Porting over number from Bell to Fizz, do I need a new sim and will I lose the cheap pricing ?

The title is self-explanatory, but fizz customer support is not helpful at all. I found out that I need to have a new sim so I can port over my bell phone number. So in the end, my account will have two sims and I have to cancel the original sim that I had since November 2018. I was told I would lose the cheap introductory pricing but then I was told that the cheap pricing is until April 2019.... so I am confused
