I spent an hour on the phone with AT&T and couldn't resolve the issue of why I don't have data working.
Can anyone help me to figure out why I can't get data with this ROM?

Being this phone has T-Mobile radio bands the first you need to do is unlock it, which if you have the ability to make phone calls I assume you did this or someone did for you
Also you will need proper APN set up, this should have been something you tried spending an hour on the phone with ATT. So that leads me to believe that there is an alternative APN setup that you need, just do a Google search and you will probably find a couple setups out there and try them all
Do note that you probably will get lower data speeds being this phone isn't working with the bands that ATT uses - but I'm a T-Mobile user so haven't specifically tried to get mine to work thus have no experience to help further

I forgot to mention that data was working fine with the stock ROM, both the one the phone came with and the OTA upgrade version.
I just installed CM 11 snapshot M8, and have the same issue of no data. Prior to installing (through TWRP 2.7.1.0), I did a factory reset, then wiped Dalvik Cache, System, Cache, and Data.
Why would would the stock ROM work but not these others?
Did you go into settings and change the APN in cm11 yet?

That did it! I had to select ATT Phone. For whatever reason, ATT LTE doesn't seem compatible. I live in the hills, so have inconsistent coverage, but the indicator goes from 3G, to H, to H+, then back again, based on... wind, clouds, barometric pressure, or whatever the usual issues are. Anyway, I've been with AT&T since 05 and the only time I actually saw a noticeable increase in real-world speed was going from an EDGE device to a 3G device. 4G doesn't seem to be any faster, which I believe is due to backhaul issues, not connection speed of my phone to a tower.
Related
As with many skyrocket users, there seems to be trouble connecting to the AT&T data network for an extended time. the 4g icon indicates its connected but won't send or receive data unless packet data is disconnected and re enabled. After some hours of research and calls to customer service, I've found what could be a potential fix.
By dialing the ussd code ( *#*#4636#*#*) a menu comes up and gives you the options of
phone information
battery information
Usage statistics
And wifi information.
Under the phone information menu, an option for data network preferences appears at the bottom of the screen. By changing third setting, the connection issues should be solved...
however...
I can't seem to get any of the selections to stay. meaning, are I select my preference and exit, when I return to the screen its at its original setting. I believe it may change and stay if I rout which I haven't due to my phone being an AT&T company phone so if any rooted skyrockets would like to volunteer and test out my theory, we would all be greatly appreciated.

You are basically disabling the LTE radio (network) but it is temporary (for testing purposes). I think using a non-LTE APN will do the same thing and you can change it back when you are ready. Someone that knows more can correct me if I am wrong.
I used that method originally however I ran into the same issues. I was using the CINGULAR.WAP apn.
If anyone knows of another apn that I can test I would appreciate it

OK so this is what worked for me
For apn name i put AT&T and for apn type I put just : Phone and left everything else blank and even input the mms setting found online for at&t and that's got me hspa data so far

yes you have to add the other APNs for this to work. If you only have the PTA APN, it will only lock onto LTE if in a LTE area.
Now if you are rooted and running a ROM where you can change the network within the normal options area, you have to set the APN first then change to H+. It may fail the first time but try it again and eventually it will downshift to H+.

Is it because i have only 3g available in india..?? also will I be able to change to "GSM/WCDMA/LTE AUTO" when i come back to United States???
AT&T Samsung Galaxy SII SGT-I727 data issues fixed ...
I broke my old HTC Inspire. I purchased a Samsung Galaxy SII SGH-I727 off of the eBay as a replacement.
When I moved the SIM card over everything was fine, except I had no data, even though I have a valid data plan. I still had wireless at home, but my data plan did not work when out on the street.
I called AT&T, told them the issue, and that I suspected that it had something to do with "LTE". They made some internal changes, which sounded like they activated LTE service for me. Data plan now working perfectly.

I have requested my unlock code from T-Mobile. I have my Straight Talk SIM card ready to go. Now, my question is:
Does having Root and/or custom roms affect the process of unlocking a device?
I just want to make sure ahead of time so I can make the process as smooth as possible. Thanks in advance!
I believe you just need to be on a stock ROM, then it'll always be "activated" no matter what you flash.
So root makes no difference?
Doesn't make a difference.

You must unlock in stock, but once you do, you are free to root away.

Well I ended up having to flash a stock rom to get it to work, but my phone is unlocked. which led me to a weird question:
I put my friends Straight Talk sim card in my phone to be sure it was working, and the phone had service and data on it right away. I was able to make phone calls, surf the web, send texts (I didn't test out the MMS). I thought adjust the APN settings was a must for all that stuff to work...? I didn't change a thing. But then it got me curious as to what my APN settings actually were. But when I went to click on the APN button under settings>mobile networks, I get the horrible "Unfortunately the process com.android.phone has stopped" error. I haven't seen that since I stopped using Wifi calling. Now it looks like I can't change my APN if the need arises. Anyone know of a loop hole to this?
Does 3g/hspa work for you sorry to change subject but can't find info on this subject I'm thinking of moving to this phone from the thrill 4G but in afraid my straight talk Sim won't connect 3g since it's TMobile phone and straight talk is Att towers to best of my knowledge
Sent from my LG-P920 using XDA
Straight talk runs on a variety of frequencies from its parent companies depending on what device you have. AT&T devices are equipped for Straight Talk's 3G network because they operate on the frequencies. T-Mobile devices operate slightly differently. However, adjusting the APN settings correctly to transmit date via AT&T's service is supposed to to more or less resolve the issue. Unfortunately I can't seem to do that. It may be something to do with the rom I'm using, but I'm not sure. I'll have to text it out.
that would be awesome I'll keep checking back to see your results
Sent from my LG-P920 using XDA
If straight Talk uses Att's 3g frequencies then you won have 3g on this phone. This phone does not have the proper radio frequency for it.
Edit: look at my answer in your other post.

I have been having this problem with both of my Nexus S 4G ever since I got them 2 months ago.
My data drops out frequently and takes a while to get back up. If I have 4G enabled, then I have to manually reconnect it as it will not do it on it's own. This happens inside AND outside. Driving down the road or just standing in one spot.
I've tried all of the radios (basebands) and about 7 different ROMs and versions.
I've refreshed the data profile, PRL, and even tried the roaming Verizon PRL and Hybrid PRL.
Gone back to stock and tried everything from scratch. Still the same problem.
Dallas/Fort Worth Area
Network: Sprint
Baseband: D720SPRKE1
PRL Version: P:40447
I contacted Sprint and they just told me to update the profile & PRL.....
Any suggestions?
I'm not familiar with the CDMA nexus s, but are you able to change APN's? At one point I'd be able to connect to 3g (I have an I9020A), but every minute or so it would drop, so I fixed up the APN's for my carrier.
iv had a few data issues
forcing PRL and account updates has fixed it a couple of times
i'v bought used phones that iv had
to have sprint force update
im on LC1
[altho i cant tell any significant difference here]
and my prl is 61086
[a business account]
im currently on slim
make sure your mobile network
is set to roam
is not set to home only
Am I the only one with this problem? As I'm typing this I lost data but still had 3 bars. I never drop calls but only data.
Help please. This is driving me nuts.

i go thru periods of it acting bizarre
try disabling wifi and reboot
this USUALLY fixes mine till wifi is re-enabled
and i drop the sprint connection a few times
riding around
it then fails to re-acquire the IP address.
look in your status and see if you still have an IP
when your data fails
fwiw
I never use Wi-Fi. Ever.
Happens while using both 3G and 4G.

4G is worthless here...
i dont even bother with the switch
does it do the same thing if you disable 4G?
I almost always have to use 4G (if possible) since 3G speeds are slower than dial-up.
I've tried rebooting and leaving 4G off, and still the same. Even tried going back to Gingerbread.

In the original post, I stated that was one of the things I've done.
have you checked to see if you have an IP address

mine shows "unavailable" when it's wonky
and wont re-aquire till i reboot.

I have the same problems. From what I understand, its a problem with the hardware. I can confirm that's probably the case, because I've tried many different ROMs (stock, cm, etc...) and they all have the same radio issues (3g/4g and wifi)...
I have an NS4G in the DFW area and haven't seen the issues you're reporting. I'm currently on 4.0.4 with D720SPRLC1 baseband. Maybe I'm just lucky and have a good signal at work and home. It's very rare that I find an area of DFW where I don't get any data signal at all. Not sure what to suggest.
I get random drops too and i hate it. My 3g speeds are fairly good even above 1 mbps. Highest i ever got on 3g was 1.51 mbps
Mine will lose data if I'm in a coverage free area for an extended period of time, when I'm back in range 3g icon will show up just never reconnect. A reboot fixes it
Certain Areas
There are certain areas where I live that data just disappears. Although this is just a network thing I believe. It's weird though when I am driving it's like a 10 second drop and then all is good. Hope you get a solid fix!:victory:
Backup 4g Partition
REMOVED - was a bad idea.
I've actually replaced BOTH of the phones with brand new NS4Gs and they shipped with ICS.
Still the same problem.
This is driving me nuts. I was driving and trying to download Maps for the new phone from the Play Store and it took 6 tries. Kept saying RETRY.
What I've come to believe is happening is:
When 4G connects, 3G disconnects. When 4G drops (which is does frequently), 3G has to reconnect.
***Is there a way to keep 3G "on" in the background while 4G is connected?*** Maybe a way for the radio to transition back and forth?
So I've been having the same battery problems as everyone else. I'd like to disable LTE on my ATT 727. Knowing that I could force protocols on prior phones, I went looking for the options to find none. So I decided to flash CM10. I learned after flashing CM10 on my device that the radio needs to be flashed also. I've tried flashing a few different radios but it appears that they simply aren't flashing. Recovery goes through the motions but the version never changes. I've read rumors that I need to do a subsidy unlock but I haven't seen any real confirmation of it. Is that true? A carrier subsidy unlock must be done to flash over the RAT locked ATT radio? I would expect that to be in the noob listts with radios if so.
Baseband version: I727RUXLF3
Kernel: 3.0.49-cyanogenmod-g5756af3
Recovery: CWMR Touch v5.5.0.4 _sk8_
Thanks in advance for the advice. I really want to like this device. Hopefully between wakelock and LTE we can get it useable.

There is a dialer code you can use to access radio settings and turn off lte. I don't remember what it is offhand.
This: *#*#4636#*#*
^^Type into dialer^^
Also, try updating to a newer version of sk8's cwm.

Thanks for the info. I wasn't able to find the text you referenced to read it in detail. It looks like you're telling me that CM10 has a bug where the network mode can't be set for AT&T Skyrockets.
Do other roms have the same problem?

This is the same for pretty much all recent at&t smartphones. Last 5 I have had have had that option blocked. There is a possibility if you pull the sim card out, boot phone back on, use the dial code listed previously to set it and then put sim back in you might get the desired results. Not sure they will stick though.

Perhaps I've misunderstood but I thought I had read that flashing the Roger's radio would fix the problem as it's RAT unlocked (whatever that means).
I can pop the sim out and see what happens.

you could also go to your APN's and switch to the non LTE one
this will stop you from having mobile data altogether in some areas but will give you the desired battery effect

Don't know about Rogers that is why I said at&t. I haven't even been able to get the rat selection screen to give any other option but lte ones on this device. On my lg thrill I was able to get different options by popping the sim out like I suggested but of course that is a non lte phone.
As a side note, I haven't seen much difference in battery life between running lte data or wifi data. I could see this as beneficial if in a non lte area or weak signal area.

Maybe replace it?
If this is a new phone that you haven't tampered with, I suggest that you exchange it. New phones don't need any change in settings to connect to LTE out of the box.
Maybe it's a hardware problem. Did this problem just appear out of nowhere? (maybe after the update)?
