The Access Point Name is set to define the network path for all the cellular activity on a device. You can view and edit the APN but only if your carrier allows you to. If you have a SIM card and a carrier that allows modifying the APN, here’s how you can change APN on iPhone or iPad.

The downside to having been using a wrong Access Point Name is that you may lose cellular data and also see some additional charges in your bill. So don’t edit the APN until you have been prompted to do so by your carrier or IT manager. You can always contact your carrier to check if the APN settings on your device are correct.

If your carrier allows, you can see your APN by opening the Settings app and then accessing the Cellular tab. In this tab, tap on Cellular Data Options and then on Cellular Network to view the APN.

If you reside outside the United States you can view your APN by accessing Settings, Mobile Data and then into Mobile Data Options. Further, tapping on the Mobile Data Network will show your APN settings.

If you are working in an enterprise environment, your IT manager may have configured a special APN. Contact him if you wish to modify the Access Point Name.

For doing the same on an iPad, remove the configuration profile and add it again. If you’re an IT manager and wish to change advanced settings including the APN, you can use Apple Configurator, OS X Server Profile Manager or any another Mobile Device Management solution.
