yep, I just did a re-install and flashed it from a frankenstein ROM to cyanaganmod nightly and same diff, its fixed. So now I just need to convince AT&T to do the HSDPPB code correctly, so I can get the phone APN working correctly. Would love my HSPA+ on.

Tell me does anyone have the Atrix 4G or another AT&T HSPA+ phone and know if the HSDPPB SOC code is the same unlimited 4G data as the others? Might be easiest to say you have a 4G phone like the Atrix, but after a bit of research online, you find out the issue is linked to them not having set-up the right data plan when ya upgraded without the subsidy.
[AT&T Samsung Galaxy S II SGH-I777] r34p3rex:
When I got my Inspire 4G at the store, they switched my unlimited ($30/mo) to a 4G 2GB plan. They told me I would need to call 611 and tell them that I wanted to be put back on the unlimited plan with the 4G active. When I called, the rep told me they would file a case on my behalf (to be approved by a manager or something) since they (Customer Service) no longer had the ability to add unlimited data plans. A few days later, they texted me letting me know I now have unlimited 4G data :D
[AT&T Samsung Galaxy S II SGH-I777] Docsboard:
can you kindly post yoru settings?
[AT&T Samsung Galaxy S II SGH-I777] [SMAN]:
So i picked up the SGS2 from expansys-usa and put it on at&t. And just like most of you, it wouldn't regnize the "phone" APN and only recognized the "wap.cingular" APN. Reading though this, it's probably because i HSDPPB SOC code put on my account. When i called tech support, they said the system would not let them add it to my account because my IMEI is not being recognized as a 4G capabale phone in the system. So does anyone know what i do in this sort of case? I'm waiting for a call back from escalation, but i'm stuck on 3G speeds until then.
[AT&T Samsung Galaxy S II SGH-I777] gspears:
You have to call them back with an IMEI from a 4g capable phone. Then they can switch you. I think they are the Infuse and others. If you go into a real AT&T store you can ask them to use a display phone's IMEI to do it. Or, some have had luck with Google.

I just have the 10 buck plan and have had data up to 7 down and 2.5 up. Let me know what speeds you get after they get you on the 4G plan. I still have not had anybody let me know if it's worth the upgrade cost.
[AT&T Samsung Galaxy S II SGH-I777] [SMAN]:
Ok that worked and they were able to give me the unlimited 4G plan and i switched my APN over, but i'm still getting 2MB down 1MB up despite being on H+ with full signal.
[AT&T Samsung Galaxy S II SGH-I777] kirdroid:
That is why just use the $15 unlimited data plan, you still get same speeds and unlimited data, plus save some money.
[AT&T Samsung Galaxy S II SGH-I777] Illicit Hero:
this is a slower one too.
[AT&T Samsung Galaxy S II SGH-I777] [SMAN]:
What are you doing to test that? Just running speedtest.net on your phone?

EDIT:

Seems to be going a little faster, but no where near the numbers that have been posted here. Maybe it's my Modem cause i'm on KG6?
[AT&T Samsung Galaxy S II SGH-I777] tbong777:
Same here..Its plenty fast for the little phone data I actually use,,,,Mostly WiFi anyway, just don;t have to monitor data anymore nor be afraid to download the occasional app over 3G

Has anyone tried this? (make sure you guys make a backup) :)

http://xdaforums.com/showthread.php?t=1087729

Method 1:

Note that for Method 1 you need to have installed Root Explorer.

1. adb pull /system/build.prop (this is not essential but just required to make a backup copy)

2. Launch Root Explorer on the phone

3. open /system folder and click on "mount r/w" option

4. open the build.prop file on Root Explorer (to edit the file)

5. Add following code to the end of the file:

ro.ril.enable.dtm=1

ro.ril.gprsclass=12

ro.ril.enable.3g.prefix=1

ro.ril.hsdpa.category=28

ro.ril.hsupa.category=9

ro.ril.hsxpa=3

6. Save and quit Root Explorer

7. Reboot your phone and enjoy!

I'm on the $10 at&t non-smartphone data plan and it seems to have improved my average speed (Im now seeing dl speeds in the 4-7mb), but I still get dl speeds in the 1-2mb once in a while.
[AT&T Samsung Galaxy S II SGH-I777] BigE:
For once and for all -

1. AT&T do not have LTE technology deployed (yet)

2. Results vary from 1M to 9.1Mbit/sec on their current HSPA network. (D/L)

3. The phone is capable to up to 21Mbit/sec but the network, anywhere, does not have it.

4. speed vary by distance from tower and sharing bandwidth with other users. The further the tower is, and the more users connecting to it, the slower it gets.

5. It looks like some other models gets better results. It is not in the hardware, and unlikely it can improve by code. I suspect AT&T prioritize it to IEMI they own/sold. Since our phones are not theirs, if they run bandwidth limits by IEMI, we will see better performance on the Inspire/Infuse/Iphones.

6. Being on the $10 plan is a financial cheat, no more. Enjoy it until AT&T will find out.. By contract they deserve $25 for a smart phone.

I do visit this thread from time to time, and I do run speed tests weekly, only to see nothing new.

:cool:
[AT&T Samsung Galaxy S II SGH-I777] gspears:
This is crap. At&t KNOWS that I am on an SGS2 and CHOOSE to charge only 10 dollars per month. I am NOT hiding anything from them nor am CHEATING them in any way. I told the CSR I spoke with exactly what kind and type of phone I have and they put me on the 10 dollar plan. If they want to change it then that's up to them.

And BTW, I checked speeds at work and am still getting around 6.5 down and 2.25 up on KH3, so no changes.
[AT&T Samsung Galaxy S II SGH-I777] BigE:
yep, I know they know, and I know currently they do nothing. For over 3 years I did the same, being on a $10 plan too. However, the contract allows them to change it to 25 if they wish too. When I said 'cheat' I did not mean people take false play, but that the system (and 99% of AT&T's service people) don't quite understand/know how to handle this. My guess is in time, they will run a code that will identify usage/speed vs. plans and deal with it. Enjoy the lower rate while it lasts..

I really hope they will deploy and run LTE soon

I am on KH3 as well, and get speeds ranging from 2M to 8M (but the 8M is spotty and drops) . Was in Santa Monica, CA recently and could not get even 0.5M there .. So it is all network/capacity related, not our phone..
[AT&T Samsung Galaxy S II SGH-I777] bbgt2:
Thats because usually the "tech" on the other line is nothing more than a Wal Mart greeter reject and all they can do is read of a screen.

If you have a technical issue you have to walk to a ATT owned retail store, those guys have always helped me.

I tried to get my data switched to 4G with a "tech" over the phone (took a chance) and the guy was lost simply lost when I asked him to do what I asked and thats after I explained to him 4 times why I wanted him to do that.

He actually said "what kind of phone is a samsung sgs II"

After that, I said dont change anything clear your screen and make sure you are not on my account anymore.

Going to a retail store tomorrow to get them to change it.

Hey all - I'm a former iPhone user and have had the GSII for about a month now. I'm currently running on my grandfathered 3G unlimited plan. From what I understand in order to access the real "4G" speeds, I must tell AT&T to put my phone on an AT&T 4G imei? And then once that is done I will change the pan settings? Thanks all - wap.cingular is horrendously slow - about 1mbs for me in areas I have gotten 4mbs on an iPhone. Also I already called AT&T and the guy told me he can't put an imei on a phone that's not part of AT&T, and he would have to see it in person to check it out anyways. Is there a way past this? Thanks all

And let us know if it actually makes any difference. I still get 6.5 down and 2.25 up regularly at work on my 10 dollar dumb phone plan.

One thing that might be different is that I'm in AZ. I know AT&Ts network here is not very well developed so they might just dump everybody in the same network whereas in other places they might actually have different networks for 4G. I've still never seen any evidence of it.

I'm waiting to hear someone say they had the dumb phone plan getting 6 to 7 down, then changed to the 4G plan and now they are getting 10-12 down, but no such luck. So I still don't believe there is a difference.

Show him the phone. Just tell him from the beginning that you have an SGS 2 but want to be on the 4G plan and ask him to please use one of the IEMIs from one of his display 4G phones.

Quick question once you have the 4G plan, can you use a 3G only phone on this plan in case one needed to use a spare old 3G phone while the 4G phone is repaired.

Thanks
[AT&T Samsung Galaxy S II SGH-I777] gspears:
I'm not convinced that there are really different networks for 4G and 3G. A lot depends on where you live. In any event, your phone determines which network you'll access based on the APN. On most of the older phones, the APN is programmed from the factory so it will access the net as it always did. The fact that you're on a 4G plan doesn't affect whether or not you can still use older phones at lower speeds.

hello everyone I have a problem and need some advice at least from people with knowledge not like the people from att :(

my problem is that i recently bought a SGS2 from newegg and as soon as I received it I start using it with my att sim card but I did notice that I was not able to connect to the 3g,4g network not even Edge. So I decided to try the phone with the sim card of my wife which's she has a iphone 4.... and just after booting the phone the network was working great with up to 10mbps down out of the box.....

so I contact att they could't help because my device is unlock and they dont do support for those kind of phones.....

here are some faqs I could notice

-both my wife and I have the same data plan

-the APN which was set automactly are correct

-my wife's SIM card is diferent then mine she is micro mine is normal

-my simcard says 3g on the logo the same as my wifes sim.... but mine is a bit older

could it be because my SIM card is outdated ? or could it be anything else ?

thanks for your help guys
[AT&T Samsung Galaxy S II SGH-I777] Illicit Hero:
Get a new sim card from a corporate owned AT&T store. Get an IMEI number from a AT&T 4G device from a display unit or Google. You can either then try your luck with a Rep in person or over the phone. Use the IMEI number to register for 4G.

You should really search or read this thread at all.

[AT&T Samsung Galaxy S II SGH-I777] Jade Eyed Wolf:
Here's a scenario: Imagine you're at someone's house with a laptop. Now imagine that person, for whatever crazy reason or another, has two WiFi routers: one which is connected to a DSL line, the other connected to a really fast cable modem or FiOS. Both WiFi routers are the same, and you connect to them using the same wireless technology, with the same theoretical speeds and limitations. However, it's likely that the AP connected to the cable modem/FiOS is going to be noticeably faster than the other AP connected to the DSL line because cable/FiOS is a much better backplane.

From the standpoint of the wireless technology used between the tower and your device, yes, you are correct; there is no difference. The differences happen inside AT&T's backplane. If you notice your IP address when you perform your speed tests, it will be either a 166.x.x.x or 32.x.x.x address if you are connecting to the old APN, and it will show up as a 198.x.x.x address if you are on the new APN.

Ok, so my IP is different. So what? What does that mean?

Well, simply put, the new 198.x.x.x network has been designed from the ground up with the sole purpose of supporting the huge amounts of data throughput that the latest HSPA and LTE networks demand. Internal routing is faster and more efficient, trunk links are wider, and the equipment is all new. In the end, all those factors add up to making your experience potentially a lot faster when connecting to the new APN instead of the old one.

That said, if you're in an area where there are a LOT of other heavy data users (like where I am), you may not notice much of a difference simply because of how many other people are competing for access to your tower. My ping times are consistently about 40 - 60 ms faster though ;)
[AT&T Samsung Galaxy S II SGH-I777] [SMAN]:
What your saying there makes a lot of sense. So now if i'm on the "Phone" APN and i still have a 166 IP adress, does that mean they haven't implemented the faster speeds in my area or is there something else up with my phone?
[AT&T Samsung Galaxy S II SGH-I777] Jade Eyed Wolf:
Something must be wrong. If you're not getting a 198 address, then you're not on the new APN. Have you made sure that you have the correct account plan as mentioned in the OP?

(1. HSPA+ 4G 2GB plan OR for Unlimited Customer's

2. Smartphone Personal Data plan with 4G SOC code : HSDPPB)

It should be mentioned that, even if you have a grandfathered unlimited plan, you still need to ensure that you have the HSDPPB SOC code. Mine didn't work until I had that code on my account.

Another thing that I have noticed is that when switching between APN's in the settings, sometimes it doesn't "take" and just defaults back to the old APN. It seems this happens whenever you send/receive MMS. For some reason or another, sending and receiving MMS only works via the old APN, and in order to do that, the phone disconnects from the new one, and then reconnects to the old one. That said, once that has happened, it stays on the old APN until you reboot and set it to the new one...

Hassle isn't it?

Anyway, assuming you have the correct SOC code on your account as mentioned above and in the OP, try this. These are my settings:

You need two APN's configured.

The default/old APN:

Name: Cingular 410

APN: wap.cingular

Proxy: wireless.cingular.com

Port: 80

Username: WAP@CINGULARGPRS.COM

Password: CINGULAR1

Server: cingulargprs.com

MMSC: http://mmsc.cingular.com/

MMS proxy: wireless.cingular.com

MMS port: 80

MCC: 310

MNC: 410

Authentication type: <not set>

APN type: internet + mms

New HSPA+ APN:

Name: (Whatever you want to call it)

APN: Phone

Proxy: <not set>

Port: <not set>

Username: <not set>

Password: <not set>

Server: <not set>

MMSC: <not set>

MMS proxy: <not set>

MMS port: <not set>

MCC: 310

MNC: 410

Authentication type: <not set>

APN type: internet

Make sure you have these settings, then reboot. After the reboot, go into your APN settings and verify that the new APN is selected and not the default/old APN. If yes, do another speed test and verify that you have a 198 address. If yes, enjoy!! :D

[AT&T Samsung Galaxy S II SGH-I777] Jade Eyed Wolf:
Sounds to me like you're on the right network, but Salem VA is pretty far out in the sticks! Your network speeds (or in this case, lack thereof) probably come as a result of geographical location.

Even though there may not likely be as many people connecting to your towers as you might see in more densely populated areas, the towers you are connecting to probably don't have as wide a backhaul as what you'd see in more urban areas.

Your towers in Salem may only have single T1 trunks (1.5mbit up/down minus what other users are utilizing at any given moment), so that's likely where your bottleneck is.

The only thing I could suggest is to compare your speeds to what you get when you're ever in a more urban area.
[AT&T Samsung Galaxy S II SGH-I777] 02ranger:
I'll be driving through Winston Salem this weekend on my way home. I'll pull over somewhere and try my speeds there. Thanks for the answer. I've never considered Salem as being in the sticks but I guess maybe it is with regards to cell phone towers. lol. Thanks again. :)

On a sidenote, I used xtremelabs speed test app instead of speedtest.net last night and got roughly 1.3Mb down and 1.1 Mb up at 9pm or so. Maybe part of it was the app. Also switched from cm7 to touch-x ROM last night. It had several new APNs and that seemed to help in actual browsing. I'll post the new apns shortly.
[AT&T Samsung Galaxy S II SGH-I777] Jade Eyed Wolf:
Yeah, those speeds highly suggest a single T1 backhaul at the tower to me.

For me, it seems like one of the biggest/noticeable differences between the new and old APN's from a browsing perspective is response time. Even if speed tests are more or less the same, the new APN feels quicker because the latency is a lot lower (70 to 90ms pings vs 120+ms pings).

Also it feels like AT&T has a thing against Youtube; it feels like they never allow a video to buffer more than a few seconds before coming to a crawl all of a sudden on the old APN... :P
[AT&T Samsung Galaxy S II SGH-I777] 02ranger:
