrier settings, follow the steps below to enter your APN settings.
View and edit your APN settings
If you enter incorrect APN settings, you might lose cellular data connectivity and receive additional charges. Don't edit the APN unless directed by your carrier or mobile device administrator. Contact your carrier to verify the correct APN settings.
If your carrier allows it, you can view your APN settings in one of the following locations:
Settings > Cellular > Cellular Data Network
Settings > Mobile Data > Mobile Data Options > Mobile Data Network
If your device doesn't have either option, contact your carrier.
To change your 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 changes made to your APN settings. If you edit your APN settings before updating iOS, your settings will reset to the default values. You might need to reenter 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, you might need to contact your mobile device administrator to change your APN. If you change APN settings that a mobile device administrator set for you from a configuration profile, here's how to change it back:
On iPhone: Go to Settings > Cellular > Cellular 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.
