Possible fix to data connection issues - AT&T Samsung Galaxy S II Skyrocket SGH-I727

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+.

i m have unlocked skyrocket, currently in india using a 3g/4g sim card. i went through the *#*#INFO#*#* menu and selected "WCDMA Preferred" then i turned radio OFF and ON back again. since then it is set to "WCDMA Preferred" only and i m unable to change it.. 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.

Data Problem, What Should I Do?

I just started having this issue, i can't connect to any data at all, i have tried battery pulls, using restart connection, running different roms, using restores where everything was working, doing a full wipe and then installing a new rom, but still no luck. Should i try just a factory restore? i also read that taking out the battery, then take out the sim card, booting the phone up with out the sim card in, getting errors and then shut it off and then put the sim card back in works, but im not sure which of those to try, any advice?
when that happened to me i did a factory reset and it worked afterward
Check around first, see if Verizon is having problems in your area. I know recently places have been popping up with sporadic outages.

But isn't installing a rom and wiping the data and cache the same as a factory restore?
I had this happen to me earlier this week. When I called Verizon support they told me that towers were down in my area, they told me the same when I called back the next day. Meanwhile, others who own the TB seemed to be having no issues. Finally I took my phone into a Verizon store and they are shipping me a replacement phone. They would not swap my phone in the store since I was a whopping 4 days beyond the 14 day return window...but, I digress.
The one workaround that I found in the meantime is to switch your modem settings. Dial ##778, select Edit Mode, enter 000000 as the password and select Modem Settings. Select Rev. A and choose Enable. Press your menu button and select Commit Changes. Your phone will reboot and you can use the LTE On/Off App (or just dial *#*#4636#*#* and choose Phone information) and switch the radio to CDMA Auto (PRL). That enabled me to have 3G data, though it seems extremely slow relative to 3G on my OG Droid. But, in a pinch it seems to work.
One additional bit of advice, in case you are running a custom ROM. I was running Virus ROM and ##778 would crash whenever I tried to run it. In order to swap the modem settings, I had to flash back to stock and make the updates, then flash back to Virus. I don't know if this is specific to Virus, but just an FYI.
Just tried on das bamf and worked fine (##778) must just be virus.

You won't get 4G on that setting, it turns the 4G radio off entirely. You would need to switch back to the CDMA + LTE/EvDo auto or LTE mode settings to get 4G. Ultimately, my issue ended up being a defective phone. You can try to wait it out and see if you get 4G back later, but you may just have a faulty device.
If that is the case, just remember to follow the instructions that jcase posted in the development forum to get your phone back to stock with s-on before taking it into a Verizon store. If you bring a rooted device in, I suspect they aren't going to honor any sort of warranty.
My phone had this problem too... turns out when I went into a 4g area the mobile network box got unchecked in the wireless & network settings.
I use the "verify with multiple devices method". I am tired of the standard VZW "towers are down in your area" bs answer.
If another tb, xoom, and bb have service and my tb doesn't, that tells me something is wrong.
I have a feeling that there is something seriously wrong with the network (implementation or backend hardware) that is causing this with 4G devices. Either that or the tb is to blame entirely for Verizon's 4G issues...... /rantoff..... LOL

Was having issues earlier today with 4G. The connection and signal were good, but no data would download. The white up arrow would light up, but the down arrow never would. It was like that for about 4 hours. It's working great now and speeds are disgustingly fast.. maybe VZ doing some maintenance?
EDIT: THis is in San Diego.

Factory Reset from bootloader worked for me. I had the exact same problem. Tried everything that was suggested, but no data still. Only enabling Rev. A worked.
Thanks for the help, the problem I'm having now is I got 3g but I can't get 4G back, I have tried to switch my settings back to get 4G using LTE on/off and by dialing the number, and I have had no luck, in those menus it tells me service type LTE but it is disconnected, and I get no data or 4G symbol in the status bar, so I'm confused if I maybe messed up a setting or what, so should I just try a factory restore via the bootloader and see if that works? Any other suggestions ?

I would try the factory reset from bootloader, but I was on the stock ROM when I did it. So I don't know if that would matter or not.

Just to reiterate, my 4G never came back. The phone was just broken. It sounds suspiciously like you are having the same issue. Maybe there is a manufacturing defect that makes this issue more prevalent with this phone right now? If you are in the 14 day return period, set your modem and radio settings back and get into the store ASAP to swap the phone out. Otherwise, call customer service and have them replace the phone. They will overnight you a new phone if you complain enough.
Ok I was looking through my modem settings after dialing ##778 and I had changed the rev a. Setting to enable, that got my 3g working, but what is eHRPD is that would I should have it on too have 3g/4g? But everytime I have tried setting it to that I get no data so is that the setting that is messed up?

Cellular Data stops working after airplane mode or in\out of coverage return

Replicated this on 2 different Infuse 4G using 2 different SIM cards.
I notice that about 50% of the time when I come out of airplane mode, the data connectivity on the phone is gone. The only way I've been able to figure out how to restore it is to go into APN, open the apn settings page, then press save, and that seems to restore it.. yeah, annoying a little? hehe
The other time I notice it, while less frequently, is when I am out of coverage, ie an elevator or sub-teranian environment (hehe, I like that word better than basement), and then I return to coverage. turning airplane mode on then off doesn't restore it like many issues, nor does a complete reboot of the phone, so it's really strange. the only way I've been able to solve it is to go in and tap the apn settings then resave them, which obviously isn't the ideal way to resolve it.
Anyone else having this issue? I have replicated it on the 2 Samsung Infuse 4G devices I have, and they were both setup independently.
I flew the day after I got my Infuse and four days after I returned home on the next flight...No problems with airplane mode. Just playing around with it now, I'm still not encountering any issues.
I do have occasional issues that require me to enable/disable Wi-Fi...it'll only hop wi-fi spots once or twice, then I have to enable/disable wifi to get it to hop on a new one. Won't scan properly.

Are you AT&T? I'm wondering if it's something AT&T is doing to the phone then. I'm using an MVNO of ATT's sim card, so the apn that was on the phone originally was deleted and I replaced it with the new APN info.
Yes, I'm on AT&T directly (using an ancient Cingular 3G SIM)... obviously, I didn't have to change any of the APN info as a result.

I just tried my Tru Mobile (It's a global roaming voice\data sim). I changed the APN and it's doing the same thing. Bugger.
Would AT&T really script the phone to try and hassle someone for using another sim in the phone? Weird. Hopefully when a flashable ROM comes out it'll solve this issue as I never had it when using CM7 on my Inspire 4G, nor Aria, nor Captivate.

HAHA, that's funny. I always forget it's AT&T we're talking about.
I know this is an old thread, bu this happens to me too. I'm running Infused 1.6 and the same thing happens to me. Into and out of airplane mode I can receive but not send text messages. Or if I travel through an area where there is no connectivity then I receive but can't send text messages.
My fix is to restore the backup data for "[SMS/MMS Prefs Messaging 2.2.1]" using Titanium Backup.
Seems more like an issue with your sim cards than the phone.

[Q] No Edge, 3g or 4g

Last week I stopped being able to use the internet, marketplace and streaming service on my Galaxy S 4g unless I'm on wi-fi. Today I realized it appears as if I'm no longer getting edge, 3g or 4g service. I have bars, but nothing next to it telling me what network I'm on.
My phone is rooted to stock with bloat removed and has been for months. Any ideas on how to fix this?
Try toggling airplane mode. Might help to remove your SIM card & ensure the contacts are clean then reseat it.

try taking the battery out for 10min
I guess I figured it out. But it doesn't seem very logical, but hey it works.
I changed the url of my provider from "live.vodafone.com" to "live .vodafone.com" (watch the space between live and .vodafone) and all of a sudden E/G/H appeared in the status bar.
Still, double check the APN settings, make sure everything is entered in right (proxy, username, authentication type, etc). Were you able to send pictures still? You need to make sure it's not a hardware problem.

Airplane mode is a feature of the phone and turns off all radios. You can hold the power button and choose airplane mode or use the quick toggle in the notification window. Since it sounds like you may be in an area with weak 4G, you can also use an app called Phone Info to set it to CDMA auto (PRL) under Device Information. You can also change it back to LTE/CDMA/EvDO if you want it to switch as normal.
With the Verizon S3, is there the need to do *228 (or *22899) ? I did this every so often on my old HTC Incredible.

Doesn't work on LTE devices. A reboot essentially does the same thing. Some have recommended pulling the battery with the phone on, removing the sim card for about 30sec and then putting everything back in.
Thanks, I know what airplane mode is, wasn't sure where the APN setting was. I will look in to phone info though.

Are you guys also experiencing the "No Sim Card" and "No Network Connection" issues?
Or is this an entirely different issue?
When this phone goes to 3g, it does seem extra bad on how long it takes to switch back to 4g. i have areas where i live where it goes to 3g when going in between hill (less than a 50 foot stretch) and it will not go back to 4g for over 10 minutes if i dont manually do it. Not to mention my LTE never goes above 10 mbps on the best days
Somewhat related...If you use Anycut to create a shortcut to IOTHiddenMenu, enter the ##DATA# Menu, edit. Under "Advanced", there is an LTE toggle, under "Other" > "HDR/1X" you can set the phone mode, and then under "Other" > "LTE APN Settings" you can somewhat modify the APN settings, reset and discard. If it asks for a password, it's 000000.
I gave these a try. I'm trying to find a way for my phone to favor 4G when there's a 4G signal, no matter how weak.
Yesterday I did a test, 3G with 3 bars vs 4G with 0 to 1 and 4G had consistently faster download speeds and shorter ping times. The upload varied from similar to 3G to slower.

probably easier said than done. The phone info app can force LTE but you lose voice and text.
Ya I found that out yesterday when testing speeds. I went to send a text then make a call and no luck
Otherwise 4G service where I live could be excellent at one spot then a mile away no service. If I had excellent 4G consistently I'd consider GoSMS which I believe has the option for data text and also a separate VoIP app
Ah well hopefully something will be figured out eventually. With a strong 4G signal 4G is considerably faster and more consistent than my 20mbps home broadband

I've had similar issues with my network. I had no 4G in 4G areas, but mainly my wifi would disconnect randomly and 3G also dropped to 1X a lot. I ended up having to send it back and get another one. So far no issues. Also the new ones have an "Updated" sticker on them. I think it was just a software update they applied, but I never got the OTA on my old phone.

Not sure if anyone will have the same luck I have with the "Phone Info" app, but with it I was able to get my 4g service back and my phone is functioning normally again. Just open the app, select Device Information and scroll down to "Set preferred network type" and select "LTE/CDMA/EvDo" then get out of the app.. 4g should return shortly there after. When I looked at it, my device was set to "GSM/CDMA auto (PRL)"

[Q] XT1045 won't connect to LTE

I picked up an XT1045 (Moto G LTE USA) recently from Amazon and had T-Mobile ship me a new micro-SIM, then called them to activate it. I know there are LTE towers around (had customer support tell me as much) but I never see "LTE" in the status bar, always "H" or "H+". Granted, download speeds in San Jose on HSPA+ are pretty fast, but I am wondering if I'm missing something fairly obvious. I have the default LTE APN selected.
I did unlock the phone using the Motorola site and rooted it. Could this interfere with LTE operation somehow ?

Which APN are you using. You should be on fast.tmobile.com
I have the similar setup (xt1045,unlocked bootloader, rooter, stock 4.4.3 and stock kernel) and don't have any issues. It did take a few hours after first boot. I am in a refarmed area however. Mine defaulted to the lte/fast apn.
a few things:
- tmobo indoors isn't great in all places, so try outside
- if you're on wifi, they downgrade to hspa/3g to save battery, you may not see lte until you get off wifi
- you may be over your monthly 4g cap
to be honest, their hspa+ speeds are same as lte out here anyways

Even if you are over your monthly cap, you still connect to LTE. It just lowers your speeds.
Thanks all for the info. I'm using the T-Mobile APN that came with the phone (fast.t-mobile.com), wifi off, have tried indoors/outdoors.
I'm pretty sure I'm not over my data cap -- my previous phone was a Nexus S and my data usage habits haven't really changed yet
It is a much snappier phone and the HSPA+ and wifi and GPS really are much nicer. I like having the microSD slot too. So I can't really complain too much.

Scroll down and force it to LTE Only
Turn on/off Aeroplane mode if needed.

Never saw 'Phone information' come up. I'm assuming this would be the same as changing 'bearer' in the APN setting to 'LTE' instead of unspecified (tried that already, it just seems to get no data at all then) ?
Have not had airplane mode on for these tests.

So when you dial *#*#4636*#*# , what is the first menu on the top?
It's not the same, cos if you set it there, it allows of 3G connections if no LTE available (dunno if you force it from Settings -> More.. -> Mobile Networks -> Network Mode -> LTE ).
The Airoplane mode is just to "relog" to the carrier network , you just cycle through it On->Off

The last four characters were #*#* in your first reply, and that didn't seem to have any effect at all. When I tried the sequence above and pressed dial, it first said 'USSD code running' and then 'Connection problem or invalid MMI code'.

The correct combination is *#*#4636#*#* and you dont have to press dial after that, the menu should pop-up right after you press the last character.This is not model specific either, it works on all android versions/roms.

Apparently doesn't work on this phone. It's ok, google led me to a couple of apps which appear to do something similar. Thanks for the insight !
Finally got the "LTE" indicator while outside eating lunch near work today. I was amazed that the speedtest.net app reported ~30Mbps down / 20 up. Didn't have to mess with the default T-mobile LTE APN. I guess T-mobile's coverage is just kind of spotty, but maybe the nearby tower was just upgraded or something like that
