    It is not a Sim Lock Code it is a phone lock code i.e when you turn on your phone it asks for the phone unlock code
    Thankyou

Once you put wrong pin 3 times, your phone goes in lock mode. You have 2 ways to get phone unlocked .
1 ) find out your puk security code, use it and phone will be unlocked. If you lost puk code you can get it back calling Sony Ericsson customer service number for your area.
2) the other way is to have phone firmware flashed again. To do this you will need specific software, phone firmware image, and cable.
If you are not experienced in upgrading phone firmware  I suggest to go to a phone shop, it shouldn't be an expensive operation. If you do not do the procedure in the right way you can damage the phone.

Let me know if you have more queries

    Here is a quick tutorial on upgrading firmware on your phone, with links to firmware download pages, if you want to do it yourself .
    Here is sony global website, navigating from here you can find contact for your region and get back puk number.

    Here is instead a company who sells for $12 firmware and cable to do the upgrade on your phone, just in case you need the cable, or additional guidance.

Hi there......

well i dont think there is any other way of getting inside the phone without entering the unlock code...

but i doubt it could be done by reinstalling the phone software again..

better consult a dealer or a service center.

thankyou..

goodluck

Hi  
 if your Sim block then...............
 for a example always gives the unlock code after a year. So I have to use the phone for a year and then I can request such a code.
plz tell if your sim block,
  you can contact your telephone company on it. Ask them what their SIM unlocking policy is, if they have one.best of luck......

    There are plenty of unlocking sites out there that charge for this - but are almost always successful in unlocking phones:

    A simple Google search helps. However, here's one that say they do the W850i:

Hi,

Did you need the PIN code or the security code?

    PIN code is the code of the sim card.

    Thank you for your reply. To reset the lock code, there is no free solution. The best, easiest and cheapest way in my opinion is to use wotanserver.

    I have used in many times and it works great.

    You only need to reset security code with wotanserver. Nothing else. Upgrading or flashing firmware will not get rid or reset the code.

Please help me to unlock Sony Ericson W850i


If the phone lock code has been changed from the default 0000, or 1234, it would require the phones' software be flashed/wiped to factory default. There is no master code that would unlock the phone once a personal code has been entered.
You can try flashing the phone using the likes of wotanserver or davinci, or have it sent to sony ericsson for service.
