Samsung Mobile Phones

Does anyone know of an unlock code for a Samsung e315?

I tried to get the code from T-mobile but they won't provide it b/c my acct. is past 90 days of cancellation. I tried Samsung but haven't heard from them yet.
I've read some forums that provided different codes (*#9998*3323# was one I remember). I tried them and they didn't work. I know I could pay for it but that's just not in the cards right now. If anyone can help out that would be great. Thanks.
I am trying to unlock the phone so I can use a SIM card from a different network.

Do you mean to use another SIM card on it?
If so, only T-Mobile can give it to you for free, since the code varies by IMEI number of the phone. Keep calling and telling them to unlock it, their terms used to be that after 90 days and if your account is in good standing they will do it. Haven't heard of that changing. Keep calling them, eventually you'll get someone that'll help you, if not ask to speak to a higher up, more than likely they'll say you have to wait, but that is fine. Persistence is the key.
Good luck.
