[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.

[Q] No GSM signal after doing Factory Reset!!!

Hello everyone, I've a member of this great forum for long time sing HTC HD2.
Recently, I have upgraded my phone from Sensation to Galaxy Note yesterday. I did check everything from store and it work fine. However, After I get home. I have tied to do "Factory Reset" then the phone got no GSM signal.. when I do check with *#*#4636#*#* it say "Unknown" in Radio mode (the icon on top of screen it look like "Not parking" road sign with out "P").
The only I can get the GSM signal back is taking the battery out for 5 mins then put it back.
Also it will getting worst if I do try to enable "Airplane Mode". because it will make phone unable to get out from "Airplane Mode". Only way is take battery out.
Please... Anyone give me feedback on this, I'm not sure it Hardware or software problem. If it hardware... I have to exchange it with it a week.
Thank you very much in advence
PS: I from Thailand user. I thinked the software on phone is Asia version

Try select network operator manually, n also check network mode (select Auto).
from setting - wireless-mobile networks

Thank you for your replied. I have tried everything and no luck. So today I went to service centre and asked them to check it. They said it's hardware problem and arange exchange for a new one. Sadly it's current out of stock @ the shop I bourght so I have to wait for a few day to get a new one.

Try reflashing via odin. Could be just an unknown baseband.

Your have to rest it to factory and keep SIM inside when I turns back on and wait for little while, I happened to me too. and this trick worked.

Do I ever take the Sim card out and put it back in then reset the phone ...or just leave it in and factory reset ?? Thanks for the help
Sent from THE GALAXY NOTE 3 !

So I'm having this same issue. I personally have been fighting it with each update and spent hours on the phone since launch with AT&T and LG. Today when i contacted AT&T they transferred me to LG to see what could be done. The moment that tech got on the phone he said it was a known issue and it had to be sent in to be repaired. Unfortunately the AT&T DSC can no longer flash LG phones or I would have gone that route. It looks like LG messed up on this one for devices (look at their webpage and you will see 2 AT&T D950). Personally I'm looking into other options to see if anything else is available.
EDIT : I tried the return to stock method and both times it continues to say not registered. Guess its going back to LG for reflashing..

This stinks! Did u mess with similar card at all?

I tried changing sim cards, changing the date, multiple factory resets, everything that both companies wanted me to do. Even contacted lg 3 times in the course of 2 months for them to finally say it was a known issue. From various other threads and pages im seeing it happen on different lg phones as well.
EDIT: Contacted ATT Chat support again today to try to have them push the update to me, after finally explaining to him that he was looking at the wrong phone (every agent has done this since this issue has come up) he checked my provisioning and created a case to have my bjorked Update provisioning fixed. Might be something you all will want to have them look into.

Factory reset worked for me. I didn't get the not registered message after the reset.

I have that same issue the phone is not registered yet problem the only think would help to update the phone to kikat its finding the TOT and dll file and make the update via de lg flash tool but at this time no one have those files yet

hi i have had that issue with lg g2 and what i did was go to ATT outlet or whatever carrier you may have and ask for a new sim. put the new sim in and do a wipe everything....it sucks but must be done. when your phone restarts update everything as it should and check your software update and it should be working. that method has helped a bunch of people even in the g2 forums.
hope you all get the problem sorted.

Need help BFR a GS5 for my dad!

Hi, my father purchased a galaxy gs5 from a coworker and I have gone through a lot of bypass factory reset videos from YouTube and it still does not let me reset the device, as the person who he bought it from did not remember the email and password they used when they set it up.
I've used PNY flash drive, uploaded the file to let me get to the setting, then followe'd everything to the T. When I get to the final Reset Device button, i click it and NOTHING. Step dad keeps asking if I got his phone working yet. Still waiting on help from the World. He does not have a Smartphone. He has an old Blackberry, and wants to be able to join our world.
Please help.
