you could use ( one click unlock ) not very hard two do,just save efs files then click unlock, one thing though if u are on froyo 2.1 click the the froyo 2.1 option or 2.2 if you on 2.2 froyo,but i think you need root to use this program (mite be wrong)
anyway good luck
it depends on the model of the galaxy s. In most cases, you will need to root the phone.
Help Pls
I had successfully unlocked my galaxy s using the procedure suggested on the related XDA forum.. the phone worked fine with a different network later on i accidently clicked the factory reset option.. now although the phone says its unlocked but i cannot see any network signal and the phone does not work on any sim card.
Pls can someone help
PS: I can switch on the phone and perform all other functions.
Try the one click unlock app thingy again, see how that pans out.
Also try this:
Go into settings > network and coonections > mobile networks > and manually choose your provider.
Mine is locked to my network also, but I'm now running Gingerbread. Any way I can get an unlock?

hi all
i thought i would attempt to flash my samsung s with the new beta froyo update.
i followed this guys tutorial.
( cant link to it sorry its the noobs guide with detailed instructions through kies and odin)
i used the odin approach
i managed to root the phone.
on reboot it asked for an unlock code (o2 uk) so i went on to try and follow the steps about unlocking it. which neither worked all the way through the steps.
on reboot it appears to have signal and in the about section it says i am onnected to the o2 network but when i try to make a call is says "data network not available with an ok button, which when pressed will return you to the ome screen.
any help would be greatly appreciated thanks
Almost the same problem,
installed 2.2 update successfully, the phone worked for like 3-4 days very well and after that today i discovered "Emergency calls only"
so the question now is did i bought phone which later was reported stolen? or somehow i broke it?
Anyone have any idea?
hmmm, I have the same problem! In the status menu, the number is shown, but the network, says "unknown"
Hi! I have this exact same problem except I was unlocking my phone using this tutorial:
http://forum.xda-developers.com/showthread.php?t=906255
But I didn't back up my Efs folder, now my phone is unlocked but when I put a sim card in it I have very little network and when I try to make a call I get " NO DATA NETWORK AVAILABLE".
I've tried everything but I don't know what to do!
I was thinking of two ways to fix it:
1. Reinstall froyo (not quite sure how using the samsung software as my laptop oesn't recognised the phone as a pone)
2. Downgrade to, get unlock code using market app and then upgrade to froyo again.
I know I messed up but now I really need to fix this.
Can someone PLEASE PLEASE help me out.

might need to change the modem in odin i think. just heard about it
did u try restarting the phone... just a wild guess...
I had the same issue before and was puzzled. Its actually a very simple solution:
1. Re-lock your phone, search through xda there is a code you have to enter
2. Unlock your phone
All done! Surprisingly easy
Try the Odin method in block 2 back to Eclair if ok then upgrade to Froyo .
http://forum.xda-developers.com/showthread.php?t=818556
However your non connection might be due to not flashing a firmware with your network settings in which case manual settings of APN .
If your IMEI has changed due to flashing and you did not back up your EFS folder then little hope but do a google / search of XDA as some have reported success .

Emergency calls only
I had a custom rom that was giving that to me too. I think it means that you can access a network different from your sim (because usually emerg calls can be made from any phone I think?).
I'd try and find a rom that is optimized for your carrier or at least a modem file from a stock rom that is for your carrier. You may also need to reselect the APN settings (or enter them for your carrier). Its under settings/wireless and network/Mobile networks/access point names (use the menu button to add an APN).
you could also try re downloading and flashing the rom to make sure that is the issue. Mine said it installed OK but never booted up, redownloaded and reflashed and then it was fine but the install screens looked identical.

Hi! Thank you so much for everyone's replies!
My IMEI isn't changed and someone helped me check my efs files and they are all ok. I'm going to try and reflash froyo through the samsung software to see if the network lock comes back and then try to unlock again. For this I'm going to unroot the phone and follow samsungs' instructions.
I'm afraid to relock the phone as there are reports that say it completely messes everything up!
But I'll keep you guys posted! Wish me luck!!!!
PS. Any other suggestions are more than welcome!
So, a quick update on my situation.
I uninstalled busybox and unrooted my phone using the oneclick root tool.
Did a factory format and, surprise surprise, my phone now works perfectly!
Apart from the fact that it doesn't connect to kies, but that's a whole another issue!
Tank you so much to all of you who answered my cry for help!

Can anyone help i have upgraded my phone after much trouble trying to unlock it via market apps & superoneclick neither worked and the phone ended up going into some dead mode and wouldnt fully load up.
So in still trying to end up with a network unlocked phone i have managed to upgrade my phone to GINGERBREAD.XXJVQ 2.3.4 which was successful and work perfectly over my broadband wireless network but when i try to make calls it tell me
"MOBILE NETWORK NOT AVAILABLE"
the mobile was previously on three uk network but is now debranded obviously with gingerbread
i tried a hard reset via *2767*3855* but still no change.
any help greatly appreciated many thanks in advance

Just look like your phone have been locked on three network.and your unlock is failed.
Did you try found any phone shop on market to unlock your phone?
probably just five pound for each one on Chinatown.
I was stay in UK for 3 year,and as I know, the Chinatown guys have special device for unlock phone ,one simply for all,whatever you upgrade rom,you will be never locked again.
I'm not sure about that really cause it also does this with my correct network sim card still installed......
You've checked your apn settings? Sounds top suspect to me.
If you've still got problems, flash ezbase gingerbread. Search dev section, full, simple instructions included.
I tried that it tells me i should
"insert a sim card to access network services"
Could you point me in the right direction so i know im using the right programs and files
Please check your IMEI number by dialing *#06# on the keypad. If it displays the correct imei number as displayed on the Phone box/ under the battery, then you are saved. If not you have lost your efs folder which contains the files which hold the imei data.
Did u get the phone with Gingerbread as stock rom? Try downgrading to an Eclair (2.1) ROM with Odin.
hello again peoples,
I'm very grateful for all your assistance but i just wasn't paying attention when i was putting my SIM card into my phone and put it in the wrong way round...!
i mean what happened to SIM card slots where sim cards only fit in one way...!
again thanks alot for all your assistance also i've ended up upgrading to Insanity 2.3.5
Thank s
I bought SGS from 2nd hand for my girlfriend. Seller said that phone is locked for Virgin (UK). I successfully removed simlock from my SGS (O2) before so i thougt that shouldn't be a problem for me now. But it is.
I checked with *#7465625# that simlock and all other locks are OFF (before i used phone with SIM). When I put any other SIMs than Virgin I get "Emergency calls only" message. Virgin SIM cards work perfect.
I tried remove lock (but there is no lock ???) with all methods from this forum and still have no reception with non Virgin SIM. I checkd 2.1, 2.2.1, and 2.3.4 stock roms and is same.
How I can resolve my problem?
Its possible if u have been using Odin that you have changed the CSC file, which is the modem, which receives signal. Does Virgin receive a signal ?
Yes, Virgin recive signal. Problem was before I flash any rom by odin.
I can see signal bars when non virgin but can't make call. Only emergency.
Maybe I can use some files from my unlocked and working mobile?
Ok, go here http://www.samfirmware.com/apps/profile/76570387/
You will need to register free, and you will loose root but thats easy sorted, download the latest 2.2 for the i9000 and flash it with Odin. Let me know if it helps, and be carefull with Odin, read all instructions carefully. Though i think the 2.2 is just one file, there for it goes into PDA in Odin.
You may also be sim-locked again, im unsure and im no expert at this. Or theres another site that helped me out. http://www.theandroidsoul.com/xxjvp-android-2-3-4-firmware-galaxy-s-install-and-download/
Then go here to root http://www.theandroidsoul.com/root-xxjvp-firmware/
Let me know how u get on

I try to use few firmwares but it not change anything. I think that might be problem with nv_data.bin file. In my opinion someone try remove lock, failed, forgot to backup file and sold mobile to 2nd hand shop.
I have another full working sgs. Maybe I can copy some files and/or edit in hex editor?
Edit
Maybe someone can share me his nv_data.bin from locked or unlocked Virgin mobile please?
Sorry about link, but thats the site for the official firmwares from Samsung. I cant help you with copying files man, I know nothing about it.
Hi,
I have unlocked the att tab long time ago and it was working fine. Then since few days i am messing around with different roms and modems and now my sim is not recognized. Does it means i have locked the device to att because of lot of flashing. Can someone please tell how to check if the att tab is still unlocked or locked. Maybe sim is not working because of wrong rom or modem. Sim working fine in my iphone. I was on rotohammer rom when tab worked like phone then flashed 2.3.3 and lost phone capability. Still has phone icon on the tab. Please need fix.
Thanks,
Hi Tabing.
It is me again.
Are you back on Roto rom now? or in one of the GB rom?
It seems only HyperDroid Androidmeda has the remark by the dev that it has roto unlock commands built in. With that, I assume unlocking is not a permanent thing?
well in my case I went to setting than network then mobile network and changed it to gsm and my cim has been recognized again by the system
just to let you know I was on froyo and I upgraded my tab to 2.3.3
good luck

Hello guys, i'm new in this forum.
I've recently bought a used Samsung Galaxy Note, factory unlocked. It came with the 2.3.6 version of android and it worked perfectly. But today, i've upgraded it to ICS by KIES (i'm a mac user) and it doesn't recognize my sim card (It says emergency calls only). The phone isn't blocked and it works perfectly, except from that.
I've tried factory resets and everything, and it doesn't work.
Then, i've downgraded it to 2.3.6 again and guest what: IT WORKS!
But then, i upgrade it again to ICS and it doesn't work again. It's not a sim card problem, i've tried another ones and they don't work neither.
Please help me asap, i'm in 2.3.6 now because that's the only way to call in my phone...
Regards from Sevilla, Spain.

There are some threads abt sim unlock in "general" section if I am not wrong..just go through it & u should be able to make your sim work on ICS..
Lol for galaxy s unlock in the play store
Sent from my GT-N7000 using xda premium
lol, when you boot in ICS do you get the sim pin unlock screen?
cause if you dont there is a fix for that which has nothing to with being locked.
