[Q] GT-i9000 at&t service disconnects often

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...

JP5 (i tried another one, don't remember what version but it's the same, it is not firmware related)
in settings->about phone->status it says:
network: 3 ITA
mobile network type: UMTS
service state: out of service
mobile network state: connected (and it works... )
but ... int the status bar it shows "Only emergency calls"...
i haven't tried another phone yet... will do now...
edit: tried my sim on another phone and another sim on my phone.... it works....wtf?

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.

Maybe data is disabled? Try enabling it. Call your provider maybe something is wrong with them?

If you just got this new then simply take it back to the shop.

If you bought it over the internet...try flashing it with the right firmware for the location where you are at...Perhaps LGE Mobile Modem or whatever it is called, like iPhone's baseband has a problem connecting to the network provider, due to the configuration or firmware. But in most cases the problem is in KISS- keep it simple silly...and from my experience it is the problem with the network provider or SIM. Try the sim card in another 3G capable mobile phone if it works o another phone that it is not the sim card. After that reset to factory defaults your Optimus 4X and put in the card. Do not jailbrake-root it. Just test it with the sim card. If that does not help, upgrade or reflash the firmware. If you need assistance. mail me.
I hope it helps. Good luck.

We have a SIM tool kit that might helps. It's one of the apps.

SOLVED
1st i tried every thing i know
i called my carrier (Vodafone) and they stated that it is a Mobile phone problem after we tried all troubleshooting they suggested including adding the APN manually and etc. then i contacted LG middle east to help me and they couldnt help either
finally one of the Vodafone technical team called me and informed me that this is a known issue from their side and we configured the APN with different type and it worked

similar problem!!
I have a similar issue as the original poster.
I got my Optimus 4X HD about 2 months ago. Everything was working fine until a few weeks ago (I think it happened after an update I got)..my phone would just randomly loses connection to the network (no data, no text messaging, no calling). I tried turning airplane mode on and off and also tried to have the phone search for networks and they didn't work. The only solution is to reboot the phone. This is happening at least twice a day... I tried my sim on another phone and didn't have any issues so I don't think it's a carrier problem.
I also did a factory reset but problem still persists.
My phone's software version is LG-P880-V10d-OCT-16-2012
Kernel version 2.6.39.4
Baseband version L6260_MODEM_SIC_02.1216.01
Build number IML74K
Android version 4.0.3
Anyone have any idea how to fix this without rooting the phone???
Thanks in advance!

I have new mainboard replaced by warranty and 3G mobile data not working to, I've tried another carrier sim and there's no issues It must be truth that is something wrong with automatic APN settings...

[HELP] Can't Make Calls, Send Texts or use 3G!!

Recently I haven't been able to make calls, send texts or use 3G despite the fact I have full signal. I have tried both networks (WCDMA and GSM). When I first turn on the phone it says "not registered on network". As far as I'm concerned this started for no apparent reason. I'm on DMod V5 and I have been for the past few months and this started a few days ago. I haven't flashed anything strange or installed any dodgy third party apps so like I said earlier this is happening for no apparent reason. I've tried multiple things including things like reinstalling the ROM but still nothing. I'm using Vodafone UK on a GT-I8190N. Anyone else having the same problem?

Yeah already tried it. Still nothing. Took it into Phones4U today and let them fiddle with it. After about an hour we still had no luck. So they're gonna have to send it away to get repaired and I won't see it until next Tuesday But thanks for replying, I appreciate it
