Hello! I have a CAN Data 300MB 300 min Plan at Koodo. I am only living in Canada until the end of December, but I am interested in changing my iPhone 4 to a brand new iPhone 6 while I am here. The simcards are however different and that is what I'm wondering: can I change my simcard into a nano simcard at Koodo without getting a Tab Plan which would lock my phone for a certain period of time? Is it possible? And also another question: how do I end my plan? I'm not gonna be in Canada after December 30th so I don't need a canadian phone plan after that, either.
