I am trying to unlock my AT&T Samsung Captivate and I have followed the instructions in the reference thread for unlock/unfreeze for all SGS models. I tried both methods with SGS Unlock and ADB, as they both are supposed to do the same thing and as a result I got the same unlock and unfreeze pins.
After I got the unlock code I restarted my phone with a Fido Sim card but my phone doesn't ask me for a Sim network unlock pin and it just loads the desktop. My Sim card works in my other phones, so it can't be something wrong with my Sim. I also borrowed my sister's Fido Sim and still my phone does not ask for the unlock pin on start up and displays the there is no sim card in phone screen.
I'm hoping its not something wrong with the phone's Sim slot.
Does the Fido sim work in your phone?
It is possible that Fido is an authorized sim in addition to the AT&T sim.
Hello,
I have the same problem with my mobile. It is a toshiba TG01. Did you solve you problem?
Kinds Regards
I have been looking around the internet on how to unlock this tab (both English and Japanese websites) and I have came across this:
http://berorin.blog.shinobi.jp/Entry/1489/
According to this blogger, he unlocked his tablet by doing the following:
1. (本来使えないキャリアのSIMが刺さってる状態で)*7465625*638*#に電話
2. 使いたいSIMのMCC/MNCを入力(SBなら440/20)
3. ControlKeyに97286414
4. Unlock Saccessfull!的なメッセージが出たら再起動
5. 刺してあったSIMが認識される=アンロック完了
Translation
1. (With another carrier's sim card in the tablet) dial *7465625*638*#
2. Enter the sim card's MCC/MNC (For softbank it would be 440/20)
3. Enter 97286414 on the control key blank
4. A message like "Unlock Successful" would appear, and then reboot
5. The sim card's provider will be recognized (on your tablet) = unlock complete
SIMロック限定解除を解く場合。
To solve the limited sim unlock problem:
次に「#7465625*638*CODE#」をコール。
表示されるNetwork LockのEnter Network Lock Control Key欄に「97286414」を入力⇒OKをタップ。するとUnlock Successlyと表示される。
Next, dial #7465625*638*CODE#
The Network Lock screen with a Enter Network Control Key column should appear. Enter 97286414 then press/click ok. Once you do so, a message stating "Unlock success" should appear.
Now, I have the Overcome rom on my tab and tried this. It did not work. However, I am curious if someone with the original stock rom (Docomo) can successfully unlock this.
I do have network lock, network subset lock, SP lock, CP lock, and Data lock off but for some reason I still get the "Enter Network Control Key" message when I boot it up with another sim card.

Have you tried this one?

- If you use hexedit app, for clearer instruction do the procedure below :
1. Root the Tab, z4root.1.3.0.apk: http://forum.xda-dev...ad.php?t=833953
2. Install Super Manager as your root explorer. Enable root function in settings.
3. Backup /efs folder with Super Manager to your SDcard to be sure.
4. Open a copy of nv_data.bin in a hex editor. I installed HexEditor. Change 00181462 to 00 (note edit point is currently 01. It is the first two digits after seven "ff").
5. Open /efs with Super Manager set to Mount R/W and your modified nv_data.bin in the Root Explorer clipboard.
6. Rename or delete nv_data.bin and nv_data.bin.md5 and paste nv_data.bin (you have the originals in your /efs backup).
7. Power off the tab.
8. Insert new sim carrier.
9. Power on.

This method did work for the Docomo version of the galaxy tab. Many have attempted this and still had the network lock screen popping up.

I assume you mean did not work?
I also have a Docomo tab and am moving back to Australia after some time living in Japan and was hoping to unlock my tab. It's disappointing that the SC01C uses a different lock mechanism. I guess one of these little SIM boards that stick to your SIM to fool the device into thinking they are still on a different carrier might be an option. Selling it has become another option for me - I'm really annoyed that Samsung released this thing with all sorts of little arbitrary differences between different reasons creating lots of confusion about which roms can be run. Disappointing.
By the way I returned my SC01C back to stock, but I don't have a Docomo SIM so I have been using it WIFI only. I might see if I have another carrier SIM to try...
EDIT: I might not be much help as it appears my Docomo Tab is actually unlocked already. When I inserted an Australia Vodafone SIM in it accepted it but said 'No Service'. I would have thought it would have told me 'Invalid SIM' or words to that effect. Secondly, I tried the Softbank SIM from my HTC Desire in my Tab and it said 'Not registered on network', rather than warned me about the SIM. Is there any option I need to go to in order to test it further? I used my tab exclusively as a WIFI tab so far...
@zetsurin,
Have you tried changing the nv_data.bin on the /efs folder?
Rotohammer posted it works on all GSM Galaxy Tab.
Just be sure to back-up your original files, so you can revert it back.

Success!!
Ok, I decided to try the codes and I am roaming on Softbank with an Australian Vodafone SIM using my SC01C Docomo tab!
Firstly, to summarise everything the following Samsung codes are involved:
*#7465625# = Check the locks
*7465625*638*Code# = Enables Network lock
#7465625*638*Code# = Disables Network lock
The whole 'Code' business confused me. So basically you enter it like this:
Firstly, I entered *7465625*638*#. If I enter '505/03' (Vodafone Aus) and then 97286414 for the control key, I actually get a 'Lock successful' message, and in fact I saw some other Japanese blogs mention this. This is because that's a lock request, rather then unlock request. So I decided to enter the lock check (first code) and it confirmed I have a lock on.
Then I entered #7465625*638*#. It requests the control code only this time. So I then entered 97286414 and bingo I see the 'unlock successful' message and then the lock check confirmed my tab is unlocked.
Finally I selected Softbank for roaming with my SIM and it worked perfectly. I believe this is the correct way to unlock the SC01C we have as it doesn't have the same format nv_data (I've seen several sources say this actually).
thanks!!!
i was able to unlock it.
problem is, im not able to register to either docomo or softbank. i wonder what's wrong since i can do this on my galaxy s.
Thanks Everyone, unlock successful!

This really worked..... Thank you so much!!
works, but ony until restart
Hi!
This is the first method, that really works with my docomo galaxy tab. Thank you verry much, for the manual!
Unfortunately it only works until I restart the phone. After restart it asks for network lock key again, and I have to do the whole process from the begining.
Is there any way to make this unlock permanent?
(I also tried several other methods, like haxediting, etc,)
I have an ATT SGT with Overcome ROM, and just unlocked my TAB with an app I got on the Market called Galaxy Tab Unlock. Worked without a hitch. I had no unlock code or anything from ATT. I have used different SIM's and they all work. Also have data working with non ATT SIM's after putting in the APN's. The app, once installed, is called Galaxy S Unlock, but works with my TAB. Painless!
Yes, it worked until i reboot the tab.
no solution for this issue yet?

hello there,
my samsung galaxy S GT I 9000 says i should enter a sim network unlock pin i dont know what it means and how to go about this. Please help me. I can receive calls but i cant make calls it says Insert sim or Sim error. Please help me with the code if anyone knows it. Thanks
This is your first cellular phone - ever?
SIM unlock pin code has been mandatory in the world of mobile telecommunications for ages and are confidential personal property.
Sent from my GT-I9000
i have a locked i9000 to the uk network 3.
usually locked phones when you put in a sim card of a different network will immediately ask for a network code or something, but on putting my o2 sim card in the i9000 (that is locked to 3) i can fully access the phone i just get the "no signal" icon.
is this normal?
or i'm worried the phone is failing to pick up there is even a sim card in the slot? :/
There's a tool for unlocking I9000: http://www.communityhosting.net/sgsunlock/ (found it searching through the XDA forums).
There are a lot of related threads on XDA forums, use search function to identify them.
Good luck!
