How to unlock Samsung Jack,Epix,Omnia for free

by Ruchira on April 14, 2011

90% of people coming to this blog comes to read how to unlock huawei modems 🙂 that post is viral and I’m getting about 1000 views a day on that post.

So heres another unlock process! This time its windows mobile! Using this method you can easily unlock AT&T or any carrier locked Samsung Jack I637  , Samsung Epix I907  and Samsung Omnia I900

Traditionally to unlock those phones you need to get unlock code. If you are in USA AT&T will give you the code if you called them but for other countries its not possible. You can get unlock codes on ebay for about $1.50 and upwards but lets save it and go DIY,


  • This wont work for Samsung Blackjack II I617
  • It wont make harm to your phone but if it doesnt work 2 times dont try doing same 3rd time because it may lock you phone and may not be easily unlocked thereafter!

Power on your mobile phone without simcard and type *#7465625# on home screen. It will show the lock status. And its just for your information

In this method we need to fool the phone. I mean we need to enter a lock code to it so even if that already locked our lock will overwrite the old lock.

  1. From the Today or Home screen, type in *7465625*638*#

It will prompt you a dialog contain 3 boxes.

2. Enter the Mobile Network Code (MNC) in the 1st and 2nd field= 310410 Thats AT&Ts network code and it will be fine for all networks. When entering it you might only see asterisks but enter it correctly and it wont be a problem

3. In the last field, enter 12345678  Thats our unlock code! You are fooling your phone 🙂

4. Then press OK and it will tell you that sim lock is enabled!

Now here is the real unlocking part.

1. From the Home screen, type #7465625*638*#
2. Enter the unlock code we assigned earlier 12345678 and OK it.

Voila your phone is now unlocked 🙂

It does not work on my Samsung Jack w/ WM 6.5 🙁
It keept saying wrong mns number to the point where I locked my phone & had to go to AT&T store & got new SIM card.
If anyone knows how to unlock for Samsung Jack w/ WM 6.5, please post it here?
Thank you for helping… appreciate it!

Is there any update or way to unlock a Samsung Jack running WM6.5? My handset has WM6.5 and I am not able to find the WM6.1 version. Thanks in advance for your help.
