The subsequent sections will provide detailed information regarding the specific parameters required for a functional configuration, troubleshooting common issues, and methods for ensuring optimal data connectivity on Android devices operating on AT&Ts mobile network.
1. Name
Within the context of configurations for Android devices connecting to the AT&T network, the ‘Name’ field serves as a descriptive label for the APN profile. While the ‘Name’ itself does not directly impact the functionality of the data connection, it plays a crucial role in user identification and management of different APN settings. This distinction is vital as users may have multiple APN configurations stored on their device, potentially for different carriers or network types. Selecting the wrong APN, even with correct parameters, can lead to confusion and troubleshooting difficulties. For example, a user traveling internationally might save their home AT&T APN alongside a local carrier’s APN. The ‘Name’ field clarifies which configuration to use.
The absence of a clear and descriptive ‘Name’ can lead to errors in APN selection, especially when users need to switch between configurations. In some cases, default or generic names such as “Internet” or “Mobile Data” are assigned automatically. These names offer no differentiation between APNs, making it challenging to isolate the specific configuration required for the AT&T network. Therefore, best practice involves using a specific and recognizable name, such as “AT&T Data” or “AT&T Broadband,” to ensure accurate APN selection. This is particularly important in multi-SIM devices where multiple carriers are active.
In conclusion, while the ‘Name’ parameter in an profile on Android does not directly influence connectivity, its descriptive function is essential for effective APN management and troubleshooting. A well-chosen name prevents confusion and assists users in quickly identifying the correct configuration for their AT&T data connection. The user experience is improved by clearly labeled profiles within device settings.
2. APN
The Access Point Name (APN) functions as the core identifier within the data configuration on Android devices. Regarding configurations tailored for AT&T’s network, the APN is the specific gateway address through which the device connects to AT&T’s mobile data infrastructure. Incorrect APN values result in the device being unable to establish a data connection. For instance, if the specified APN does not match AT&T’s current settings, the device will fail to authenticate, preventing internet access, MMS delivery, and other data-dependent services. The APN is therefore the primary causal factor in establishing a functional data link.
Real-world examples underscore the APN’s significance. Consider an unlocked Android phone brought to the AT&T network. Unless the correct APN is manually configured or automatically pushed via network provisioning, the device will be limited to voice and basic SMS functionality. Even with a valid AT&T SIM card and cellular signal, data services remain unavailable. Similarly, a device that previously functioned correctly may lose data connectivity if the APN settings are inadvertently altered during a software update or system reset. Understanding the APN parameter enables users to diagnose and rectify these connectivity problems, confirming the APN reflects the carrier’s specified value.
In summary, the APN is a central component within the specific configurations. It acts as the essential conduit to AT&T’s data network.

An incorrect “Port” number, even with a valid proxy address, will prevent the device from connecting through the proxy, thus disrupting data access. For example, if a proxy server is running on port 8080, but the “Port” setting is set to 80, the connection will fail.
-
Standard Configurations
In most standard configurations for AT&T , the “Proxy” field is left blank, rendering the “Port” setting irrelevant. This is because AT&T’s standard network configuration does not require devices to connect through a proxy server for data access. The absence of a proxy implies a direct connection between the device and AT&T’s network infrastructure. Therefore, the “Port” field would not be utilized in these configurations. Any value set would not affect the data connection.
-
Troubleshooting Scenarios
When diagnosing connectivity problems on an AT&T Android device, one should verify that the “Proxy” setting is indeed empty, which should also imply that the “Port” setting is irrelevant. If the “Proxy” field contains an address, ensuring that the “Port” value matches the proxy server’s configuration is crucial. Often, incorrect “Port” settings are the result of manual configuration errors or outdated instructions. This is because, typically, users copy/paste settings directly from guides, potentially inheriting errors. Ensuring the correct “Port” value is aligned with the specified “Proxy” address is essential.
In conclusion, while the “Port” setting within configurations for Android devices on AT&T is typically irrelevant due to the absence of a required proxy server, it becomes a critical parameter when a proxy is explicitly configured. Accurate configuration of both the “Proxy” address and the corresponding “Port” number is necessary for enabling data connectivity through a proxy, which is crucial for data routing and validation. As such, the “Port” parameter warrants attention during troubleshooting only when an external proxy has been set within the profile.
5. Username
