I am with Koodo already with a phone that is not a smartphone and want to start using a IPhone 4 that a friend handed to me. Can I buy the SIM card on the website, get it delivered to me and start using the phone after unlocking it without visiting a Koodo location ? The current plan I have is also not appropriate for the smartphone (30$/month). I am guessing I will have to change my plan to fit the ones offered to the smart phones ? Thanks.
