3510i security code.

[matrulesok]

This is my brothers phone, so im not that familiar with it!

Was locked to 02, but used DCT4 calculator to unlock succesfully.Now however, with new sim card (tesco), it asks for security code.

This code is not default of 12345 and my brother cant remember changing it. I know this can be overcome using a cable and software, but i dont have cable. Is it a case of buying cable or is there another way?

Also, the old sim card does not now ask for security code, any reason for this?

Many thanks for your help! :)

Try simple ones like 00000 or something like that.If somebody changed it ,it is often a easy to remember code.The real solution is with cable!!!!!!

Tell me : Are you sure that your phone is unlocked?
Is it unlock code that your nokia is asking for?
