How can i unlock my iPhone if i dont see any numbers under Sam details?

Hi there. i recently moved to spain from Canada and i want to be able to use my iPhone here. i downloaded SAM and i have the original sim card inserted in the phone but some of the numbers i need dont appear at all. Theres no numbers under SAM details so i can't seem to activate the phone after the whole process though i have followed it step by step. can i get some help please? the last carrier in canada was Sasktel and the sim card is no longer in service.
