OK, I have been dealing with this since I bought my GSII and cannot find any information about it.
Firstly I want to say that I am completely stock and unrooted.
My phone does not like to keep a stable data connection. About 50% of the time, when I try to do anything that requires a data connection (facebook, browser, gmail, etc.) the 2 arrows under the 2g/3g/4g icon will stick being grey and my phone just sits there "loading". I tried a factory reset, didn't install any apps, and also got a new sim card and the issue remains. It happens everywhere so it is not just a bad network connection.
I decided to post the question here because yesterday I was playing with my brother's GSII, and his did the same thing.. So it made me think that maybe it wasn't just me. Has anyone else experienced this? Or does anyone know what might be the cause?
Edit: I set my phone to use 2g only, and the problem vanished.. So it doesn't like to connect to 3g/4g.

Try going to your mobile network connection settings, choose access point names, hit your menu button and click "restore defaults".. It may fix it, I had data issues and it did the job. Hope it works for you!

Do what the gut above me said. Also call Tmobile and tell them, they will refresh your data connection on their end. That will clear up three problems your having.
But if it's also happening to your brothers phone, it's a network error. Call Tmobile.

I restored the apn settings and had Tmobile refresh my data connection, and it still happens. I noticed today that it's not just data, I'm also unable to call or text when it happens.. Tmobile just said everything tested normal so there is nothing they can do.. And I really don't think it's the phone so I don't want to exchange for a refurbished unless I have to.

Its happened to me before. For about a week, the data connection just dropped. It would come back for a bit and later vanish. I called t-mobile and they guided me through routine steps (i.e. taking the battery out, rebooting, resetting) but nothing seemed to work. They really couldn't figure it out and later told me to replace the SIM. I can't remember if they shipped me one or had to go to the store but either way that relieved the problem. This was on an HTC HD2.
That might not be the case with you though. At one point in time all the phones under my name lost data connectivity just as you explain. This really had no solution but to wait it out.

you mentioned your brother's is doing the same thing, its probably not the phone, but rather the cell tower your connected to is fuggin up. Try going 5 miles from where you currently are and see if its still happening.
Network error
Sent from my SGH-T989 using XDA App
Just in case it's not a cell tower or network problem . . . My SGS2, purchased in October, had the same symptoms as the OP. After trying everything the OP did, and more, I came to the conclusion that the firmware on the phone was corrupt. I used Odin to flash the factory stock ROM & Kernel images (2.3.5 at the time). There was a definite improvement in the faltering/hesitant/fail connectivity problem at that point, but it was still very subpar. So I then also flashed, again using Odin, the baseband ("modem") image - I did it twice for good measure. The problem was finally immediately solved at that point and I had very prompt loading of webpages, etc. Still working fine months later (and even better with a custom ROM). See the thread entitled "[Q]Is there a "true" factory restore for T-Mobile Galaxy S II?" for help about the seemingly same symptoms/problem you (and your brother) are experiencing. If your underlying problem is in fact the same as mine (and the poster of the thread I cited) then it's apparently either a bad factory flash or a post-factory corruption occurrence that is causing your problem . . . the coincidence of your brother also having the same problem aside. Good luck!

Hey, for some reason my mobile data/gps decided to stop working this morning.
I used my data on my way home from work last night, set the phone to charge and when I left I noticed I had no data connection.
I check throughout the day and nothing but I continued to get text messages and calls.
Sending MMS message also seemed to have stopped working.
Is it something thats messed up with my phone? I tried changing settings in the ROM, going back to stock, nothing seemed to have worked. Any ideas on how I can fix this?

Checked it properly. Checked the ones from my providers website. Tried different ROMs. It doesn't seem to work.

Call your provider and confirm that you still have a data package on your plan. Im not sure how long you had your phone or if you got a new phone but whenever i switch between phones and ATT scans for the new IMEI number and it doesnt match what they have, they always kick my data off and then i have to call them to have it added back.
Hey guys, I'm using the Galaxy S3 and my current carrier is Rogers. I've always been on 4G in the area that I'm in, and with the countless roms I've installed I've never come across any problems. Today I was trying out some new roms, but when I flashed them, I noticed that it swapped from 4G to E(aka Edge). Even if I flash back to my nandroid backup or even a fresh install if the previous rom I was using, I'm still stuck on Edge. Now even though it says I'm connected to Edge, never mind reduced speed, my internet just doesn't even work at all. For some reason even if I'm connected to wi-fi, no matter what I do it says there's no connection. I've read about flashing modems, which I have tried and it seems I'm doing it wrong? I put it on to my sd, boot in to recovery and flash it, but whenever I do I just go in to an endless boot loop. I've spent the past six hours pulling out my hair and trying to get this fixed but no solution yet, so now I've put my hope in to you guys! Any help would be appreciated!
Thanks!
P.S. I'm sorry if I can't reply back right away, I'm currently doing night shifts at work and even though it's 9:45am here, it's technically my bed time, so I will get back to you as soon as I can!
Some extra information if it may help - The rom I was using that worked properly was Triune 2, I've played around with a few roms since, but the one that originally swapped my 4g to Edge was Mark of the Dragon 3.0.
I can think of two possibilities:
1) Some ROMs will reset your phone's internal network settings to only use specific types of networks (e.g. when I first got my phone, the CM10 build I flashed at the time disabled LTE). You can check this by dialing *#*#4636#*#*, going into "Phone information", and scrolling down to "Set preferred network type"; you'll want one of the LTE settings.
2) Reportedly, your phone's IMEI will sometimes be erased during a ROM update (check this in the Settings -> About phone -> Status menu, or in the same "Phone information" menu as above). Check here if that happened.
Hey, I gave number 1 a shot and everything was fine, so I took a look at option 2 and my IMEI isn't gone, but it's showing "0". I searched online and it seems like "0" means it's been deleted, so I'm about to give it a go and see if I can get it up and running. Anyways, thanks for the reply! I'll post and update on how everything works out.
*UPDATE* Alright, problem fixed! I'm back at 4G, everything is running smooth and fast! Took a little bit but everything is working fine, and now I know how to fix this problem if it should arise again, thanks again for the help, I appreciate it!
Hey, I'm back again. Well, I thought the problem was fixed, I was back on 4G all day until a little after I started work at around 10:30pm when my network swapped back to Edge and it's been there since(now 6:57am). My IMEI is still intact as well. I've tried flashing back to stock with odin and injecting the file to see what happens but no luck. Unfortunately I haven't reached the 10 post marker which means I can't ask for help on that part of the forum yet, so here I am in your hands once again, any help from you guys would be greatly appreciated!

Out of curiosity, have you checked the "set preferred network type" setting again?
I've also heard recently that there may be some problems with Rogers APNs in non-standard ROMs, so it might be worth checking your APN settings.
Or, it could be an LTE network outage, unlikely as that seems...
Yes I have and everything is fine. However, I was looking around at a few things some other people have done, not with the exact problem I have, but similar, I tried something out and it worked. Dial *#197328640#>UMTS>DEBUG SCREEN>PHONE CONTROL>NETWORK CONTROL>BAND SELECTION>LTE BAND PREFERENCE>LTE ALL, let it sit there for about 30 seconds and then reset the phone. Do it again, go in to BAND SELECTION and then choose AUTOMATIC, wait 30 seconds and reboot your phone again. I'm back to 4g and actually, it seems faster than when I originally had 4G, but I think I'm just used to how slow Edge is now . Although the other fix got me back to 4G as well, but then it swapped back to Edge so I'll wait for at least 24 hours before I can confirm it completely fixed. Once again thanks for the response! Most helpful forums I've been on!
It hasn't been 24 hours but I thought I'd report back while I'm on my break. I'm still at 4G so things seems to be going well, hopefully it won't go back as it seems like it will stay at 4G. So, unless I'm having troubles again, rather than waiting the 24 hours and posting an update, think of it as a good thing that I don't report anything(or at least I will, since it's my phone ) Thanks again for the help, I appreciate it!

Thanks do much for this, I had the exact same problem after flashing MiuiAndroid and Wicked Sensations. Don't know which one effed it up but it was definitely one of those two. Also, I Don't think it is a placebo effect on the speed increase, cause mine is blazing fast after implementing this fix. You should maybe re-title the thread so others in this situation can find this fix, good find and thanks again!
Just want to confirm that this particular code can only be entered from a stock dialer? I I tried entering it from cm10's dialer and it doesn't do anything.

2 things that i can think of...
1)Make sure you have the LTE option selected in your Mobile Networks.
2)Take a look at your APN settings for you carrier. Flashing roms sometimes erases these settings.
That's where i would look first...
Cheers

Please let me know if you fix this. I'm having the same problem, and playing with LTE band selection doesn't work. When I force the band selection, the phone won't even go into service. The same thing happens with WCDMA.
Apparently, the nvbackup stores more than the IMEI. Even when you replace the IMEI, nobody seems to get data back. Unless, of course, you had a backup. Which, unfortunately, I was not smart enough to do....
Hey guys, I have the exact same issue as this:
-I flashed CM10.2 from a CM10.1 nightly which wiped my IMEI. I injected the IMEI using NV-items reader/writer.
-Reloaded stock ICS rom, IMEI returned but couldn't get up from EDGE
-Tried using the peoplesarmy's removed IMEI restore tool, didn't do anything
The phone still works, only its on EDGE all the time.
Literally the only solution for me was using my warranty and getting a new phone.
REPEAT: BACKUP YOUR **** OR YOU GOTTA GET A NEW PHONE!
Note II randomly has emergency call only ... i have signal bars but cant use phone text data anything
- i reset to stock rom via odin (only flashed a pda) - didn't fix
-tried another sim in it - same result
- my sim works
- phone is not stolen
- factory reset
- checked APN
- Airplane mode, reboot etc. all done
anybody have any ideas how i got to this? just switched from an iphone kinda dissapointed right now .thanks for help!
What did you do prior to having this problem?? Did you flash a Rom? And it started a lil while after that? Kinda need lil more info.
Is the phone used? Could b many things.
I'll say this if you just got the phone, and it's from a retail store return it and get another one.

Did you check your modem ??
Did not see that on your list of repairs....and if it's wrong....no data.
Was your Odin rom complete with the baseband ????
I am having the exact same problem.
I literally didn't do anything for this to start happening. I use the I317 model of the Note 2 (obviously)
In the past couple of weeks, I am constantly losing reception for long periods of time and getting the same emergency calls only message.
I have bars as well, but don't see HSPA+ or LTE arrows... indicating data.... I don't receive texts / texts won't send.... etc. Can't use data reliant programs.
I'm beginning to get severely annoyed. Reception will eventually lock back on after about 2 hours.. .and I'll get all my alerts at once etc...
Very very annoying, why is this happening. I never did anything
This has happened to me twice.
The first time I had to restart the phone.
The second time I just tried again and it worked.
It was about two weeks between occurrences.
Never rooted.
Running stock UCAMA4.
No idea how to help you I just know what happened to me.
Network changes and downtime are not uncommon either as they upgrade and change often.
Not sure really, just thinking out loud. ...g

I'm having the same problem as the original user. Here's the background:
I bought an AT&T unlocked phone to use with my T-Mobile account. Worked fine.
Decided to root it & remove bloatware.
Immediately upon rooting, I noticed several problems, including no network access. Decided to restore to original condition.
Flashed the complete factory default, from SamMobile, using Odin. Upon completion did a factory reset.
Most of the bugs caused by original rooting seemed to be solved. But still cannot make calls.
Upon turning it on, I get the "no network access" symbol, then I get bars, but only a couple. Any calls yield "emergency calls only" message.
I unlocked the phone again to make sure that hadn't been undone, but no change.
If I go to settings, more settings, mobile networks, network operators, default settings, manual; then it finds AT&T and 3116600.
If I do the same to my spouse's phone (same phone, same network, just never rooted) it also finds T-Mobile.
How do I get my phone to find the T-Mobile network again?
Please keep in mind that I am very green at this. All I know is what I have learned from reading online material for the last two weeks, so please try to offer any instructions as clearly and simply as possible. Thank you very much!
If the phone says "no sim inserted", your sim tray might be defective (happened to me)
if it says no network access (emergency calls only) then theres some other problem
It doesn't say anything about the sim. And actually it doesn't say anything about the network. When I first turn it on, the "no" icon (zero slash) displays in the tray. Then it gets some bars, but if I dial a call, it displays "emergency calls only".
lol guys....

Emergency calls only
I have same situation. I downloaded firmware from switzerland, then at first it looks working,then I saw the problem which is,
phone cannot connect to operator.
instead when I search for mobile networks it can find it,but cant connect.Then I realised the firmware I used did simlock on my phone
After that I tried all firmwares which is related with my region Turkey. it did not work.
I went to phone tecnical shop to repair it. They fixed it,BUT I could not upgrade sammsung software,because its modified firmware. Even if I want to change firmware again I am having same connection problem. I asked the guy who fixed the phone,how did he repaired, he said only way that to fix it,we have to have sammsungbox, sambox,or I have to change motherboard he said.

If the phone is unlocked it should find T mobile just fine but, you will not have 3g unless you flash the aws mod to use tmobile 3g. My note is unlocked and when I put a tmobile sim in it takes a few minutes for it to connect to the tmobile network.
Once you unlock a phone rooting and flashing roms won't affect the sim unlock.

Just a thought but you can try shutting down phone, pulling out SIM card and gently use a pencil eraser to clean the gold contacts on it. Make sure that you blow/brush off any eraser particles. Put SIM back in and make sure it is in there correctly. Power on and hope for the best. Unless your service is shut down seems most "Emergency Calls Only" errors are from SIM card issues. May have to replace the SIM. No guarantees but worth a shot

(JediX20 and JediMaster + PacMan 4.2.2 and 4.3 + Stock Firmware Samsung 4.1.1 and 4.1.2 and even updated to 4.3 and downgraded back to 4.1.2) Nothing seems to work sometimes when I boot up ill have signal and my phone will work. Sometimes ill make a call while I have 3 signal bars or more and the phone will just be in dialing mode and after 10 seconds or so my signal will cut off and the call will disconnect saying there is no signal or "out of service area" and as soon as it hangs up my service bars reappear. And then there are times where the phone will show no signal strength at all for the whole time. In all instances data will still work. I have flashed and recovered through odin multiple times but I know the issue lies within the software I just dont know where. EFS maybe? I even thought it was in factory mode and downloaded titanium backup and deleted every "Factory Test Mode" I saw. Still no luck and im bout to the point im about to chunk it. Any ideas of why it is doing this? Any help would be much appreciated.

Possible on the EFS...but that file is really an all or nothing deal...
It is possible to have a bad antenna or radio chip....but I do agree with you on a software fix first...to include a custom APN setup with experimented entries...
I've also heard that arbitrarily bouncing between 4.1 and 4.3 roms does alter the partition structure slightly ...but after looking into the EFS on both frameworks....I've noticed they have the same size and the information is identical...
I wish that I had more help for you....g

My apns are fine and have always worked. The problem is not with that but rather signal strength, being able to make and receive calls. Messaging and data work fine.

My phone has always worked flawlessly until now. The signal can be normal but when I make a call it rings forever. .. the signal drops..my phone says it's out of service area and hangs up. .. and soon as it hangs up the signal bars reappear. .. in that specific order. It had never done that before until recently

If a radio/ril package doesn't repair the situation for you...and a complete return to stock fails also....(stock contains radio/ril )...
Then you should consider a hardware repair...
The note 2 had antenna issues on some devices...g

Greg,
Do you know where I can get details about the antenna issues. I searched several forums that pointed to the usb flex. I just replaced mine and still have the same problem of weak signal and constant signal drops.
Thxs
Thanks man ill try this out. Isnt there a way to just wipe the efs, system,data, dalvick, cache in TWRP and start fresh?
Do "NOT" wipe your EFS FOLDER...and do "NOT " re-partition your device in Odin either...
Simply use TWRP and wipe system ...data....dalvik...and cache...
Also ....you can wipe your internal storage as well if your important items are stored on the external SD....(photo's etc.)..
And as for the antenna question ...just Google it....g

I was poking around in my efs folder and went to Factory Apps and found a factory mode script. I opened it up in RB text editor and found that the script said on so I assume that it being on must have had something to do with the call feature. I changed the script from on to off and saved it. Soon after I tried making a bunch of calls its been working flawlessly but in exchange the lockscreen will not show up nor does the option to reboot/power off/airplaine mode shows up. Im going to Keep testing the calls in the meantime.

Im experiencing a problem nearly identical to yours. I have an i317 unlocked using a Tmobile SIM. Everything was working fine until I flashed a rom (I believe I accidentally flashed a rom with a Tmobile radio which boot looped the phone). After fixing the bootloop and flashing the cyanogen mod rom, I started experiencing the frequently dropped signal.
I have downgraded and gone back to stock several times which has not fixed the problem
After reading this thread I changed the factory mode script to off, but it doesn't seem to have affected the radio performance.
I remember reading that the partition could possibly be corrupted in a bad flash. What is the best way to reformat the partion?
Any help greatly appreciated
Did you reboot the phone afterwards?

Yea still no luck. But after about 3 days and a crapload of flashes I ended up flashing jedix20 and added the alexander theme..which suprised the hell out of me...the stock jedi had less signal bars like 1 or 2. I flashed alexander theme and my bars are from 2-4 with 4 being the best. Everything seems to be working. I had also did a test and made sure that my Network in setting was registered to the HOME network. That may have played a factor as to why the network wouldnt work even with signal bars. I flashed JediMasterX2 and ran across an issue like that. I flashed the att carrier files and it didnt work. Then I flashed the 7105 version and checked the Network operators and searched for a network. It pulled up AT&T and Verizon and when I chose AT&T and it registered my phone everything started working. I dont really like messing with the system files but I investigated the Jedimaster zip and looked under Jedi> carrier> att> and opened up the cscversion.txt under rb text editor and it showed an incorrect version. I317ATTAMA4....which im assuming was supposed to be I317ATTUCAMA4. Also under the SW Configuration. Xml the csc version was still the same. AMA4 it may be nothing but I would have thought it would have needed to match up. Ill have to look into it some more. I really want to update but hell idk. Might be done trying to flash roms on this device if everything works right

Would the phone having factory test and factory mode on the phone affect it any. I seem to have 2 factory mode apps with one being 560kb and the other 84kb. I don't know if those could affect the signal performance

Tbh. I honestly never got it to work right. I tried for months to get it to work right and to no avail. I ended up selling it and getting the note 3.
