MMS FIX! - May resolve issues for some

Hi everyone,
Ive been testing the new ROMs for a while now and have flashe everything except for nprussells release from today. On all of them (with or without MMS fix) I found that MMS wouldnt work. Retesting MMS on most of the ROMs I've found that deleting all original APNs (as we normally do anyway) then adding 2 APNs as below resolves all MMS issues. I can now receive and send MMS without any additional apps, mods, etc.
To add 2 APNs: add one for data, call it whatever you want and add information ONLY for data access (no mmsc, etc) leave these as they are by default. Also leave APN type and authenication.
Then for the second APN add only the data server + MMS info. Again leave authentication blank. Then under APN type type mms.
Do not add any more info for data access and make sure that only the data APN can and is selected. Also ensure that there are no other APNs.
UK Network settings: http://www.filesaveas.com/gprs.html
Hope this works!
ps I know that this has officially been resolved but I am sure Im still getting problems with not receiving some texts :s

I can't get MMS to work, could you expand a little more on your fix?
ie what exactly I would have to do ? (complete N00b here )

Hi,
Please provide more details on the problem - which ROM are you using and what have you done so far?
In detail you should download APN backup & restore from the market and use it to delete all APNs.
Then go to wireless settings, mobile network, access points.
Add two new APNs as described above - remember to save them both and set the data APN to active. Also make sure that mobile data is enabled. Then you may need to restart you phone although I didnt have to.
If you need specific settings then please let me know which network you are on and in which country so I can help you further

Could you help me aswell? i'm on vodafone UK currently using VillainROM 5.2
Thanks

pay as you go or pay monthly?

I'm using villain 5.2 and I'm on o2 monthly
I tried the adb shell fix, but it couldn't find the carriers database to update. I then tried manually entering them in the mobile settings and it still doesn't work

but there some of the fields are missing

Cheers for the link, but I still can't get MMS to work. I just get the error message not download, transient failure
I've tried every setting I can find on the internet and none of them work.

According to the O2 forums, you can only use one APN, so all settings have to be put into one (I have tried setting up 2 different ones and that didn't work either)

looks correct to me, u need a smartphone data plan for this to work i believe. My sim is non-smartphone data plan and it wont work for me, but when i stick in someone elses smartphone sim, these settings work.

Yeah. No idea how, but MMS now works. Didn't change a thing...

Add ",hipri" after supl.

WORKING Straight Talk MMS Settings for Ion

So the Ion, for some reason has been tricky to get the MMS settings correct. I was at my wits end, and about to get rid of my beloved Ion due to the inability to send and receive MMS. Here's the settings I use, set them EXACTLY, any deviation, they will NOT work, trust me, I tried!
Delete any previous Straight Talk APN settings.
Create new APN.

What was catching myself, and many others I've seen asking the same question, was the addition of the MMS APN. I as well as them, were setting it all as ONE single APN. TWO APN's ARE NEEDED!
Soon as I set them and checked the Straight Talk box, it started sending and receiving quickly! Pictures go both ways without any issues at all, and last night at work I ran speed tests and averaged roughly 5mbps.
This was exciting to me and hopefully it helped someone else out. Now you're free to enjoy $45/Mo unlimited everything on your sexy Ion!

Just tried this now. I was only able to send pictures when connected to wifi for some wierd reason. I just got the "queved for sending" message. Doesn't look like this has resolved it for me. let me try a power cycle. You have the default "straight talk" named apn the one with the green bubble next to it in your setting correct?
Thanks for the advice will let you no if get it working or not.

Yeah, when I made it the Straight Talk MMS setting didn't have a checkbox next to it. However after resetting phone and doing this again it does? Odd. I'll see if I can figure out

Try creating with wifi off? Set APN type as mms, not MMS. Worked for me. That's the only changes I made

Changing MMS to lowercase had it working for about ten minutes. Still having troubles.

Working fine for me still

Try these setting on my ion, still not working. Saw the 4G icon flashed for about 2sec and went away, 2 whole sec of hope. :/ Question, does the phone have to be unlock first? its still lock with ATT, getting my unlock code soon I hope. Thanks

Working perfect for me under 1 large apn without the data proxy too.

I spent many sleepless nights looking for proper APN settings on Straight Talk's B.Y.O.P. plan (AT&T) for my unlocked Sony Xperia Ion (LT28at) device, here are the ones I came up with by messing around with multiple references, that work flawlessly; I get a near perfect 4G signal nearly everywhere and can send and receive MMS messages very fast:
You need you create 2 APNs and select the one named "straight talk"; The APN titled "mms" will be unselectable if done correctly.
Delete any other APNs if possible.
These settings are CAPs sensitive and sorry for the spaces in the URLs, don't have permission for posting hyperlinks yet, so leave out the spaces.
When I created this APN setup I did it with the Wifi off and then restarted the phone, and after reboot, worked great with Wifi.

Awesome, almost bought a Nexus 4 myself, hope you're loving it! So glad to hear it worked for you, haha, spent like 30 minutes typing that up, haha. I doubt I could have done it without the creator of this thread, so shout out goes to joe3681 for figuring out you had to make separate APNs.

Hey everyone add the word hipri in

Now I get faster speeds on straigh talk. Went from 1mb to 5mb download with this simple change.

Info on new sim (sort of)
Just thought I would give an update for all of us still hanging on to the ION
I just got a new ST ATT type sim card. I just knew for certain that with the new sim card that the standard APN settings would work
I was disappointed to say the least, LOL
Still the only ones working for me are in my post on page one.

only settings that worked for me, thank you so much <3333

None of these working
None of the settings listed work for me. When I try to send a picture it says "queued for sending when service is available" and when someone sends me a picture I get "message not downloaded". 2 APN's do not work. I also do not get any 4G with these settings. At least with straight talk's settings I get 4G LTE but of course nothing works that way neither.
Any more settings I can try?

Not really sure I've had an ion for 2-3 yrs and in the beginning when I lived in Atlanta it worked. But now living in Indiana i can't get any (MMS) to work ? I have wonderful 4g though

APN Settings

Aloha-
I have a Verizon Galaxy Nexus, running CM11 M9, on the PagePlus service. Everything was working fine until a few days ago where mobile data stopped working. Upon research, it appears my APN setting must change to the following.
APN: vzwinternet
MMSC: http://mms.vtext.com/servlets/mms
MMS Port: 80
MCC: 310
MNC: 012
APN Type: internet+mms
However, the APN settings are not available. I tried flashing to another rom (Pure_Toro 4.9 Stock ASOP) and could not find the APN settings either. I am at a loss as to how to change the APN settings. i did attempt to us an app call Change APN. I converted it to a system app but could not make the changes...
Any help would be appreciated.
