Sorry my friend, You cannot get any free unlock codes for Nokia 1208 online. Most of them will charge you anything around 10quids online to get it unlocked or you can get it unlocked in your local market for 5 quids at the most which would be cheap.
I believe the calculators wont work for these phones.

you may try some default codes!!!!!
