Help To Unlock E700

[Juca Brazil]

Hi, I need your help if possible ! I am trying to unlock an E700. I want to unclock it for all Sim Cards!!! I tried the unlock codes...*2767*688# In newer phones:#*7337#
Wen I try to type the unclock code it apears*2767*--- . it doesnt work... Do I need any special prog. or soft.? Do I need to calculate the EMEI number to get an unlock no. ?
What do i do? If I change my emei will it unlock it?
Have you any tip or information of what can I do to unlock the cell for all simcards.? I apreciate your help very much!!!Thank you very much!

If the code does'nt work you can only unlock using cable.
Samsung unlock codes are not caclculated like nokia used the IMEI number so no you cannot calculate a code for it. Take it to someone with the (expensive) equiptment.
