Ah….you cannot shift numbers from one postpaid line to another. Apparently it’s posible...I recall it being mentioned here, but that it’s not well known and there’s no guarantees it can be done. Thew typical advice given is that you must port the number out, and then back into Koodo again. You can spin off the to its own account or another account, but the line goes whole, plan included. Or did I misunderstand wrong and you mean the family plan is with another carrier? As far as I understand family plans, you add lines to share x amount of data, and you pay a smaller amount per line...it should be fine in that the family plan retains the same amount of data, and it just goes one line smaller. That line will be cancelled once you port it to Koodo.

perfect thank you. Yes I should have specified the family plan is from another carrier. I just wanted to make sure that transferring my number from another carrier’s family plan to my new Koodo one won’t cancel the entire family plan. 

Taking a quick look at Telus’s version, the total amount discounted per line will decrease, but the overall account will remain active. This should be the same for any other carrier with family plan options.

thank you so much!!

You just need to double check how the plans are setup.

If you're on an older style share plan then things could get screwed up when you port out depending on how it's setup.

I would call your carrier just to confirm that everything would be okay with the plans before you swap.
