I am admittedly a noob when it comes to Android phones. I have had my i777 for a few months now and have successfully bricked it more than once. Having said that, I have found that the answers to my questions have always been on the board somewhere. I am having troubles figuring out where to go with this portion of the issue though. Having tried several different ROMs for my phone, I keep having the same issue. With any ROM, other than stock, I miss phone calls or text messages when my phone is locked and on Wi-Fi at home. If I'm out and about with my phone in my pocket and locked, it works normally. But, if I'm at home working at my desk and the phone is locked, I will not get text messages or phone calls. Notifications from apps like CNN continue, but nothing from the mobile network. I have followed the guide to return to stock and built my own jig that worked to reset my flash counter as I flashed before I read when I got the phone. (Former iPhone user that just assumed it was as easy as a jailbreak, really really dumb on my part)
I am a tech geek. I follow instructions well. I am sure the problem is with my phone and not the ROMs. My question for the forum, is where to begin troubleshooting the issue. I want to be able to use these ROMs.
Some info that may be helpful:
Baseband: I777UCKH7
Kernel: 2.6.35.7
I have tried the following in no particular order:
UCKK6-SHOstockV1.9.2noWipe
Serendipity_8.2
update-unnamed-v2.2.1-full
ICScrewD_2.1
TurkbeyRom-v33
Each has individual issues that I can deal with and learn to fix, but the phone issue I, obviously, cannot get past.
Have you set the phone to keep the wifi active when sleeping or locked?

No I have not. Does the wifi connection prevent the cell network from connecting?
cell network shouldn't disconnect at all if it is, swap it out could be bad phone. Also what is your signal level at your desk at home? Low signal normally causes missing of messages.

No, it doesn't.
Do you use any 3rd party apps like tasker?
When did this issue start? Perhaps there is an issue with the tower that serves your home. How strong is your cellular signal at home? I believe text messages (except MMS) are sent over the cellular network. Your being on wifi shouldn't matter (does being at home with wifi off and the phone locked still cause issues?).
I can't imagine other ROMs causing issues, though. If anything, they would mess up your data network only if they had the wrong APN settings for your area (for example, for a while, people using Unnamed didn't have data issues, except for a few like me who lived in certain areas with Cingular towers). Or maybe the stock modem files are better for you than the ones provided by the ROMs?
Maybe you have an old sim card that somehow has issues? You should be able to get a free one from at&t. Do you have another phone that you can test it with?

I keep a minimum of 3 bars and live near the center of a large city. As stated in the op, this is only happening on added ROMs never on stock. I have again reverted to stock (+root), since the op, and confirm that I am getting messages and calls at my desk at home with the phone locked.
****************************Edit for SoCaliTrojan post********************************************
I do not have any additional task managers installed, I've just always used the one built in. As for the SIM card, I am using the one that I got with the i777 at upgrade and get the 4G network when not on wifi, so I think I can rule it out. My wife has a Note that I have been drooling over, guess I will have to "borrow" it for "testing" when she gets home from work.
Also, I notice I am on baseband KH7 with Android version 2.3.4. I see mention of KK6 and 2.3.6 on the forums. I have avoided flashing the baseband, when possible, to keep from possibly bricking the unit. Is it possible that upgrading these could resolve the issue?
That is a very weird problem. Only thing I can suggest is compare the APN settings in root with a custom rom's settings. They should be identical, but check anyway.

Then it isn't connecting to 4G networks.
It's labeled as "4g" but really just multiple 3g connections to give you a faster overall speed. But you might want to just try getting a new sim card at your AT&T store, if that doesn't work, try a different modem (like KK6) the whole list/downloads are in the development section.

I made AT&T upgrade me to a n LTE sim card. Our phone disent have LTE but the newer sim cards supposedly will make your speeds faster when LTE does come to your area due to it pushing HSPA+ faster than enhanced backhaul.
You said you live in the center of a big city maybe being surrounded by a lot of tall buildings could be causing havoc on your cell reception.I know at my work I can send and receive messages and calls everywhere except our breakroom but everyone else's phone works fine in the breakroom.

Hi I am currently a T - Mobile customer and when I originally bought my Samsung Galaxy S2 with the company, I thought I could take advantage of using both the T - Mobile network and 2G services of the T - Mobile Orange Network.
However after successfully using it for the first 2 weeks, after my KE7 firmware update, I have an unbranded phone, it did not connect to the network anymore, stating, even if I manually select T - Mobile Orange in GSM mode only, Cannot registor with network, Unable to connect, then it states it is registered and yet I have emergency calls only stated and not either T - Mobile or even T - Mobile Orange. Then it will not connect to either network manually until I restart the phone.
I have since flashed my phone with various other firmwares, am currently on cognition s2 1.13, it's a great Rom, and still the same thing occurs.
I have contacted T - Mobile, they can't fix it, I have took the phone to a Samsung Repairer and they couldn't see anything wrong, stating it was a fault with Orange, as the guy in the shop's T - Mobile branded Galaxy s2 did the same.
Anyone solved the mystery, or is able to explain the issue to me?
It's doing my nut in, I have had phones like these for years, flashed them and enjoyed them, and usually work things out for myself, my last phone was an Samsung I8910, which was great with custom firmware support and I must say the Galaxy s2 is by far my favourite ever phone, but even my Samsung Omnia I8910 works properly on T - Mobile and Orange, and the latest and greatest phone won't!!
Have you tried flashing a different modem? Seeing as the cognition rom is based on I9100XXKG1, I know of a couple of forum members that have had trouble with the KG1 modem, and had to revert to the KF2 modem.
Worth a try? It won't wipe you phone of anything daft either.
List of official modems: http://forum.xda-developers.com/showthread.php?t=1131950
Before you do anything, can you dial*#1234# and just check what phone software is installed?
Thanks for the option Unfortunately I have tried the KE2, KE7, KF2 and KG1 Modems now, none of them have worked. It is really bizaar as the bloody thing works really well on T - Mobile, when there is coverage, plus the 3 and H is great speeds when they are in coverage, it just won't switch to Orange

one moment, I'm on t-mobile aswell.
text YES to 2121.
Homer moment: Doh, you cant text can you?
Just for reference, I'm with Orange and in my network list I have both "Orange" and "Orange and T-Mobile". I can connect to the Orange one fine, but not to the other one. It does switch to T-Mobile sometimes though. I've seen it do it.
Hi again, I have text yes to 2121, and it was working on my phone before. So yours has no issues then?

Unfortunately if I let mine automatically switch network, it switches to emergency calls only if I am out of a t mobile network range, not orange, and it used to switch to orange no problem
Then when it is in emergency calls only, I have to turn it on and off to get it to work at all, as it will not register back to T mobile
My last attempt......when you go into wireless/mobile network settings, is data roaming ticked?

Yes it is, cheers for all your help. It's very frustrating and I can't fathom it out, so cheers for trying yourself
You don't need data roaming ticked in order to use Orange. T-mobile and Orange are both considered 'home' networks.
I'm on T-Mobile without data roaming ticked and it switches automatically to Orange without any issues. Might be worth phoning t-mobile up and seeing if there's some sort of issue with your account.
I installed Lite'ning Rom and found that I couldn't connect to Orange on my unlocked tmobile sim. Turned out that I had the "com.orange.authentication.simcard.permission" apk missing.
Downloaded it here:- http://www.contentsd.nl/apk/SimServicePermission.apk
and installed it with titanium and registered ok on orange.
Hope this helps.

Hiya guys. Sorry to jump on this thread but I am having the same issue as OP. I'd just like to give you an update on what I know so far. It is a nightmare trying to speak to someone at T-Mobile who actually knows whats going on, but I was persistent and got through to an engineer who said that they are having transmitter problems in east anglia and surrounding areas...not sure if you are in that area or not. Unfortunately all the engineer said is that they are working hard to a. figure out what the problem is ang b. fix it! He also could not give me an ETA and said that the only way to get back onto the network is to reboot the phone a couple of times. Not ideal, but I though it was something to do with the VillainRom that I flashed...so here's stupid me flashing stock, bricking/unbricking the phone etc etc only to find out later that its not the phone...on the plus side I have amazing battery life now haha who would have thought ey!
Anyways, hope this information is useful to you all.

It is not a ROM issue - it is a T-Mobile/Orange fault

Absolutely right Steph, it is not ROM related.
T-Mobile have acknowledged that there is a problem with registering T-Mobile customers on T'Orange cell towers.
I've been having this issue for a couple of weeks now (also in East Anglia), and after a lot of perseverance I got transferred to Level 2 support (Technical Support - not Customer Support) last Monday. They said there was a 'rectifier problem' on a mast in Henny Street, near Sudbury, Suffolk at the end of June and it has had a knock-on effect on other masts in the area. It was/is a level 2 priority for fix.
I wasn't happy with that explanation as it happens all over Suffolk!
Still with the issue on Thursday, I called them again and got straight through to Level 2 as they had marked my account as an on-going problem which Customer Support (in the Philippines) couldn't handle.
While explaining in detail the 'Your SIM does not allow you to connect to this network' problem the Guy I was talking to received an internal notification that they were aware of issues registering on T'Orange cells, that they'd known about it for 72 hours, have no idea what is causing it, and no eta to fix.
I've been using a forced connection to T'Orange for the last couple of days (poor T-Mo signal in house which always caused it to hunt for T'Orange anyway). Downside of course is that it won't get a 3G signal when forced into T'Orange mode.
Still happening today so need to give them another prod...
Oh, and I found this thread searching for answers - I don't have a Galaxy S, I have a Desire. Further proof that it isn't ROM related.
I'll update when I find out more from them.
Aaron
Just spoken to them again, problem is still on-going, they are still investigating and looking for more samples of the problem to try and isolate the issue. In light of that I would suggest anyone else having this to phone them and ask for Technical Support and register the fault - the more samples they have, the better chance of getting it resolved.
In other words, they still don't know what's causing it or when they'll fix it.
I got Atrix recently, unlocked and flash Allen #4 ROM, but when I use AT&T WI-FI in Starbuck or Mcdonalds, get message - "You are connected to the internet". But it works for a little while, then disconnect - "ATT Wifi Hot Spot" "Unable to confirm eligibility, please call Customer CARE..." but the WIFI is working very well in my DEFY...I'm using T-moble, someone told me have to transfer to ATT carrier...
Is this only one way to solve the issue? I'm in NY...thx for all ans
You could try different ROMS to see if its a phone or software issue or network issue. Have you used wifi that's not ATT wifi and tried that? It could be a network thing.

I have encountered the same issue. Work recently installed a few AT&T hotspots in our buildings. I called customer care, but they were not much help. Seems if I drop Wifi and re-enable Wifi I get a good connection without the message. I never have this issue when visiting a restaurant next to a FedEx store. Lately, this happens 50% of the time.
-Steve.
Thanks guys...I will try to flash official 4.5.91 SBF...then take a test
I have this issue on a stock ROM on my Galaxy SII Skyrocket. Problem is, it never works no matter how many times I turn wifi off and back on etc. Customer service is clueless.
-This device works fine on any NON ATT hot spot and my wifi at office and home.
-This problem only started about a week ago
-So far I have confirmed this is a problem in Sam's Clubs (2) and Barnes and Noble.
-All AT&T or non AT&T phones that do not have their stupid "Auto-Login" software work without a problem, even my tablet that is WiFi only. Same locations works fine as long as it's not a device with their Auto-Login software crapping things up.
rooted stock atrix on latest rom. same issue.
whatever......
Depending on the store, some have a log in in the browser you have to press a few buttons.

I did do that, but same problem. I'm new to the whole custom ROM thing, and I've noticed that even after doing what you said, it still has issues. Either it will connect, then disconnect, or put the phone into a reboot loop until I leave the area where the ATT wifi is. But, if I revert back to stock 2.3.6, I have no issues. Is there a fix for custom ROMs that I just haven't stumbled across yet?

'Fraid not. CM ROMs are not endorsed by AT&T and so don't support AT&T pecularities. If you want support for AT&T hotspots, you're stuck with stock software or a ROM based on it, for example Nottachtrix or ICSROM or similar.

That's what I was afraid of. I've been trying with Atrics v1.0 and 2.0 with no luck on AT&T hotspots, always sends me into a constant reboot cycle until I leave the hotspot coverage area.
I had this problem running miui, cm7, and now I'm on unnammed. I've used all the modems and still nothing helps. I thought unnammed didn't have this problem? To fix it I haft to flip to airplane mode and back, then its fixed.

Could be APN settings. I don't know them off hand, but they are listed in post 2 of the miui thread.
If it happens on multiple ROMs it could also be a bad SIM card. Does it do it on pure stock? If so, try a new SIM card.

I've had the same thing happen to me on other AOSP roms too. On both the SGS2 and my captivate.
I just switched to iscrewed to see if the prob is still there. Its hard to reproduce the bug, but it happens when i go from either:
1. being connected to wifi for a long time and then leaving that area, mobile data doesnt turn back on
2. being in a bad service area for a long time, and then leaving it, mobile data doesnt turn back on.
The worst thing about it is i use google voice for texts, and thats usually how i can tell that it cut out, because i stop getting texts from people.
I love android and google, but honestly if problems like this dont get ironed out, then as long as the next iphone has a decent size screen im probably switching over.
FYI this has occurred when i had the bare minimum installed on my phone, and i never use any ridiculous battery saving apps.

ill try this out tomorrow. just now when checking my email i had to turn on airplane mode and back off to get data to work.
also, i tried the apn settings on the first page of the miui thread and it didnt work. i tried those settings on miui, wiui, cm7, and unnammed but they all made it so that my internet didnt work at all.
so just to clarify, i shouldnt haft to change apn settings and my phone shouldnt be doing this on non stck roms, right? sim is likely the problem? this has gotten really old really quick and its embarrassing when im trying to show my friends something but my phone isnt working.
Your phone should work fine on any ROM you find here. Mine does. I never have to play with APNs, even on miui. I never have to play with airplane mode or power cycle. But, when my SIM was bad I would drop data connectivity all the time. Calls would fail (outbound only), and other glitchy reception issues. Sometimes airplane mode fixed it, sometimes power cycle, sometimes airplane mode on, power cycle, and all times it was temporary. Its worth a try, shouldn't cost anything to get a new SIM. If they give you trouble at the store just tell them you called 611 and they told you to go in for a new one. If that doesn't fix it go warranty route for a new phone.

Those APN settings have worked fine for me on both CM7 and every Sammy ROM I've used. I always have (unrelated) problems with MIUI, so I can't verify that one.
So i went today and got a new SIM. Its been about 9 hours, but no problems yet. Time will tell if it works, but im willing to bet that was the problem, and this is why.
When i went to get my sim, the guy there told me that when ATT started rolling out 4g phones (which includes 3.5g) many employees had trouble with their data switching on and off until they switched their sim cards.
Then i started thinking to myself - I've had the problem about as long as I had my SGS2, and only had the problem with AOSP roms on my captivate - then i made the connection.
When i used a stock, or stock based rom on my captivate, i had no problems. The second i used an international ROM, or an AOSP rom is when i would have the issues. What is the difference between the roms............. The ATT rom doesnt have hspa+ enabled, so using my old "3g" sim card i was fine. No 3.5g to connect to to cause problems. CM and international Roms would use that new 3.5g network and would then screw up.
That is my theory anyway, and if it turns out true it would have solved one of my biggest annoyances with android. (or at least my android experience)
fingers crossed
i too went in and got a new sim. my phone service actually quit working before going in. id get calls and i could hear them but they couldnt hear me. i replaced the sim and all is good. where miui would hang and data would freeze and id haft to redo the airplane mode trick, it would just hang for a sec or 2 and then start downloading again. ive only had it hang 2x now and i think its because it might be switching from hspa to 3g or even wifi.
so for the sim card thing worked. if it fails in the mean time, ill come back to this and give an update. thanks for suggesting it being the sim card cause i wouldnt have thought of that.
I'm another day strong without any problems. I don't know of its due to the new sim or because i switched to a Samsung based rom. I should switch back to test, but I'm loving the speed of icsrewed right now.
If i had to guess i would say it's due to the sim, and if so, there should be a sticky somewhere that says to make sure your not using an older 3g sim card. Would have saved me months of aggravation.
Will report back after a few more days. In a week or so I'll switch back to cm to see if it fixes it there as well.
That's one reason I generally buy my phones at the att store (authorized reseller, but dedicated to att phones). Usually they will price match, and they know things like that. My SIM went bad when I had my captivate. Later when I upgraded to a faux G phone the att rep knew I would need a new SIM, and replaced it then, even though it was only a month old. They also knew the "3G" data plan needed to be converted to a "4G" (still unlimited) plan on their system for me to get data.
You don't get that kind of assistance when you buy at Walmart, online, etc.

Amazon Mobile just sends you a new simcard anyways lol
Interesting, maybe next time if my data refuses to work I should bug at&t for a new Sim card. I had problems on different roms including stock rom where I had to turn off and on my data or else it will not work. But I think my modem might have played a role. Data seems fine now.

If you go directly to an AT&T store they replace it for free.

Yup just show up. They shouldn't charge. as long as your an att customer theyll take care of you. I've never heard of anyone paying for a new Sim. If you lose your Sim I've heard of them charging people, but i doubt they'll charge even then.
Longtime Sammy ROM (mostly Wanamlite) user here, dabbling now with new 4.3 ROMs based on AOSP, namely Carbon and PA. I like both of these releases and for the most part few problems but one:
The precise moment I start a cellular call, my mobile data connection drops. 3G, H, H+, doesn't matter. As soon as the call is over, the mobile data connection immediately resumes. Sorry if this is a noob question, but am I missing something here? I've played with a number of ro.ril build.prop settings, none of them seemed to influence this behavior a bit.
This is a deal killer for me, I commonly run IM clients and participate in web data conferences while simultaneously making phone calls. This works against AT&T service on the Sammy ROM.

Are you sure you have the GT-i9300 on AT&T and NOT the AT&T version?
I too am on att and use an i9300 not sure but i think the att version would say 4g instead of h+ or 3g. anyway What I do is I always use Stock rooted roms. I alter the default apn to geta much better signal. att does not recognize the I9300 as an sgs3. they frankly do not know what it is . also they do not support it. so they put the phone in the wap cingular default apn. this is also used for their prepaid and dumbphone customers. you can manually change apn settings.to get better data speeds and signal.
I have been researching on this for a few days. It seems like it is a motherboard issue with several GS3s... This sounds stupid, but try to hit the back of your phone really hard.. If the sound is workign for five minutes after doing this, it's most likely a hardware issue, just like mine..
i would think that hitting the back of the phone really hard would most likely cause damage to the motherboard and other microelectronic components. the op has stated that he has problems with his signal while using aosp roms. but the problems disappear on sammy roms. that would indicate that his problem is Not hardware related rather than software or incorrect settings in build prop.
I do believe you when you say you have hardware problems. if you are hitting the back of your phone as you have recommended to the op. it is almost a certainty that you have damaged the fragile internal mechanisms inside your phone.
Yeah! But the problem is that this is a known hardware problem with the S3. It's very annoying cause I love my S3.. Would be a bummer to sell my iphone 5 just to get a new S3.. I was thinking of buying a motherboard and install it myself. I just hope that the fault lies within the motherboard components
well first you need to find out if the problem is hardware related. my suggestion is to get your phone back to stock if it isn't already. then see if you have the same problem. if yes then try factory reset . if that does not work then you probably do have a hardware problem . but it is probably your baseband or antenna rather than your motherboard, also check that your apn settings are correct,
if you decide to send it to a service center do not tell them that you have been hitting your phone, and please don't advise anyone to hit their phone either, these devices are not cheap and hitting them will cause physical damage which is not covered under warranty.
Sure I understand that advicing someone to hit their phone is stupid. But taking from my example I've tried a bunch of ROMs, a bunch of radios. I've also reverted to stock ROM with the same problem.. the audio comes and goes when knocking the phone behind.. I've also tried to reassemble the whole phone myself. I've reattached every wire there is and the problem still persists.. This is a very weird problem
definitely sounds like hardware problem either speaker or wire connection.if the phone is under warranty then send it to samsung. if not then find a reputable repair shop that understands how to fix it. shop around because too many places only know I phones. also you can go for a paid repair from samsung. may cost more but at least you know it will be fixed right.
Thanks all for the replies. First, I have no plans to hit my phone nor do I have the audio issues the other poster hijacked regarding

When you say "stock", do you mean a rooted Samsung ROM?

Worth noting, I do not have LTE enabled on my AT&T plan (I have a grandfathered unlimited iPhone data plan) so can't use the lte or other "4G" APNs out there. I tend to use the wap.cingular APN as none of the other posted alternatives work better (or at all). What APN do you use out of curiosity?
Since my OP, I've also tried SuperNexus 3.0, and saw precisely the same issue. I've fiddled with bringing in applicable ro.ril build.prop settings from Wanamlite's ROM, checked my modem (it's the same between Wanamlite and the AOSP ROM's I've tried, I9300XXEMB6), tried different APN's nothing seems to work.
One thing I haven't tried, is to use a well-established AOSP 4.1 or 4.2 ROM.. may do that later if no other bright ideas come along.
att apn settings
this is what I use. just one apn called PHONE . I am in new York city. I don't know if this will work for you where you are. I am rooted and everything else is stock

Just some info I am in UK using correct APN from provider and I have the same issue on 4.3 roms when on rootbox 4.2.2 I could use internet while on a call hadent noticed that had changed till I seen your thred
Ok, I've had issues with this phone that began with a bad battery. I got a new battery through insurance and my problems continued, even worsened. The phone will lose network connection constantly. It will reboot on it's own or during use. This is the only way it will obtain network connection once lost.... I went to at&t a million times and they flashed it for me a few times, replaced my SIM card three timesthis month and no luck. I decided to be brave and root it with cyanogenmods latest 4.4.2 kitkat (which I love, props to them) and it still continues to do the same crap! It's getting old and im beginning to think it must be a hardware issue, but I read about flashing a modem for the phone. Does anyone know if this might solve the problem or is it likely a hardware malfunction?
It seems to cause the most issues when im not on wifi or when LTE is activated.
Tried the *#*#4636#*#* code to change the connectivity settings but the only option im allowed to use is the lte/gsm auto (PRL).
Any advice is appreciated.... my next option is shooting it with my shotgun and using it as a conversational piece at the office.... maybe a
A paperweight??
thank you for your time.

Could be a modem issue, could be as simple as changing you APN settings. Where is your location? Could be affecting you a bit. Run a search, many have had this issue.

I live in central Arkansas and I'm not exactly sure how to check my APN settings...?? And if it's a common issue based on location, why does AT&T not recommend a solution to anyone with problems? Or do they and I just don't know?
I've ran this phone on straightalk 3g for about a year. Recently upgtaded to a lte sim and loose signal a lot since. Miss calls. Don't get text. I have read certain art lte towers have this problem. Sounds good since my wife's s4 has same problem. Both phones ran fine and got calls on 3g sims

I found the settings directly through the AT&T website but theyb only povide 4G HSPA+ settings.. which are not LTE.
Follow this steps and check if your APN settings match, and if they don't then just create a new profile with the settings in this link:
http://forums.androidcentral.com/go...ogle-nexus-5-t-lte-apns-network-settings.html
Techinically, this settings are stated to be for the Nexus 5, but the APN are carrier based, so regardless if it states Nexus 5 APN settings they would still work for our OG Note
You should be able to get to your settings by going to settings / wireless data & networks ---more / mobile networks --- Access Point Names
Hope this helps!
