AT&T APN Settings FAQ
What is the correct AT&T APN for 5G?
The standard APN for AT&T 5G and LTE devices is 'nxtgenphone'. For older devices or specific data-only plans, 'broadband' might be used, but 'nxtgenphone' is the modern standard.
Do I need to change APN settings on iPhone?
Usually, iPhones update APN settings automatically via 'Carrier Settings Updates'. However, if you are using an unlocked phone or roaming, you may need to enter 'nxtgenphone' manually in the Cellular Data Network menu.
What are the MCC and MNC for AT&T?
The standard MCC for AT&T is 310. The MNC is typically 410, but can also be 280, 170, or others depending on your specific SIM and region. Always use the MNC your phone auto-populates if unsure.
Why is my data slow after changing APN?
Check if 'APN Protocol' is set to IPv4/IPv6. Using only IPv4 can limit performance on AT&T's modern network. Also, ensure you haven't exceeded your high-speed data cap.
How do I reset AT&T APN to default?
In the APN menu on Android, tap the three-dot menu and select 'Reset to default'. This deletes custom APNs and restores the SIM card's original configuration.
