Hello, I have a Samsung Ace II and I got it unlocked before leaving Canada. I am now in Europe and have purchased a SIM card here but there is no prompt to enter the code given to me by Koodo nor will my phone recognize the new SIM card. I am not sure if my phone was actually unlocked (I was charged though for it) and am not sure how to get my new SIM card to work. Please help. Thank you.
