Cannot send MMS - AT&T Galaxy Note 3 Q&A, Help & Troubleshooting

I cannot send nor receive MMS messages. That is any kind of picture and multimedia text.
I can send and receive regular texts just fine. This started about a year ago on my Note 2. I used to fix it by switching to the wap.cingular APN with the following settings for the MMS server:
MMS Proxy: 66.209.11.32
MMS Port: 8080​
but now this apn does not work on my Note 3 and hence my ability to receive MMS is gone with it.
the proxy.mobile.att.net and the wireless.cingular.com on port 80 have never worked.
Of course ATT Customer and Technical Services have NO CLUE. Calling them about this has been a huge waste of time over the year. Nothing new there.
Any ideas?

Now this one connects to the network but it defaults back to the stock apn after a few minutes. Not sure if its just my phone or not so that's why I posted it anyway. Because someone had asked for it..

I read this thread before and somehow I missed your message. I just want to give you a big "Thank You".
I guess I have to read up more on the applications I am using to know how they operate. To me the Ad-Blockers would mostly block flash and js on websites and other apps. How the hell can they block MMS?!?!
I guess what threw me off was the fact that a different apn would still work with the Ad-Blocker and these ad-blocking programs would be among the first apps I install on any new phone so I never noticed MMS working without them.
How did you figure it out out?

did you know that some of these APNs will not work with the note 3. It's like the radio is turned off or something.

I don't know why Adblocker blocks MMS or how it does. I figured it out because someone told me haha just passing along info that I know

MY mms solution
I use AdAway and have never had any interference with sending or receiving mms. However, I have had a complete inability to send/receive mms within the past 4-6 weeks on my SG Note and now my SG Note 3. I found a solution today if using any non-native messaging app. I have posted my solution here: http://forum.xda-developers.com/showthread.php?p=47057113#post47057113.
I hope it helps anyone else having mms problems.

Oh my god. Thank you, thank you, THANK YOU! I've been having problems with MMS for MONTHS, I've scoured the internet, spent an hour on the phone with AT&T, removed adblock, reset my phone and it works perfectly now.
If only I had found this thread sooner.
Thanks! :good:

How old is your Sim card? Maybe you need a new one.

No data / MMS (can get data to work but not both)

I was unable to get data & MMS to work at first. Been playing around with the APN settings. I can get data to work with quite a few different APN settings but can only get MMS to work with one and cannot get both to work at the same time.
Any help is greatly appreciated...!!!

tried this one too - works for data but no MMS -
http://forum.xda-developers.com/showthread.php?t=1338109
I'm in the same boat. Yesterday my mobile data stopped working. Couldn't send/recieve texts... thought everyone hated me for like 5 minutes before I figured it out hahaha. Gonna call up AT&T and yell at them
Turns out AT&T accidently removed my MMS and Data plan without any authorization. Got it restored and all the problems are solved!
camit34 I had that problem when I first got my vivid. Had to be escalated to tier 2 support and they finally sent some kind of reboot/update/something that fixed it. I wish I knew what they did to tell you, but she had tried multiple things and we don't know which one it was. Good luck.

What are all the different apn that at&t user can put in the vivid

[Q] AT&T Xperia TL LT30at apn

Could someone please post your default apn from the Xperia TL LT30at from AT&T?
I moved on to an unlocked ZL and I downloaded the settings but I believe the apn is different.
I would like to enter the TL's default to see if improves speed.

Hi, I just got an Xperia T and am having trouble getting it to work with the ATT data network (ATT is no help surprise surprise). For a 'Xperia T' will any of the APNs above work, or will I need something else?
Thanks!!

XT1095 PURE issues with Lollipop (.11) and MMS

I am having issues with MMS on my phone. I recently switched from AT&T to T-Mobile and I am using my Pure Edition Moto X 2014.
I believe I have the APNs setup properly in settings:

APN Type: none (Internet+MMS results in no data)
APN Protocol: IPv6
APN Roaming Protocol: IPv4
Bearer: Unspecified
Data, calls, SMS all work great whether or not I am on Wifi or Mobile Data. My issue comes when I am on Wifi and try to send or receive an MMS, the phone seems to cut off mobile data when I am on Wifi, so I am unable to send or receive an MMS unless I turn off Wifi

I appreciate you basically posting the same APN. I am trying to track down why the phone is not turning on mobile data to send and receive MMS. It will just queue the message til when I turn off Wifi.
