I got a phone for Christmas from Fido to replace my old one and everything's going fine... except for the fact that I bought one of those cardboard vouchers. I was wondering is it like a gift card where you have to take it to the cashier and he gives you the paper slip with the 14 digits on it? When I looked at it there were 12 numbers on it that I thought to be the "secret pin" I tried to enter these on my phone but It wont work. I know it's not expired so what is wrong with it?
