I'm finally seeing a big jump in dl speeds. Since June, I couldn't Ger above 1900kb, and suddenly within the last week I got back up to 3's 4's, and last night a 6500 and a 6600. I swear they released more bandwidth, device specific when the AT&T version released.
[AT&T Samsung Galaxy S II SGH-I777] lgkahn:
no speed increase here says h+ but still getting aroudn 1-2 down and 1 meg up on non feature phone 3g family unlimted plan
[AT&T Samsung Galaxy S II SGH-I777] dberube:
Over the summer I bought a Euro version of the SGS2.

I called AT&T to have them change my data plan to the HSPA one, using the SOC code.

They told me that the device's IMEI shows up in their system as an Unknown Unlocked Device from an Unknown manufacturer.

I spoke with numerous people from AT&T and they say there is absolutely no way to add the HSPA plan to this device because their system doesn't recognize it as a "4G" phone.

Anyone else have this problem and get around it??
[AT&T Samsung Galaxy S II SGH-I777] 02ranger:
You have to get an IMEI number from an ATT 4G phone and give them that number as the phone on your plan. There are LOTS of discussions on this earlier in this thread on options for getting a number.
[AT&T Samsung Galaxy S II SGH-I777] 02ranger:
Another question. What modem is everybody using on AT&T's network? I'm on kh5 now and its OK, but I'd love to hear everybody's opinion on this.
[AT&T Samsung Galaxy S II SGH-I777] dberube:
I'm sorry, I should have done a more thorough search first.

This did work for me and I'm not able to connect to the new APN.

However, I did tether my Mac and it still shows AT&T GLOBAL NETWORK.

Does this mean it didn't work, or that I'm not in an HSPA area and it reverted back to 3G?
[AT&T Samsung Galaxy S II SGH-I777] 02ranger:
I wasn't trying to be rude or a jerk, just saying there are lots of options. So you did get the code added? The way I could tell I was on the right network was in the speedtest.net app. Go to tools once it selects a server and look at your external IP address. If it starts with 198 then I think you're connecting right. The only way I could get a 198 address consistently was with the APNs I listed above after flashing the Touch X-Power ROM. Try those if nothing else is working. If you're getting a 32 or 166 (?) Address then you're still connecting by the old gateway. I didn't ever understand the ISP thing.
[AT&T Samsung Galaxy S II SGH-I777] dberube:
You weren't being rude or a jerk and it didn't come off that way either.

I personally find it a bit irritating when people don't do a little research for themselves first -- so I was disappointed in myself.

I am connecting with an IP of 32.167.XXX.XXX

I deleted the original/old APN and all I have listed in my APNs now is the HSPA and the MMS.

Could I be connecting to the old gateway because I'm not in an HSPA area? (on their coverage map, I'm about a mile in on the 4G side of the 4G/3G edge)

Before I called and added the 4G data to my phone, I couldn't even connect to the new APN -- so it's allowing me to connect to it now which makes me think it is working.

What do you guys think?
[AT&T Samsung Galaxy S II SGH-I777] 02ranger:
Sounds to me like its still connecting via old gateways. I'm in a 3g only area and still getting a 198 address. I noticed a speed increase when I started getting a 198 address, albeit a small increase. Try the apns I posted earlier. Its a few posts back. Posted them yesterday I think. That's what did it for me. I don't know what kind of speeds you'll see but you should see some increase on a 198 IP as I understand it. Its possible I don't really understand it all like I think I do either. :)
[AT&T Samsung Galaxy S II SGH-I777] dberube:
I tried yours earlier.

I'm using CM7, so you have to manually type in APN type, and when you type in "internet" it just flat out doesn't work.

It will only work if you use "default".

I added your BROADBAND APN and my IP changed to 166.XXX and speedtest is now showing 4.5mbs whereas on the 32.XXX IP I was only getting around 2mbs...

So not too sure what's going on.
[AT&T Samsung Galaxy S II SGH-I777] kinubic:
any answer to this? i did chat with csr they said that its 4g but no where on my account does itshkw if its 4G or soc?
[AT&T Samsung Galaxy S II SGH-I777] 02ranger:
I don't know what's going on with it. All I know to do is keep trying different APNs. Have you gone on the AT&T website to make sure you have the new SOC code on your account? That's the only other thing I can think to try. Make sure you're rebooting after APN changes if you haven't been already. Sorry I can't be more help.

Edit: When I was on cm7 I never could get it to work either. It wasn't until I flashed a samsung-based ROM that I got some better results.
[AT&T Samsung Galaxy S II SGH-I777] Jade Eyed Wolf:
I don't know if it's just my SGS2 or not (bearing in mind, we're talking about the international one here, not the AT&T branded one), but the only 3 options I have for APN Type are MMC, Internet, or Internet + MMC. I'm not seeing dun, or supl... Where are you getting that? Are you using the international SGS2? Or is this possibly in the AT&T version?
[AT&T Samsung Galaxy S II SGH-I777] 02ranger:
This is the international version. I had those APNs when I first flashed the Touch X-Power ROM. I've never seen dun either but I have seen supl somewhere. The broadband APN is grayed out so I can't make changes to it. If you want, I can copy my apns-conf file and send it to you. It may tell you something about where those options came from. You may be able to flash that ROM and see if it gives you the same APNs.
[AT&T Samsung Galaxy S II SGH-I777] Jade Eyed Wolf:
Nah, that's ok. I was mainly just curious. I've got the 198.x APN working on my phone just fine right now anyway.
[AT&T Samsung Galaxy S II SGH-I777] dberube:
Anyone else not able to get on the 198.x IP using the APNs described in this thread exactly?

I'm on the international S2 using CM7 nightlies with no luck!

I 100% am on the HSPA plan, the code is listed in my account.
[AT&T Samsung Galaxy S II SGH-I777] dmunjal:
I've gotten 32.x and 64.x but never 198.x.
[AT&T Samsung Galaxy S II SGH-I777] amaffey:
Do you have to be rooted to do this? Because I can't delete my APN's

[AT&T Samsung Galaxy S II SGH-I777] 02ranger:
When i was on cm7 i finally got decent (for me) speeds and a 198 address. I had to type in default for apn type on the phone apn. It doesn't work with internet in apn type. I did both apns and deleted the one already there. Then i restarted. It worked after that but i noticed my internet connection would come and go all the time.
[AT&T Samsung Galaxy S II SGH-I777] kinubic:
using the default APN and so far i get

DL 2800kbits/s

UL 2000kbits/s

this is on extreme labs

speedtest differs

DL 1800 kbps

UL 1105 kbps

lol
[AT&T Samsung Galaxy S II SGH-I777] jdsemler:
Tried some of the suggested settings in this thread, even the front page, but I am having no luck.

I am running cm7 nightly build 80 and only seem to get the old wap.Cingular apn to work.

Anyone found apn settings that work for hspa+ at&t? I do have the 4g smartphone plan thanks to an infuse 4g imei
[AT&T Samsung Galaxy S II SGH-I777] Jade Eyed Wolf:
Can you post a screenshot of the APN settings you're trying to get HSPA+ to work on?
[AT&T Samsung Galaxy S II SGH-I777] robsw:
Just checking - are you really not getting H+ or are you just not getting the H+ symbol in the notification bar? CM7 doesn't have the H+ symbol but you still can get H+ speeds, even though it only says H.
[AT&T Samsung Galaxy S II SGH-I777] Jade Eyed Wolf:
That, and as mentioned earlier in this thread, the surest way to check is by noting the IP address you have when you perform speed tests. If you're getting a 198.x.x.x address, then you're all set!
[AT&T Samsung Galaxy S II SGH-I777] jdsemler:
I was getting no data at all, unless I used the old wap.cingular with the old login/password credentials.

I ended up using this app, which seems to have set things up, though it isn't breaking any speed records. It is on the 166.* address.

It added the following:

Name: Tweakker

APN: phone

MCC: 310

MNC: 410

APN type: default,supl

APN protocol: IPv4

(everything else is <Not set>)

Name: Tweakker - MMS

APN: wap.cingular

MMS proxy: 66.209.11.32

MMS port: 80

MCC 310

MNC: 410

APN type: default,mms

APN protocol: IPv4

(everything else is <Not set>)
[AT&T Samsung Galaxy S II SGH-I777] Jade Eyed Wolf:
Not sure why you not still picking up the new APN.

No 198.x.x.x address = Not the new network

Any other IP address, and you're still stuck on the old network. (Usually 32.x.x.x or 166.x.x.x)

Now here's the thing, and I think I mentioned this earlier too, any time you send or receive a picture/video/sound message, the device has to disconnect from the new APN (assuming it was already connected) and then reconnect to the old APN to receive the MMS. Once it has done that, it will be "stuck" on the old APN until you have rebooted and made sure that you have connected to the new APN as soon as you boot back up.

Reboot, and try connecting to the new APN.

Have you tried this yet?
[AT&T Samsung Galaxy S II SGH-I777] Micronads:
I called at&t and they switched my imei number to one off of my friends galaxy s2 at&t edition. I am connecting on the 166 ip address now, was on the 32 address before. My speeds have gone up over 10 times what they were before. Not sure if the 196 ip is available in Kansas City. Before the imei change I had to use wap.cingular for the access point name, now I can use "phone". So it seems like I am on the high speed network but I am not getting the right ip.
[AT&T Samsung Galaxy S II SGH-I777] Jade Eyed Wolf:
Hmm, news to me. I'll make a note of that. I have occasionally seen the 166 address show up for me while I'm using my laptop connect SIM. Interesting...
[AT&T Samsung Galaxy S II SGH-I777] Jade Eyed Wolf:
So, having fiddled around a bit and doing a little more homework, this is what I have been able to deduce myself:

There are a total of 4 APN's that are publicly available to most people from AT&T as far as I can tell:

Phone, Broadband, wap.cingular, and isp.cingular.

Both "Phone" and "Broadband" are AT&T's newest APN's and yield a 198.x.x.x IP addresses. As far as backhaul is concerned (and thus user experienced network speeds), they both appear to utilize the new backhaul, so you should get the fastest speeds using either of these APN's. The only real differences between the two, as far as I can tell, are administrative only (basically, they determine whether or not you can tether). So, for instance, if you have an old Smartphone Unlimited plan (but no tethering option) with the HSDPB SOC code, you'll only be able to connect to the "Phone" and "wap.cingular" APN's. If, however, you DO have a tethering plan on your account, you will also be able to connect to the "Broadband" and "isp.cingular" APN's. The only way I personally was able to connect to either the "isp.cingular" or "Broadband" APN's, was if I swapped out my data-only SIM card (because my smartphone SIM doesn't have the tethering option).

So, to break it down:

"Phone" and "Broadband" APN's are the newest and thus fastest APN's to connect to and should give you 198.x.x.x IP's

"isp.cingular" is on the old backhaul and designed for mobile broadband/laptop connect cards, and should yield a 166.x.x.x IP. Also, this APN no longer requires a username or password to connect.

"wap.cingular" is also on the old backhaul, but designed for phones only and should yield a 32.x.x.x IP. Just like "isp.cingular," this APN also no longer requires a username or password.
[AT&T Samsung Galaxy S II SGH-I777] [SMAN]:
So i went into an AT&T store today to compare my SGS2 world edition vs the one they were selling. I verified that my APN matched the one in the phone (it was set to phone). I ran the speedtest app on both phones and got a very similar speed (about 2.5 down 1 up) and they both yielded a 166 IP. So i'm thinking that maybe the 198 network is just not available here yet.
[AT&T Samsung Galaxy S II SGH-I777] Jade Eyed Wolf:
Hmm, that's interesting... I suppose that theory has some traction.
[AT&T Samsung Galaxy S II SGH-I777] tbong777:
This is intersting as I chose the old UL data plan using Cingular 410 whihc is the only APN that works in that mode. Does this increase speeds or is it the same?

All three ATT choices stated "Something is wrong" after running Hmmm

Tried to set that up manually but the "red" lines are not available on my device.
[AT&T Samsung Galaxy S II SGH-I777] 3waygeek:
Over lunch Monday, I went to my local AT&T store & asked to be upgraded from the old $30/month 3G smartphone personal plan (DPPB) to the 4G plan (HSDPPB). I had the IMEI from an Infuse 4G handy, since my SGS2 isn't the AT&T version.

I didn't need the Infuse's IMEI -- they were able to update me without it. I guess that they either changed their systems to not require an IMEI, or now that they sell their own SGS2, they recognize all SGS2 IMEIs, not just their own. It was a very smooth process; once I got to see an agent, the update took about 3 minutes.

Having converted my plan, I did see a speed increase of around 25%. I got up to 9.18 Mbps download speed last night, on a UMTS conncetion via the HSPA+ APN on the 166.x.x.x network. Prior to the plan change, the highest speed I'd seen was 7.25 Mbps.

I'm using the AT&T HSPA+ APN, which seems to work more reliably now that I've changed my data plan. Prior to the change, I could only connect to that APN sporadically, and would often have to fall back to the Cingular APN. I've tried the broadband APN, but have never gotten a connection with it -- that may be because I can't set the APN type to dun. The only choices available to me are internet+MMS, internet, and MMS.

Over the last 5+ months I've had the SGS2, I've done about 25 speed tests, getting an average speed of around 5.5 Mbps. All tests were done either at my home or office, about 10 miles apart. Connections were mostly by UMTS, but occasionally HSPA. Roughly half were on the 166.x.x.x network, the rest were on the 32.x.x.x.x net. I've never been able to connect to the 198.x.x.x network, which may not be implemented yet in my part of Atlanta, or it may be because of the aformentioned problems with the broadband APN.

Well, learned my lesson of "if it aint broken..don't mess with it" i flashed a new ROM and now i have no connections..my data is "GPRS WAP UNLTD DOM - DPPB" any ideas? None of the default APN's work..along with the ones in OP.

Oh, and i recently went by AT&T and mentioned updating it to 4G data plan..and they gave me a new "4G" sim card..lol

having a similar problem with cm7, im on the i777 though. Cm7 settings default to cingular wap, but vanilla rom defaults to the two at the beginning of the thread. However, if I try to set it as phone while using cm7, i can't get a data connection.
[AT&T Samsung Galaxy S II SGH-I777] dwaleke:
I tried the settings in the first post and have sporadic data connection afterward. When I do have a connection the speeds are not very good at all.

Sticking with wap.cingular seems to be the only option for me right now. I am able to hit 7-8Mbps download and 1.5 Mbps upload in certain areas, but never usually get above 2/.7Mbps. I usually get a 32.x IP address with this APN.

With the "phone" apn in this post I can never get above 2.5Mbps assuming I get a connection at all (web pages error during loading ,etc). I usually get a 198.x IP address with this APN.

I am located in Detroit Michigan and have tested in the surrounding area as well. I guess it's possible that the 4G APN is not fully implemented in this area.

UPDATE:

I flashed my phone back to stock to see what the default APN values were. I also contacted AT&T and had them verify my data plan and they said they pushed something to my phone. Flashed my custom rom back and ran some tests. Now in places where i was only getting 1.5Mbps (poor signal areas) I'm seeing 3-4Mbps. And data connection is consistent - pages load correctly without error unlike before. I need to go outside to where I get good signal and see what my speeds look like.

Here are the AT&T original APN values on my S2. I've seen variations of these posted all around, but figured I'd post what my phone shipped with:

Name: ATT PHONE

APN: Phone

APN: wap.cingular

MCC: 310

MNC: 410

Authentication type: None

APN type: mms,supl

Update2:

I was able to hit 8Mbps all evening at home. I was able to hit 15Mbps in the middle of the night. So looks like I have HSPA+ with the backhaul in my area. Too bad I only get those speeds in the middle of the night. Oh and I always have a 166.x IP address in speed tests.
[AT&T Samsung Galaxy S II SGH-I777] SoCaliTrojan:
is going to an at&t store the only option? I've contacted at&t 4 times and they said that they can't see the soc code hssppb. they say I have 4g here and my average of 0.80 is 4g speed.

I'm trying to avoid the store since I'm rooted with a custom ROM. I've replaced everything that was stock...
[AT&T Samsung Galaxy S II SGH-I777] 3waygeek:
You shouldn't have any problem with your rooted custom ROM -- when I went there to upgrade my data plan, I was running CWM and the KI3 kernel. They didn't even turn on the screen; they just opened the back to see that I had a current SIM card and read the IMEI off the label.

does this mean that 0.80 Mbps is a normal speed for an at&t gs2?

I was thinking that maybe my grandfathered data plan is 3g and needs to be switched to unlimited 4g. I upgraded through Best Buy.
[AT&T Samsung Galaxy S II SGH-I777] Jade Eyed Wolf:
Your speed is dependent upon many different factors. I have a grandfathered unlimited plan myself, so my recommendation on that one would be that you hold onto yours as if your life depended on it!

Depending on where I am, my speed has been as low as .1MBit (in a shopping centre right next to an airport in DC, where MANY people are competing for the same bandwidth) and as high as 9MBit (during weekends when no one else is in the office building where I work, and the internal repeaters are fed by 6 T1 lines for service).

Try to picture how many people in your area are within an approximately 1km radius. Now, take that number and cut it roughly in half (a little less than half of Americans are on AT&T). Now, of that number of people, picture roughly 85% of them as having some sort of apple or android device, and they're all checking their Facebook and YouTube. Oh, and you're all sharing the same internet connection. Now does your speed suckage make sense?
[AT&T Samsung Galaxy S II SGH-I777] SoCaliTrojan:

I777 and ****rocket users shouldn't be screwing with their APNs, these devices came with correct APN settings. ****rocket users shouldn't even be here, as their phone has nothing at all to do with the I9100. It's not like the I777 that has 95% commonality.

Actually if you had the "****" rocket then you WOULD know that data with it right now is very problematic in a sense that we have very slow and sometimes inexistent internet at all.

And with the apn settings used in here a lot of us were able to get much higher data speeds.

Which for the most part solved our problems.

I'm a little embarrassed that I haven't been able to figure this out by looking through the thread...

I am NOT grandfathered in to unlimited data. Is the HSDPPB soc code still what I want?

The reason I ask is this- I called at&t and used an imei from an Atrix. Now my plan says "DataPro 2 GB for Smartphones on 4G", but my soc code is "HSSMT7", not HSDPPB.

I am connecting on the 166 server, not the 198, with the new apns :( I'm assuming that's because I'm not on the right plan.?.?. Can I still change to the HSDPPB soc if I don't have unlimited?
