Just got a Samsung Galaxy Tab 10.1 and used Galaxy Tab Unlocker app to do a SIM Unlock so I can use my AT&T SIM in it but when I go to Network Setting\Mobile Networks\Network Operators and scan 2 different AT&T options show up and neither one will allow the tab to get online. One of the options says it's registered the network the other says Sim can not be registered to the network. Is there something I'm doing wrong? How can I check if the App really did a SIM Unlock? The app I used say's the SIM is unlocked. The tab is rooted and running OTA. Any and all suggestions would be appreciated.
PDF file now attached...
Please read the whole thread if you can or at least the whole OP down to the bottom before asking questions as your question might have already been answered... Thank you...

Hi guys, you can unlock you N7105 via the Samsung hidden menu. [Also works with N7100 and some Galaxy S3 (SIII) variants - NOT ALL]
#############################################
I can confirm the unlock survives ROM flashing
#############################################
Before doing the instructions below, please double check your phone that it is actually LOCKED by inserting a sim card from a different carrier/provider...you may or may not leave that sim card on the phone while unlocking
Unlock your N7105:
Click to expand...
Click to collapse
Note: your phone must be running at least Jelly Bean 4.1.1 (if 4.1.1 does not work, try 4.1.0) otherwise some of the menu choices are not present
Just dial the following keys *#197328640#
Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF > (after choosing this option, wait about 30 seconds, then go back one step by pressing the Menu button then select Back, now you are in [6] Network Lock then choose [4] NW Lock NV Data INITIALLIZ ..... wait for a minute then reboot your phone... enjoy!!! There is no confirmation on the phone that the unlock was successfull.... just reboot your phone....
To test, just insert a sim card from a different carrier/provider. If the new sim card works then your phone is now unlocked.
I have done this to my other Note 2 N7105 originally locked to Orange.....
========================================
Do this procedure AT YOUR OWN RISK
========================================
To those who were able to unlock their phone with the method above, can you please post in the thread and let us know which phone model (N7100 or N7105) you have, Country and Network/Carrier your phone was locked to...... and if I have saved you some cash, please click the Thanks button or the Donate button on the left just below my name to buy me a can/bottle of Heinekken, Quilmes, Budweiser, Fosters, Tiger, Stella Artois, or San Miguel :cyclops: ...
========================================
NOTICE:
To those having "Conditional Call Forwarding" pop up message or similar pop ups appear everytime you make a call (but they disappear within a few seconds), this is normal with an old sim card, or when using a ported number. There is no restriction to calls or internet or whatever. This is confirmed by my provider when I walked in and asked them about it. They even showed me one of their sample Note 2's and S3's having the same message.
========================================
I have mentioned in my old thread that there was a pop up message that says "Conditional call forwarding active" everytime I make a phone call using another SIm card that the phone was not able to use before unlocking.
I can confirm that this was due to my Sim card. It is a very old O2 sim card that I have used for years. I have tried that Sim card on another factory unlocked phone (Galaxy i8160 bought from P4u) and it had the same message.
Can anyone confirm that this is a full sim unlock?

No problems. I did the steps did not work. Did them a second time, looks like it worked.
Used a verizon LTE sim, but they are a CDMA carrier. First time I tried the verizon sim asked for unlock code. Tried steps again and second time it did not calk for sim unlock code. I got signal but the notification bar still said searching.
Works perfectly on the AT&T SGH-I317! T-Mobile SIM had no issues.
OMG it work im in the UK & my note 2 WAS lock on EE now im using my o2 THANK U i don't have to pay EE to unlock my phone:good:
Wow. I fricckin paid $25x3 codes for ours...
Could have saved me $75 bucks.
I wonder if this works on galaxy s3??
Thanks for sharing !

Put a sim from another carrier. If the phone does not ask for a code and you can use that sim to make calls then it worked.
just unlocked my at&t phone for free! Thanks OP!! Tested by inserting my old vzw lte sim. Before unlocking I got a pop up asking for the unlock code after putting in the vzw sim. After going though the steps it no longer asks me for the unlock code! Success!!
Hmm, this might open some very interesting options ...

Hmm, this might open some very interesting options - one of them being that the Samsung private key was somehow compiled into the modem tool inside the ROM; I wonder if that might be extracted from there and if that is Samsung-wide or just N710x-wide; what I do not doubt so much is that if that works so well then the next official ROM will remove it - but if I am right about the key it will remain valid so tools based on that could be made :good:
I can imagine that the official response from samsung on this would be "oops"! Fantastic
Thank OP for the excellent information, you just saved me $25 bucks. :laugh:
I am getting greedy, can someone come up with the steps to root the phone?
Can confirm it works on ATT and T-Mobile. I did my att one and my friends t-mobile on a few minutes ago. Thanks OP

Thanks.
Op you are legendary, can I ask how you discovered this? I'm interested in finding the other hidden codes for the Samsung LTE phones.
Work for me on n7105 from Orange, however the menus did not behave in an intuitive way. It might be worth explaining what happens/what to expect with your details.
Has anyone tried putting the lock back on? Is it possible?
Also do you have any credits to share, I like to know all the people who helped - after all; networking is the key to success.
Again, legendary. Thank you.

No problem. I just found out about the secret code somewhere on xda, but it was for another topic I couldn't remember. But I never read about it being able to unlock the phone. I just carefully played with the menu and accidentally found about it.
I have not tried putting the lock back on.... who knows we cannot unlock it again... if you want to try it, feel free and please let us know, but for me, I will not

edit:
what do you mean by it did not behave in an intuitive way?

Did a search and there's a plethora of codes here
AT&T GN2 - worked perfectly. Thanks OP!

Any comments or suggestions are welcome

Re;
I just discovered that my 2 hand phone has been blacklisted after I bought it. But the blacklist doesn't apply for the whole country...That's ridiculous...
Hello, so I recently left my carrier, Boost Mobile. So the phone is locked to their network and they won't unlock. But within my apps list is an app called Network Unlock. Any idea how I can get it so show itself on my main screen? It seems to be hidden.
