Yes. Buying a new phone in another Tab is considered as an upgrade.

If you still have 12 months left, then you need to pay back the bonus to start a new Tab(24 months)

Yes, getting a new phone is considered an upgrade so you would be charged the remaining tab bonus if you got a new one on the tab.

So if I buy a phone somewhere else, can I activate it and use it with Koodo?

Yea you can just swap the sim card from your current phone to the new one!

Yes.

In this case, you don't have to worry about pay back the bonus. It will decrease every month for another 12 months to $0.

Just a couple more questions so I have things clear.

Is there and activation fee if I buy a phone from someone else?

Can I keep my same plan with a different phone?

Thanks for all your help! 

If you buy the phone from someone else then nothing changes to what you have currently. No activation fee, same plan.

Just to make it clear though, someone else doesn’t mean Walmart who sells Koodo, or Best Buy who sells Koodo.

As long as the phone is bought outright, or financed through a different way, then you’re good.
