You cannot reactivate a smartchip aka sim card...once it's deactivated for security purposes they are not reactivated. You will need to get a new smartchip

i would invest in a leather glove. this will help when gripping this phone. if this phone has any voice command abilities, i would program it to dial in this manner.

try 1234 or 12345 or something like that, if its still the default, if its been change, all you can do is reformat it to a cellphone shop.:)
