APN: phone

mmsc: http://mmsc.mobile.att.net

mms proxy: proxy.mobile.att.net

MMS port: 80

MCC:310

MNC:410

APN type: default,supl,mms,hipri

Update 7-24: It has also come to my attention that port 8080 works. I am under the impression that it is higher security for sending MMS messages. Thanks!



Update 2 7-24: User xxxSuperserieSxxx has reported the following working from an AT&T Infuse to and from another AT&T phone. I need testers for this fix as well for MMS messages to users on OTHER carriers (T-Mobile, Sprint, Verizon, etc). Thanks guys.

Update 8-13: For One X users only! Try changing "APN" to pta and add "fota" to APN type. Then make a second APN with the above settings. pta is for LTE, but you need a fallback when you aren't in an LTE covered area I believe. If I had an LTE phone i could test this, but sadly I don't yet.



Update 8-17: I'm now supporting ANY AT&T device on this thread. If I don't already have it listed, I will find a setting that works for you and test it with anyone who needs me to do so and asks nicely.



Update 8-21: For Inspire 4G owners only! You may want to include "fota" and "admin" in APN Type, separated by commas. For example, yours would read something like: APN type: default,supl,mms,hipri,admin,fota.



Update 9-15: For AT&T Samsung Galaxy S3 owners only! Use the following to achieve LTE speeds and mms functionality:

APN: pta

mmsc: http://mmsc.mobile.att.net

mms proxy: proxy.mobile.att.net

MMS port: 80

MCC:310

MNC:410

APN type: default,supl,mms,hipri





Update 1-1: It seems a though AT&T is switching to a unified APN for all phones. This is the "phone" APN in the OP. This should be the default for all newer AT&T phones, whether they are LTE or not. This includes the Nexus 4 as well. Try it! Bottom line: Use the APN in the pictures above.



Hey everyone,As many of you know, APN switching can be a sporadic mess in AOSP roms. We've either had to deal with it or have a single APN at standard HSPA speeds. The following is a SINGLE APN solution that has been working after hours of trial and error and testing. I can't guarantee it will work for everyone, but please use this as a reference for future builds. So far so good.After hours of testing on many ROM's, I feel like these are appropriate APN settings that everyone can use. I've gotten my best data speeds ever AND MMS to work without having to worry about APN switching. Thanks to all the testers! This has been officially moved to the development thread as a reference to AOSP and AT&T phone developers.Disclaimer: May not work for everyoneInstructions for editing APN:1. Menu2. Settings3.
