If you want to purchase the iPhone SE in Tab Small. I believe the only option you have would be to visit a Koodo store and it would be $120 upfront for Tab Small and there is a $10 tab charge for 24 months.
Thank you for your answer! I went to a store already and I was told it could be done online. I'm supposed to get a 150$ discount if I make the transaction online (instead of a 50$ discount in store) so I would really like to buy it online if it's possible.
