Hi there, I'm looking to make the jump from Bell to Koodo. My understanding is that if I "unlock" my phone from Bell I can still use my same cell phone number. I currently use a Samsung 5 neo but I just recently bought an iPhone 6s second hand it's unlocked. The sim card I have with Bell doesn't fit in the iPhone 6s, so in order to use it I would have to buy a new sim card anyway... So my question is - is this all doable? To get to use my iPhone 6s with a new carrier, Koodo, with a new sim card AND still have my originaly phone number?
