What is an Access Point Name (APN)?

An Access Point Name (APN) is a gateway that connects your mobile device to the internet and MMS services provided by your carrier. It essentially acts as a bridge between your carrier's cellular network and the public internet. Without the correct APN settings, your device may be unable to surf the web, download data, or send multimedia messages. Proper APN configuration ensures that your device can communicate effectively with AT&T’s network, providing you with a seamless internet and messaging experience.
