Nokia 6820 cant unlock with calc

[wirelessxpert]

I have a nokia 6820 locked to AT&T USA I have tried the calculator codes to no avail. Is this phone unlockable via calcllator or does it need cable solution? any assistance you may render will be greatly appreciated.

you are probably doing somthing wrong, ive already unlocked 2 of those with a calc program. Make sure you select the right options.

first check if phone is really locked e.g. with a t-mobile usa simcard

unlock: 31038, ASIC 2, Boxkey 32835
