Free solution (SIM)unlock E900
Here follows the free solution to (SIM)unlock a Samsung E900, which worked for me.
- NSdongle crack + D800 USB datacable (PCB120BBE)
- Select C200 model
- Select right COM port (Windows XP -> Devicemanager -> Ports (COM&LPT))
(Not the COM port which you can find under 'Modems')
- Press 'UNLOCK'
And your Samsung E900 is unlock! (Well, mine was)
(Thanks!! to BouRRi GSM, who wrote it somewhere on this forum)

Phone may make a small tone and at the bottom of the screen it will read "Network Personalized" or perhaps "Network Already Personalized" F. Now input the following from whatever screen shows up: #7465625*638*00000000# (again this is a series of eight zeros) Phone may make small tone and will read "Network Lock Deactivated" G. Turn off phone

That's it. Your phone is ready to accept SIM cards from just about any GSM mobile telephone service provider in the world. If you received a "wrong password" message you will need to insert a working SIM and reset the password to the default 8 zeroes "00000000". After that you may try this process again and it should work.

Please try these codes. This might work fine for any sim...

*7465625*638*00000000*00000000#
NEXT ENTER
#7465625*638*00000000#
AND THEN *#7465625# to check the locks....all locks are inactive...these are all the locks...
network lock - inactive
subset lock - inactive
sp lock - inactive
cp lock - inactive
sim lock - inactive
activa lock - inactive
phone lock - inactive
auto network - inactive
auto subset lock - inactive
auto sp lock - inactive
auto cp lock - inactive
auto sim lock - inactive

Hope this works.Thank you.

Try this it work for me

1- Enter code *7465625*28782# without a sim in the phone
2- Phone will display "Auto Subset Lock: Activated!"
3- Enter code *7465625*28638# without a sim again
3- Phone will display "Auto Network Lock: Activated!"
4- Now insert the sim and enjoy! Phone is Unlocked!

(NOTE: When you change sim to other operator repeat this process to unlock it for that operator also)

I found this in another thread. All credits for the solution to Morfeus of the FuriousTeam!

I myself haven't got a locked Z500 so i cannot try this. But other people confirmed this as working. I'd like to hear more results on this!

I also found a list of service codes. I guess you could use some of them to enter your unlock codes manually(that you read out with WinIMEI).
