[Q] GT-i9000 at&t service disconnects often - Galaxy S I9000 Q&A, Help & Troubleshooting

Hi all,
I recently bought an unlocked international version of samsung galaxy S GT-i9000. I was able to use it with at&t sim card quite happily till now. Even the 3g worked on it. But from yesterday the at&t service keeps disconnecting after using for few hours. The network bars at the top right disappear and a blue disconnected sign appears. I cannot make a call or receive a call till I reboot my phone. In settings->about phone I see that the "Service" shows "Not in Service". When I reboot it gets back to "In Service".
Did anyone face this problem before? Is there any solution for it? My unlocked phone boots with T-mobile preset settings - is this problem because of that?\
Someone please help.

I've been using one on AT&T for quite a while without issue.

Ok. Thats encouraging. Did you change the software on it - like rooting or flashing other ROMS or still using the original touchwiz?
I donno why I am getting this error now..it worked fine last week.

I've flash several roms without issue.
Did you install anything recently before the problems occurred?

I just installed a Yahoo mail application and some online radios yesterday. Nothing on the software side like rooting or flashing. I am still using the samsung touchwiz that came with the device.

Looks like that yahoo mail app is the cause of the problem. Deleted that app 1 day back, and it seems to work smoothly for now without any disconnections. Thanks for pointing out to look at newly installed apps.

did you buy I9000 or I9000M ?
I9000 runs on 900/1900/2100
AT&T runs on 850/1900
I9000M runs on 850/1900/2100

Doesn't really matter I had stock/euro i9000and had no disconnects.. although sometimes I only got edge when there was no 850 3g. I now have i9000m and still get no disconnects.. and yes I am on at&t.

I bought I9000 (not the M version). I am able to get the 3g HSDPA with 1900 frequency. I verified it online before buying the piece that 3g would run on one of the frequencies. The problem I had earlier was not with the 3g network, but with the actual cell phone signal which enables to make calls.

I had this problem for a while after I flashed one of the firmwares.. the fix i think i used was to change the settings on the phone from KOR to BMC.. I forget how to do this..
it was one of the *#1234#* type codes.. Anyone remember?

I guess I was early in thinking everything is alright. The problem started again- it gets disconnected once in a while and I have to restart the mobile. Hey dapoktan, can you please remember what you did earlier to get rid of it? If we change the firmware does it help? I am waiting for samsung's android 2.2 update, hope they at least release it by Nov 11th (as mentioned in one website)

Thanks every one for your suggestions.
Before applying nailer's suggestions, I just saw I could update the firmware to froyo by doing a registry hack in kies http://forum.xda-developers.com/wiki/index.php?title=Samsung_Galaxy_S_Series#Installing_firmware_for_different_country. So just gave it a try and currently got froyo.
Have been using froyo since yesterday and no recurrence of the problem till now. I also successfully rooted the device following http://samsunggalaxysforums.com/showthread.php/2384-Rooting-FroYo-2.2 and applied Ryanza's lagfix 2.0 available in market. Looks fine for now and the phone runs excellently smooth.

WEIRD! Emergency call only! O_o

This one is pretty *beep* up! The phone was working pretty fine last time I looked at it (30 minutes ago), I put it in my pocket and had dinner (as always), then I took it out to make a phone call and it says just "Emergency call only" instead of showing my phone operator (3 ITA). I tried rebooting, no luck! Still the same.
Strange thing is that it has signal (full) but I can't make/receive calls or use data network. If I go under Settings -> Wifi -> Mobile networks settings and I look for operators it searches and I can see all of them (mine included) but I cannot select it!! Neither mine nor another one (TIM, which is the roaming default one for my operator when there's no signal)...it just says "Unable to connect. Try later".
Weirdest thing of all is that I AM RECEIVING PUSH EMAILS from gmail!!!
Anyone has a clue about this??? Has it ever happened to anyone?
Btw, I'm using zeroblaster rom, which is based on official italian froyo firmware...everything was working so good until ten minutes ago!
Hope I don't have to reflash...
Just got weirder: put my sim on another phone...it registers without problems on the network.
Then put the other's phone's sim on my sgs...it registers without problems.
Then switched again: Emergency calls only
WHAT THE ****??!? (what are we? children? sorry mod...lol)

Sounds like it may be ur sim card but its weird it would work in another phone. Perhaps its a mix of ur sim and ur rom. A flash may be ur only fix...

It is WAY weird imho! The weirdest thing being that I'm still receiving gmail's pushes after 5-6 reboots while it keeps saying "emergency calls only".
Also I saw that when the phone boots, while it's loading the launcher, widgets, etc. it gets the connection for like 2-3 seconds it shows my operator (in the lockscreen), then it switches to "emergency calls only"...
I'll wait another hour (maybe as the issue came out of nowhere it'll go away? ) then I'll try reflashing...since I had to change to k9 anyway to fix the /system corruption etc. -.- I'm already backing-up...
Hope the flash will fix this though...it's really a pain in the ***

No that's not it, because putting H3G sim on another phone WORKS!!
And anyway, when H3G's down it uses TIM as roaming...this time I cannot even select TIM as operator, it refuses! And normally you can always use tim in roaming if you want (even when H3G has signal...)!

Hmmmm... That is weird alright.
If you purchased your SGS through your carrier H3G I would still call them to report it as there are now 2 of you experiencing the same issue so it cant just be phone related and if it is then they will have to honor your warranty to replace or fix it (both of you)...
It's happening to me too.. i also use H3G Italy on my Galaxy S and i have this issue since around 19:00 this evening with my work SIM card
I have a Tayutama 1.0.0 ROM based on the JPM Froyo ROM.. it's the first time this is happening to me..

Well... That is 3 of you so it must be carrier related in some way. Again... Call your carrier and explain what is happening. Explain that when you put the sim into a different device it works ok but in the SGS all you can do is make emergency calls and they should be able to tell you what is going on.
Make sure to post back as I am now interested in seeing what your issue is / was...

mobile network state: connected (and it works... )
but ... int the status bar it shows "Only emergency calls"...

You just answered your own question I think. "service state: out of service" says it all I believe even if the sim cards DO rgister on another phone for whatever reason.
The fact is the they dont register on your Galaxy S so call them and report the issue and they should be able to help you...
Yeah well, you see, that could be a problem because...H3G has a TERRIBLE customer care, lol! Basically the thing is you can't call them...you need to send an email, and an answer will arrive 2-3 days later. That's not good enough for me! If it doesn't get fixed tomorrow I'll go directly to a 3shop and they'll call someone higher to understand this. Hope they fix it soon though!
Anyway...now I have a strong curiosity: could it be JUST the SGS? If so...WHY???? I tried putting the simcard on a Nokia E71 and it works...does anyone have another android phone with H3G? Could it be somehow "system"-related? Because I can't figure out why a specific phone device shouldn't work point-blank with my operator! And that's even a phone they sell themselves!!
Rebooted and now it WORKS! THANK GOD (even if I'm atheist....)
Still would like to know why it did this!
I had a similar problem where if I was in an area with bad reception it would default to emergency calls only. But the funny thing is when I go into the menu settings I can see my carrier and when I try to select it, it says network unreachable. Eventually I would get signal but the tab still says emergency calls only. Tried making calls but it wouldn't allow.
Initially to rectify the problem I rebooted the phone and that worked but got annoying. So I realised that if I left it for a couple of mins whenn it had reception it would fix itself. As of recently (last 2 months) I haven't any problems.
Btw i'm on jpm and my carrier is 3 australia. It's rubbish service

Hello,
Same thing happening to me... It must have something related to signal strength, i went downtown and phone was perfectly fine.
But at home it keeps loosing signal, i dialed *#*#0011#*#* and it shows changing BAND... as if it was searching for service on different bands...
But the thing is, i tried inserting the SIM on other 2 phones and i get a FULL signal, so i guess signal is coming pretty intense here... why is the SGS loosing it? i have no idea...
By the way, i am from Brazil, and that started happening after i flashed my rom to FROYO VJJPA..
me too, has no signal at home but works for another phone.

Same is happening to me. Serive state says out of service so could registering the sim card to phone be the actual isuue?

[Q] My Note cannot make/receive phone calls anymore :(

I think my N7000 is broken. Since a couple of days I cannot make or receive phone calls with my SIM card from the carrier 3 (Three Sweden). I've tried two different SIM cards from 3 but it's the same problem. Data traffic still works though since I can surf the Internet without problem. When trying to make a phone call it immediately hangs up, and if I try to make a call to the phone it's unreachable. My phone is unbranded/unlocked BTW.
I've tested with SIM cards from two other carriers and they both work.
The only think I can think of is that 3G voice calls are somehow broken on my N7000. My carrier only supports 3G and maybe that's what's broken... what do you think? (the other cards I tested also supports 2G and maybe that's the reason they worked, but I'm not sure).
Brgds... /Tubgirl
I think your issue is the same as mine, though to clarify my issue somewhat:
When the phone does this and I try to make a call it doesn't hang up, it kinds of gets stuck and keeps waiting for the back-end to respond. Similarly, trying to send or receive SMS messages doesn't work either. Rebooting fixes this, though it may happen again quite soon or it may take several days to happen again.
I think it is some background-process related to radio operation getting stuck, though I cannot say what causes it. Factory reset and even full reformat and reset had no effect.
I hope ICS fixes the issue.
What I've tried so far is:
Full wipe - No change
Next step will be to visit my carrier store downtown and test yet another SIM card from them. If that doesn't work I guess I'll have to get it repaired.
Oh yes... I tried another card from another carrier (Telenor) and changed Network Mode from "GSM/WCDMA (Auto mode)" to "WCDMA only" and it still worked. So now I'm not sure why it doesn't work on Tre ?!?
/Tubgirl
Update: Got a new SIM card from Three but unfortunately it didn't help. Tomorrow I'll send my phone to get repaired :-(
Brgds... Tubgirl
i got the same problem but is t mobile uk, "Data traffic still works though since I can surf the Internet without problem. When trying to make a phone call it immediately hangs up" I tried others sim vodafone, o2 both work without problem.
Factory reset, different stock roms no help...
Yep, same here. I just downgraded to KK4 stock ROM using Odin and it still didn't help.
Cannot send/receive SMS either.
Brgds... /Tubgirl
I guess I have a Galaxy Tab 5.3 now
/Tubgirl
I have a similar issue, some times i cant call and receaved calls ends few seconds after hanging up.
Sent from my GT-N7000 using XDA
i give up, i changed the network providers to 3 network everythings back to normal.
I can't find the link right now but I read somewhere that there's a hidden area on the phone where IMEI and other carries specific information is stored. As I understand that area is not restored when flashing ROMs. Maybe there's a chance that area has been corrupted??
Brgds... /Tubgirl
In my case , I cannot receive call - I believe it is software issue.
Is there any workaround how to fix it ?

Have you checked that your IMEI is fine (matches the one in the box or the one below the battery)?
i doubt its software issue, i also thought that i was having a software issue, after so many roms that i tried flashing, same result. stock or customized. I went to samsung service center and they had it tested, replaced the board that has to do with the antenna, and now everything is working properly.
same issue i have checked imei with the box and it ok, i can connect to 3G but can't make call only emergency call.
tried CSC Change

Galaxy S Advance Network Issues

Hi,
I got s advance for my wife 2 weeks ago thinking its the best sub 20k handset in india at the moment. First 2 weeks all was well. But since last 3 days she has been complaining about network loss issues as reported by all here. I even tested it yesterday and put it to gsm only mode. But it seems its still there.
Any body here facing this issue? I googled this and it seems there are a lot of people complaining about the same.

Yes all facing the same problem with galaxy s advance in India. The issue diminishes if you switch to GSM only mode by disabling 3G..
All of us should call and flood samsung with complaints. As of now they are pretending that no issue exists with the phone, despite numerous complaints on their own offiicial website.
Yup today I'm also having this problem ....what the hell...the basic feature of phone connectivity is hampered....
Guys there's new kernel version for those having network and battery issues kindly update your device from settings software update ...new kernel 6mb....kindly enjoy the beast now...who couldn't due to batteryy network and lag issues
Ok guys..what I'm writing plz copy and paste to every blog you know of s advance so that people come to know the reality of network error...first of all...there's no network error on this phone...no come to the topic why we get network error than...ok..in India we have 2 types of network one Gsm and one cdma...and those guys who used Android before..and flashed different countries baseband.remember we had new options in network...not cdma or Gsm we had use 2g only...but this phone with Indian baseband has cdma or Gsm...now we all know cdma service like reliance tata indicom and all..if you use that than put phone on cdma mode...otherwise put on Gsm mode..if you using 3g on Gsm or cdma doesn't matter...add some guy asked me that he using 3g so he put it on auto mode...in auto mode your phone connects to Gsm and calls again after call it's search for both cdma and Gsm network but your sin doesn't support cdma bands so network error again now your phone tries for Gsm and locks your phone...but after some time again it searches for cdma...and of you want to check your phone than put your phone only on cdma mode and try to call...you'll get error msg...network not found...guys relax there's no bug..it's just we were confused...and there's lack of communication between the Korean company with real developers and Samsung care..idiots...actually not there fault...they are just dummies ...they've been told to format flash and of world good otherwise send to head office...do guys all doubts clear..and the who sold there phones...the phone wasn't meant for you and kindly mail to that guy who's signing the refund in Samsung that he should communicate with Korean devs and try to learn what's the real problem and we're it is....guys I guess I I've cleared all doubts...regarding network error...which wasn't there...keep smiling keep enjoying the beautiful gift of life...
This is something happens with almost all android devices with 3G... Maybe.... Because even i face this problem on my galaxy ace plus...

it's true... one thing that might help is to turn network on/off a few times in order to get it working properly again... that's what i do... it doesnt work everytime but it's better than nothing, right?

[Q] Internet Connection Problem

Hi everybody.. I ordered a Droid 4 from the US (i'm in the UK) .. Setup giffgaff unltimited internet, however for some reason the connection isn't stable. Sometimes the connection will not connect for at least 3 hours. I have rooted and tried the AOPK, Avatar and Liquid ROMs, but its the same issue.
I have another Droid 4 running 4.0.4 and tested if it was a problem with the SIM card, but it worked fine.. No problems what-so-ever.
Any suggestions anyone?

I eventually gave up on giffgaff because of constantly dropped calls, and incoming calls that would go straight to voicemail. Found it a lot better on O2, which is odd given that both use the same network.
For your problem though, how is it if you use the stock ROM? all those 3 ROMs use custom kernels and I haven't had much luck with them on GSM. If it works on stock then you know the problem isn't the phone or the SIM at least.

I have noticed some of your old posts in the GiffGaff Community Forum.
FWIW, I've been using it in anger for just over a month, and can't say I've had any problems (apart from a short outage across the network, which is apparently quite rare).
Cheers,
Steve.

Yea the problem is persistent on the stock ROM too
Is there any way to calibrate the hardware?
Not that I know of, mine just worked.
Did you update to JB yet? I believe there were changes to the radio firmware included.
Other than that, I don't know. If you have an identical Droid 4 that does work with that SIM then the only explanation left would be faulty hardware
Yea it came originally with JB
Can you tell me how to downgrade to 4.0.4 if you don't mind please.

AFAIK - You can't downgrade, I'm afraid.
In the Network Mode, have you selected GSM/UMTS, or are you set to Global?
It does sound like you might have a hardware problem.

Thanks everyone, but I found a solution ~ a very weird one...
I removed all the custom ROMs and safestrap and did a full factory reset on the stock ROM. Miraculously this did the trick strangely enough.

[Q] N7000 3G Radio failing

I've had my GT-N7000 for about a year. It has been rooted and running various ROMs since I had it and has always worked wonderfully. I had settled on CM 10.1 about a month ago. Since the last 3-4 days I noticed that my 3G signal showed no bars from time to time. Normally, just a quick 'airplane mode' dip and everything would be fine.
2 days ago was still having the same problem and I had to completely turn off and on again to 'maybe' get a signal. If I got a signal, it would only stay there for a few minutes and then disappear.
I changed the SIM card yesterday just to be sure but I still had the same problem. The same SIM card works perfectly well in my GT-I9000 running CM 10.1 as well.
I cleaned the SIM slot contacts, verified the internal antenna wire and even flashed a few modems and still have short lived and intermittent 3G signal. Any idea about what could be happening? Could it be the 3G radio failing on me?
Thanks for any help.

Anyone?
Does this happen after you move from one area to another? For instance from work to home or Vice Versa?
same problem
Hi there,
I've got the same problem than you. I got my Note 1 year ago, and since few days, I've a problem with the SIM.
On boot or reboot, the SIM is perfectly recognized and works good. I can call without problem, and can connect to the wifi without problem. The problem is when I use 3g, the SIM is not recognize after 1-2 minutes. I mean, I can access internet, do whatever I want, for just a minute or two. After that, the signal drop instantly. I tried:
plane mode: doesn't come back to normal mode cause the phone says there no SIM card
change modem: don't resolve the problem on all XX*** modem for JellyBean
change ROM: I was on German-leaked 4.1.2 Stock ROM, i tried 4.1.2 Switzerland ROM (where I live), 4.1.2 custom ROM and cynogenmod 10.1 (4.2.2). Always the same problem.
Tonight I'll try another SIM in the phone, in the case that the SIM is the problem.
otherwise, I don't know what else to try...

You're ****ed if it's the same problem! I tried a lot of technique and the one I warn you about is changing the RIL. Useless waste of time and ****ed up everything. At the end I tried an app available on the play store for thé modem, can't remember which one. But hey, you're on the track!
Good luck

Are you sure it is the radio causing the problem and not the antenna? I know on mine, the USB charge port can be a real PITA when it
goes bad, and I had to buy about 3 before I found one that worked properly. With the wrong one, the radio signal would fluctuate all
over the place, so that's why I wonder if it could be a bad antenna/connection/board problem, since it is contained on the same
board as the USB port?

I had an update..
I figured out that when i change the network mode to GSM ONLY it runs very well and never drops network signal or get the NO SIMCARD message..
but when i change the mode to AUTO or 3G/CDMA it drops network and gets NO SIM CARD after a few minutes !!
still don't know the reason & still searching
Let's talk about this problem. Mine is similar. Not getting errors with aim card but when i place or receive calls while in wcdma mode, conversation is normal at first place, then after few seconds i can not hear other side, and other side cannot hear me, sometimes that call ends and that is it. On gsm only, calls work normally, but internet is not working, while in wcdma internet works... pretty nasty issue. I tried flashing different roms, tried several modems to flash, problem is not disappearing, but from modem to modem i can see improvements. Sometimes it does not drop at all... can you help me with this?
