Well I just fixed my own issue! I got MMS to work using the following settings. Let me know if anyone else has any luck.

I left the Internet settings exactly as explained in the OP's original post. I made the MMS settings as follows:

Name: AT&T

APN: wap.cingular

Proxy: wireless.cingular.com

Port: 80

Username:WAP@CINGULARGPRS.COM

Password:CINGULAR1

Server: not set

MMSC: http://mmsc.cingular.com

MMS Proxy: 66.209.11.32

MMS Port: 80

MCC:310

MNC:410

APN Type: MMS
[AT&T Samsung Galaxy S II SGH-I777] mchimney:
First MMS went through, this is a good sign.

Thanks =))
[AT&T Samsung Galaxy S II SGH-I777] Theaccomplice88:
Is there a difference between the unlimited plan and a 4G unlimited plan?
[AT&T Samsung Galaxy S II SGH-I777] rwj5279955:
Now I'm getting random data disconnects with the tweaked APN settings.

I went back to the default. It's like some of you guys described, as soon as data is needed 3G tries to jump to H+ and stalls. :confused:
[AT&T Samsung Galaxy S II SGH-I777] Theaccomplice88:
I just called ATT and they said the 4g unlimited data plan does not exist... when talking with the manager, I was told the only 4g plans available were the tiered data plans, and I know I use more than 2gb/month...
[AT&T Samsung Galaxy S II SGH-I777] ph00ny:
um 4g unlimited never existed. If you currently have an unlimited data plan then you can grandfather into the 4g unlimited plan
[AT&T Samsung Galaxy S II SGH-I777] Theaccomplice88:
But my plan doesn't show HSDPPB, it shows DPPB
[AT&T Samsung Galaxy S II SGH-I777] mchimney:
My understanding is this.

DPPB means unlimited 3G plan. If you're currently on this then you can tell them to bump you up to the unlimited 4G plan. I told them i wanted to change my plan based off of the SOC code. Now they had no idea what that meant, so it took a few call backs to find someone smart. Tell them the SOC code is HSDPPB, and you'll probably need a separate IMEI (atrix, inspire, infuse) because i made the mistake of telling them my galaxy s2 imei and that came in the system as unrecognized.

Now the weird part is, i had an atrix (still do but don't use it). I was looking at the account history and it seems i was never on the HSDPPB plan, only the DPPB. So i suspect my slow speeds on the atrix can also be attributed to not being on the correct data plan, even though they told me time and time again i was.

I could be 100% wrong in this, but this is how i understand it haha.
[AT&T Samsung Galaxy S II SGH-I777] mattism78:
I need to figure a way around the IMEI number. I called AT&T and told them that I had an Infuse. They asked for the IMEI number and I told them I couldn't get to it since I was using the phone. She then told me that I was using a device they couldn't identify. She noted that I was no longer on an iPhone but wasn't able to determine what device I was on.
[AT&T Samsung Galaxy S II SGH-I777] Techvir:
The new apn did help me, even though there is no 4G coverage in my area.

( Dont know why it shows H+ during data usage even without the said 4g coverage . This was there before too )
[AT&T Samsung Galaxy S II SGH-I777] brandenk0:
Just out of curiosity what speeds are you guys getting? With full bars I have gotten a top of speed of 8mbps down and 1.27mbps up. Also I'm not on any 4g data plan I'm actually using the plan that I had on my iPhone (I know, I know, bad decision on my part.). So are these speeds what AT&T consider 4g?
[AT&T Samsung Galaxy S II SGH-I777] Techvir:
i get way less

around 3Mbps download and 1.2 mbps upload
[AT&T Samsung Galaxy S II SGH-I777] mchimney:
I don't know about legitness, but what about going to the AT&T store and just using an IMEI off of one of the display model phones
[AT&T Samsung Galaxy S II SGH-I777] xxmwxx:
I just went to an AT&T store and I had an awesome rep that just suggested I try to google an Atrix IMEI. That's exactly what I did and I just gave that to him and he was able to change my plan from the unlimited iphone on to the unlimited 4G plan..
[AT&T Samsung Galaxy S II SGH-I777] rwj5279955:
The person I spoke with took the IMEI off my girlfriends Inspire.

Same thing, while getting mine ironed out, the tech noticed the Inspire was on the wrong plan too. Even though I was assured multiple times the plan was correct and nothing needed to be done. At least most of us are savvy enough to sort it on our own:D

In other news, my data speeds hover around 3mb up. Top out around 6. Actually seems slower since the plan change.:confused:
[AT&T Samsung Galaxy S II SGH-I777] rc50won:
I am getting ready to replace my IP4 with the GII so I just check my plan on line and I have:

GPRS WAP UNLTD DOM - CMB1

I have the iPhone Unlimited Plan but this SOC does not agree with what I am seeing in this thread. Does anyone know what CMB1 is?

Thanks!

M
[AT&T Samsung Galaxy S II SGH-I777] xxmwxx:
It's the iPhone unlimited plan. It's the same one I had before I got the SGS2 and went to AT&T to have them replace it with the unlimited 4G plan.. Just make sure you tell them you have a 4G phone and give them an IMEI off of an Atrix or any other 4G phone they carry so their system will open the 4G option for you.
[AT&T Samsung Galaxy S II SGH-I777] AJerman:
Because the network is sending an HSPA+ signal to your phone. That was just a software upgrade on the towers. What you're waiting for is the enhanced backhaul and possibly (probably) a cap to be taken off or at least raised on the towers in your area.
[AT&T Samsung Galaxy S II SGH-I777] Techvir:
Thanks for the reply
[AT&T Samsung Galaxy S II SGH-I777] rwc3b:
Where can I find these 4G IMEI numbers? It's not easy to google them
[AT&T Samsung Galaxy S II SGH-I777] mrvirginia:
i just went in and told them i bought an Infuse 4G off of someone and the guy used an IMEI off of his phone which was an Inspire :)
[AT&T Samsung Galaxy S II SGH-I777] mattism78:
So, I got a Infuse IMEI. I called AT&T and tried getting them to switch me over to the HSDPPB the woman told me she switched it over but it has not reflected on my account yet. I don't see any data speed difference. I tried the new APN set up and it didn't really work out so I switched back to default.
[AT&T Samsung Galaxy S II SGH-I777] juicedog:
You may want to call AT&T back and double check.

When I called AT&T to switch from DPPB to HSDPPB, the rep spent a few mins trying to switch the plan and initially told me that it was done. But it was not reflected in my online account, so I asked him to double check. He put me on hold for another few mins and came back and said the system didn't take the change... and he couldn't get my unlimited plan back!! So I'm now on the 2GB limited plan until AT&T tries to get my unlimited plan back... The rep told me it will take 10 days to resolve it.

Not good...
[AT&T Samsung Galaxy S II SGH-I777] mattism78:
I'll give it another shot tomorrow. 12hrs of work plus an hour on the phone with AT&T is enough for one day for me.
[AT&T Samsung Galaxy S II SGH-I777] rwj5279955:
It won't reflect on your account until the next business day, usually. That's what they told me. and they were right.
[AT&T Samsung Galaxy S II SGH-I777] xxmwxx:
Go to google and search for "atrix 4g imei" and click on the 4th result. It has a picture of the IMEI.. That's the one I used, should work fine.

That's weird, mine updated instantly.. Could be a fluke...
[AT&T Samsung Galaxy S II SGH-I777] rwc3b:
thanks. I assume imei numbers are unique to the phone so will att find something fishy if it's used more than once?
[AT&T Samsung Galaxy S II SGH-I777] xxmwxx:
NP. I Don't think so. I've used that number twice for 2 different SGS 2 devices... It might depend on the rep you get (the one I had at the store just told me he can use it twice without a problem)
[AT&T Samsung Galaxy S II SGH-I777] rwc3b:
I wonder if bribing a rep with a Lincoln will get me that plan instead. Or will I get in trouble and be booted out of unlimited altogether?
[AT&T Samsung Galaxy S II SGH-I777] xdard:
When typing in values by hand, do not ever touch the MCC and MNC values. These values are a network filter for the big database of APN's in android, and are provided by your SIM. If you put in other MNC and MCC values than your phone provided when creating a new APN name, it will not be used with your current SIM. Worse: you won't be able to get that data back you have typed in, until you insert a SIM with those MNC/MCC values you just typed.

This is generic important android knowledge for everybody who has a SIM card of a network provider who does not exist anymore.

My girlfriend has an original Orange SIM, who's network has been taken over by T-Mobile without SIM replacement. This means you have to type in the T-Mobile settings by hand with the Orange MNC/MCC network identifiers (you can't copy/paste the settings from the phone because you are not able to see the real T-Mobile settings without an original T-Mobile SIM).
[AT&T Samsung Galaxy S II SGH-I777] mattism78:
I googled infuse 4G and found an unlock video where they clearly show the imei. That's what I used.
[AT&T Samsung Galaxy S II SGH-I777] RMXO:
forgive me for not reading the whole thread but has anyone been able to switched over to an unlimited smartphone 4G plan. I tried to switch my grandfathered unlimited plan to an unlimited smartphone 4G but the CS rep told me I couldn't. She said I would lose my grandfathered unlimited plan if I switched over to 4G with a 4GB cap. Guess I'll try again later.
[AT&T Samsung Galaxy S II SGH-I777] Techvir:
I called today and was told the same thing. The rep said the 4G plan had a cap of 4Gb and that would cost 35 $ . I am going to call another rep in sometime and see what they say
[AT&T Samsung Galaxy S II SGH-I777] xxmwxx:
Yeah. I bunch of us did. That's BS. Once they input an IMEI of a 4G device into their system it automatically opens up the option of an unlimited 4G plan (if you had the unlimited iPhone one).

The first time I spoke to someone on the phone every time I told her 4G she thought I was referring to the 4GB plan and not the 4th Generation network they advertise relentlessly - I ended up going to an AT&T store to get it done. Just make sure you give them an IMEI number from a 4G device... When they tried my SGS2 IMEI their system thought I had a blackberry (for some unknown reason).
[AT&T Samsung Galaxy S II SGH-I777] RMXO:
Good to know it isn't only me. Let me know how it goes when you call again. I'm going to do the same later on the day.

If this is a sign then keeping a grandfathered unlimited plan isn't worth it since they won't let you carry it over to 4G. Switching to an unlimited MediaNet is probably the way to go but I'm afraid they will kill it once they fully implement LTE down the road.
[AT&T Samsung Galaxy S II SGH-I777] mattism78:
There was an article on android central about being on the unlimited plan and 4G. Just ask for a supervisor if you have someone who is saying no. I'll link the article when I get home.

http://www.androidcentral.com/att-clarifies-their-4g-policy

Link with response from AT&T.
[AT&T Samsung Galaxy S II SGH-I777] daraj:
Just walk into AT&T store and grab the imei from an Inspire displayed
[AT&T Samsung Galaxy S II SGH-I777] rockky:
Hey

Any value in setting network mode to Wcdma only?

And

Off topic I know but anyway on new account to get unlimited data?!

I'm two weeks in and already over my 2G Max for gods sake lol!

Otherwise back to Sprint and wait for Within'.

Thanks for any insight.
[AT&T Samsung Galaxy S II SGH-I777] Techvir:
Finally got to an agent who was able to change the plan for me.

There is no additional charge for changing over to a the unlimited 4g plan.

Now where in the account do i look to confirm the change. Where is this HSDPPB ?

( i have not noticed any change in speed using speednet testing )
[AT&T Samsung Galaxy S II SGH-I777] RMXO:
That's what I did also but I got the Infuse 4G instead. On the phone with a CS Rep now. Just got off the phone, they said once they added my new IMEI, I was switched over to an Unlimited Smartphone 4G plan.

I would like to know this also. Mine still shows as Smartphone Personal.
[AT&T Samsung Galaxy S II SGH-I777] juicedog:
Log into your AT&T account and go to "Manage Features." Under Smart Phone bundles, you can click on the link "SmartPhone Personal." A pop-up screen will come up and if you look at the URL carefully, you will notice "=HSDPPB" at the end, instead of "=DPPB."

I did manage to be on the HSDPPB plan and tried every possible APN, including OP's, Atrix, Inspire, default setting, old Aria, etc. In San Francisco, I only get 2Mbps down and 1Mbps up at best. Actually with OP's "phone" APN, it never goes over 0.5Mbps down/up. Maybe 4G is not rolled out in San Fran?

Anyone else in San Fran getting better down/up speed? With OP's APN? Or any other APN settings?

Thanks.
[AT&T Samsung Galaxy S II SGH-I777] xxmwxx:
Log into your MyAT&T account and go to Wireless > My Wireless Service > Usage & Recent Activity

You will see it under "ADDITIONAL DATA PURCHASED USAGE"

It should say "Data

GPRS WAP UNLTD DOM - HSDPPB"
[AT&T Samsung Galaxy S II SGH-I777] Techvir:
THanks both of the methods work.

Confirmed to have HSDPPB

Re tested after a few hrs and looks like the speed has increased now.

I am using the default apn settings.

Will test with what the original poster said and see if there is a difference

Edit : Looks like the apn from the original poster is working slightly better... Not a huge difference though.

The main thing that helped me so far is changing to 4g plan
[AT&T Samsung Galaxy S II SGH-I777] aimfire72:
OK, I'm a little confused about this...

I'm using my iphone 4 sim (with an adapter) right now, on the old unlimited iphone plan (3G). Is it necessary for me to change that to a 4G plan in order to take max advantage of HSDPA speeds?

I'd prefer to keep my current plan if possible since I switch back and forth with my iphone, but having the "4G" speeds on my GS2 is more important to me. Thanks
[AT&T Samsung Galaxy S II SGH-I777] Techvir:
Even if u change to 4g plan , you still get unlimited. It will be called unlimited 4g plan.
[AT&T Samsung Galaxy S II SGH-I777] aimfire72:
Yeah, I know that, but wondering if I actually need the 4G plan to get the "4G" speeds, if it will help any.
[AT&T Samsung Galaxy S II SGH-I777] Techvir:
You might notice a small difference though and I dont think it hurts to try
[AT&T Samsung Galaxy S II SGH-I777] varunkumars:
How did you manage to change your plan. I called them once and asked them to put on 4G, representative said there is nothing like a 4G plan if your phone is capable enough you will get it she said.

What exactly did you ask for? Did you go to the AT&T store ?? Most of these representatives don't understand what we talk about.
[AT&T Samsung Galaxy S II SGH-I777] rwj5279955:
Tell them you wish to be on the same plan someone who just purchased an Inspire, Infuse or Atrix is on.
[AT&T Samsung Galaxy S II SGH-I777] Techvir:
Might be a good idea to call again and talk. There are some agents who know about the new plan.

It worked for me second time.

You can tell them to add ur imei and the new plan will pop up.
[AT&T Samsung Galaxy S II SGH-I777] RMXO:
I didn't see any reference to HSDPPB on my account until I changed to an Infuse IMEI, which automatically switched me to an Unlimited 4G plan per the CS rep.
[AT&T Samsung Galaxy S II SGH-I777] kirdroid:
I called them to add the 4G plan and now it is showing

GPRS MB WAP/BBRY/ISP 2GB DOM $10.00/1GB ADDL - HSSMT2GBH

Does anyone know what this HSSMT2GBH is and if it is the right one?

I told them it should be HSDPPB, and they are saying the one i'm having is indeed a 4G plan and i dont have change anything.

I'm getting terrible speeds 0.5 - 1 Mbps download and 0.5 Mbps upload :(
[AT&T Samsung Galaxy S II SGH-I777] juicedog:
That looks like a 2GB limited plan... not unlimited. If you had an unlimited plan before, call AT&T right away and get the unlimited plan back.
[AT&T Samsung Galaxy S II SGH-I777] bclark:
I stopped in to see an acquaintance who works at ATT and asked him to switch the phone on my acct to my Inspire. He does it and proceedes to tell me my Captivate is still the phone attached to the acct even though I haven't used it in almost two months. I asked him about IMEI sweeps, He then tells me that they never happen. 2 days later a dumb phone is attached to my acct from an IMEI sweep??? Mmm ATT is awesome. He changed my email to something other than mine too?

I still have an unlimited plan though!!
[AT&T Samsung Galaxy S II SGH-I777] kirdroid:
Hey I just switched to ATT so i dont have the unlimited plan. I'm only worried if they have the right 4G plan on my account.
[AT&T Samsung Galaxy S II SGH-I777] VJKotts:
The rep on the phone could not help me, so now I need to go back to the original settings. I forgot to write them down. Does anyone know what the original APN was?
[AT&T Samsung Galaxy S II SGH-I777] rwj5279955:
There is APN chooser apps on the market. Assuming you have data. I don't want to quote you the wrong settings.
[AT&T Samsung Galaxy S II SGH-I777] aimfire72:
In the APN section, hit the bottom menu button an choose "Reset to default" to go back to the stock settings. Worked for me.
[AT&T Samsung Galaxy S II SGH-I777] juicedog:
So frustrating.

I spent an hour at the at&t store yesterday doing a side by side speed test against the infuse 4g demo unit vs my gs2. I tried every single apn combo that I found on my gs2, but the infuse came out ahead every single time... most of time twice as fast. Btw, I'm on the 4g unlimited plan.

I don't know what else to do at this point. So I'm back to the default apn settings. For me, the default settings work most consistently. No offense to the OP, but his settings don't work well in San Francisco and mms doesn't work at all for me.

If anyone else has a better luck with their apn settings and 4g speed, please let me know the settings that you are using.
[AT&T Samsung Galaxy S II SGH-I777] kirdroid:
Same here, am on the limited 2gb 4g plan and tried all possible apn settings but speeds are way low compared to the att 4g devices :-(
[AT&T Samsung Galaxy S II SGH-I777] mchimney:
Eveything was working but now mms has stopped
[AT&T Samsung Galaxy S II SGH-I777] VJKotts:
Thanks for the help figuring out the APN?

What should I say to the ATT rep (in simple terms) to make him understand that I want the 4G plan enabled on my phone? I just couldn't get my point across to him.
[AT&T Samsung Galaxy S II SGH-I777] daraj:
People its the

radio

along with the correct APN settings and correct account configurations- not the APN settings alone. :rolleyes:
[AT&T Samsung Galaxy S II SGH-I777] kirdroid:
Anyone know if csc, pda versions matters for USA?

My wife's phone is stock and her pda is Ke7, csc is kd1. I flashed litening rom 1.3 and my pda is ke8 and csc is kd2.

I'm not having any issues currently, but want to make sure I understand what these various versions mean?
[AT&T Samsung Galaxy S II SGH-I777] juicedog:
Daraj, so are you implying that you do see the benefit of using op's apn settings and being on the 4g plan? Which radio are you referring? Please do share the details.

I for one am on the 4g unlimited plan AND have tried various apn settings with no improved result in San Francisco. I'm on stock radio.
[AT&T Samsung Galaxy S II SGH-I777] rwj5279955:
When the U.S. versions start rolling out, we should (granted same radio hardware) be able to flash different modems to optimize network speed and reliability. Just like we did with the SGS.
[AT&T Samsung Galaxy S II SGH-I777] daraj:
No. What im saying is that our radio is not optimised for at&t like that of the inspire or the infuse. No matter what apn we use we wilk not get the correct speeds unless we have the correct optimsed radio. wait till the US hits and u will see speed diff
[AT&T Samsung Galaxy S II SGH-I777] kirdroid:
So once we get the us release, we just flash the us radio and we are all set or is it a more complicated process?
[AT&T Samsung Galaxy S II SGH-I777] lpsi2000:
I don't know about that one, I was getting better download speed with Captivate when I was using EU Radio instead of the US Radio. Also right now with my SGS II, I am getting the same speed as the Atrix and sometime even better. The only issue I have is MMS. MMS does not seems to work for me at all. If I put my SIM on the Atrix, MMS works just fine.
[AT&T Samsung Galaxy S II SGH-I777] locust43:
The APN setting's have a lot to do with it and in most cases do help a bit. But the radio software may also have something to do with it, and the fact is AT&T isn't really known for having a great network so speed's are often slow because AT&T doesn't really even have a "4G" network, and their HSPA+ underperforms most other carrier's equivalent.

AT&T only has backhaul for this technology rolled out in a select few places anyways.
[AT&T Samsung Galaxy S II SGH-I777] dmunjal:
Just got my S2. Changed the APN, went to the AT&T store, changed plan to 4G using a display Infuse IMEI and immediately noticed speed change to over 4Mbps. This is in SF.
[AT&T Samsung Galaxy S II SGH-I777] rwj5279955:
The APN will have more to do with what route the radio takes to use the network. If the U.S. versions have compatible modems, in my opinion we should be able to pick and choose what works for our areas.

I got speeds on my Captivate comparable if not slightly faster than my SGS2. Using I9000 modems.
[AT&T Samsung Galaxy S II SGH-I777] daraj:
I agree, but for the only reason, that AT&T capped/crippled the upload/download speed for the Captivate' radio so they dont shoke the network. Its Optimized!! With the EU radio the cap is removed and thats why you saw speed gains. Now that AT&T is rolling 4G and upgrading its speed, we are seeing faster and faster speed on its 4G devices like the Infuse/Inspire. My belief is that we will see the correct network speeds when the US SGS2 hits the streets.... provided AT&T doesnt cripple it like it used to :(:(
[AT&T Samsung Galaxy S II SGH-I777] ryan24:
has anyone figured out the correct mms settings? i've tried the OP's suggestion and also the one on page 6, but neither worked. I've also tried a few from some google searches.
[AT&T Samsung Galaxy S II SGH-I777] lpsi2000:
Exactly my point, and it seems the EU modem will also play an interesting role here too for the US
[AT&T Samsung Galaxy S II SGH-I777] lpsi2000:
Agreed, providing AT&T... which we know they will.:D
[AT&T Samsung Galaxy S II SGH-I777] lpsi2000:
MMS has not worked for me ever since I got my SGS II. I don't know yet what it is but as soon as I move my SIM to the Atrix MMS seems to work fine. I am thinking it might have something to IMEI #. Considering the fact AT&T does not have it on file.
[AT&T Samsung Galaxy S II SGH-I777] c19932:
guys please help. my internet keeps dropping to EDGE and stays there! 1 out of 10 times when I restart my phone, 3g/H+ would work for a while, then drop back to edge again.
[AT&T Samsung Galaxy S II SGH-I777] rwj5279955:
Check your inbox.
[AT&T Samsung Galaxy S II SGH-I777] ronj1986:
Have you tried going to messages, galloping menu, settings? Is your mms set to auto retrieve? Also is this the # listed in your message centre box?
[AT&T Samsung Galaxy S II SGH-I777] zevrosenthal:
I am also unable to get MMS on my SGII. I've set the MMS settings per the first post in the thread (see below), went into messaging, settings and confirmed "auto-retrieve" is checked. The message centre number I have is +13123149810.

Perhaps someone can direct me in the right direction? Regular SMS works fine; just no MMS.

Data connection also works great - no problem getting good H+ connections (I'm in New York City)

PS: Like the previous post, I also have an ATRIX and, have no problems getting MMS on the Atrix if i move the SIM over.

Step 2 : MMS Settings

At the APN settings hit the menu key again and create a new APN, call it MMS

Under APN again just type : phone

go down to MMSC and fill the fields as follows

MMSC: http://mmsc.cingular.com

MMS Proxy: wireless.cingular.com

MMS Port: 80

MCC: 310

MNC: 410
