READ THIS: FREE unlocking codes here for x495, x497, x660, t209, t509, t809 (and possibly more)

This is a re-post -- but under a different subject heading since people seem to keep asking the same questions in new posts.

Hope this helps!

I managed to make the following work for my Samsung SGH-T209 locked to the T-Mobile network. Credit goes to toolnut43 (http://forums.afterdawn.com/thread_view.cfm/462229#2821568)

Posted as follows:
Try this

1. Insert other providers sim
2. *2767*3855# wait for your phone to reboot(restart)
3. *7465625*638*00000000*00000000# (this changes network lock w/password 00000000)
4. #7465625*638*00000000# (this deactivates network lock w/00000000)
5. *#7465625# to check all locks
If all are inactive, then you are good to go.
u can unlock x495.x497.x660.t509.t809 and latest, plus of course T-209.

Enjoy!

 

I used the code that you posted for unlocking the samsung sgh-t209.
Everything worked and all was inactive as stated but I can't make any calls. When I dial it says emergency calls only. Is there something else I need to do?
