When should you update your APN settings?

APN (Access Point Name) settings determine how your phone communicates with AT&T’s network, letting you access the internet, send messages, and use other data-dependent services. In more specific tech terms, these settings are network configuration parameters that allow your mobile device to connect to your carrier's cellular data network.

While most modern smartphones automatically configure APNs when you insert a SIM card or activate an eSIM, you may need to manually enter or modify them if you experience data connectivity issues or have recently switched carriers and brought your own phone to AT&T. You need correct APN settings to access the internet via data on your phone.

Read on for device-specific instructions to view or change your phone’s AT&T APN settings.

How to view and edit AT&T's APN settings on Android

If your phone shows SIMs, tap and select your SIM two times. If not, skip to the next step.

Since this Pixel phone displays SIMs, tap your SIM on the next two pages to access your APN settings.

When should you update your APN settings?

You should update your APN settings if you can’t access the internet on your phone or recently switched carriers. But first, go through our data connection troubleshooting guide to make sure your mobile data is correctly turned on before touching your APN settings.

Many carriers, including AT&T, require specific APN configurations for their network to function properly, otherwise you may have issues with mobile data access and very slow speeds. While most smartphones automatically configure APNs, you'll need to enter them manually if you see they are missing or incorrect in your settings.

Always use the exact APN details for your carrier and restart your device after making changes. Incorrect APN edits can disrupt your service, so only modify these settings when you know your phone is unlocked and compatible with AT&T’s network.
