Transferring a phone number to Lucky Mobile

[Compumom]

We signed up for Lucky and got our SIM cards at The Source locally, and the salesperson told us we cannot transfer our previous phone numbers (with Bell Mobility) to Lucky. He said it is impossible, but this website says otherwise. Even though he set up our SIMs with different numbers, are we still able to request the transfer of our original numbers? How do we go about it?

I was with lucky few years ago and then went with bell. I want to return to lucky but I'm wondering if I buy a 2nd sim card will I be able to keep same number because my number was once associated with my previous lucky sim card.

As said in the title, I am having trouble figuring out how to transfer my old number to be my new current number with lucky mobile. I have already chosen a new number with lucky mobile so I cannot transfer numbers when I sign up for lucky mobile, because I’m past that point. If anybody has some guidance I would greatly appreciate it. Thank you
