Hi,
I have been struggling to unlock z550a (Fido, Canada/ CID51) the cheapest and the easiest way possible.
I have already tried D-client but it isn't compatible with the phone.
I have heard that unlocking was possible through SE Tool but it seems as if SE Tool is not compatible with Winodows Vista because I am having issues opening the program.
Sorry I am still new to this. Your help will be much appreciated.
Thanks
