Common issues
Data works but MMS won't send. Check the MMS proxy as well as the MMSC. AT&T routes picture messages through proxy.mobile.att.net on port 80, and a missing proxy stops MMS while browsing still works.
No data on an unlocked or imported phone. Enter the APN by hand and restart: ENHANCEDPHONE on a 5G phone, NXTGENPHONE on a phone with only LTE. Unlocked phones often skip AT&T's automatic setup, so the APN field starts empty. A software update can clear it too.
No data on a tablet. Tablets use a different APN, Broadband, with no MMS settings. The phone APNs are for smartphones.
Frequently asked questions
Should I use ENHANCEDPHONE or NXTGENPHONE?
Use ENHANCEDPHONE on a 5G phone and NXTGENPHONE on a phone that only has LTE. AT&T uses both, with the same MMSC, http://mmsc.mobile.att.net, and the same MMS proxy, proxy.mobile.att.net on port 80. A phone on standalone 5G uses NRPHONE, which has no MMS settings, and tablets use Broadband. Capitals don't matter in an APN.
Do I need to enter AT&T APN settings by hand?
Usually not. AT&T owns its network, and most phones pull the settings automatically. You enter them manually when data or MMS stops working, often after a SIM swap, a factory reset, or moving the SIM into an unlocked phone.
How do I know it worked?
Turn off Wi-Fi and open any website. If it loads, data is working. For MMS, send a photo to a friend and confirm it goes through. A quick restart helps if either doesn't start right away.
Does AT&T support eSIM?
Yes. AT&T supports eSIM. Activation usually sets up the data settings automatically, so you rarely touch the APN on an eSIM line.
Why won't my iPhone let me edit the APN?
Many carriers manage the iPhone APN through a hidden configuration profile, so the fields are locked or missing. That's normal. Resetting network settings re-pulls the profile and fixes most iPhone issues without manual entry.
These settings didn't fix it. What now?
Restart the phone first. If data still won't connect, reset network settings and let the carrier re-provision. If only MMS fails, re-check the MMSC and make sure mobile data is on. APN settings can't fix a deactivated line, an unpaid balance, or a locked phone.
