AT&T APN Settings | Step by Step Guide


APN stands for access point network. The access path network is the path through which the SIM card of the phone interacts and connects to the internet. However, it is not necessary that the only connection to the internet is possible through it. APN is also used to connect the messaging services like MMS to the phone. Thus, you must know about AT&T APN Settings.

A more generalized definition of APN is that it is a way through which the connection to the internet and the sending and receiving of multimedia over the phone network is possible. The APN is supported by all forms of a network like GSM, 4G, 3G or even upcoming 5G network.

A mobile that wants to connect to the internet makes a request through the APN to which the network recognizes it and then confirms the connection.

The mobile network makes use of various forms of requests like WAP or GPRS. They are most common ways to connect. The APN of different network providers is different. So it is safe to assume that the connection mechanism is also slightly different.
