Prepaid: changing phone, same SIM, in the US

I'm on prepaid and will have a new phone soon. I understand that in Canada, you just put your old SIM in the new phone, but would that work if I do that in the US? I have the US talk and data addons, if that makes a difference. Also, I could bring the phone briefly over to the Canadian side. Does changing phones work as simply as putting the old SIM in (i.e., is it something I can do without access to a kiosk or internet)? Thanks.

What do you mean by using it in the US? If you are talking about the US boosters, no difference with the Canadian boosters.

I think he meant he wanted to put an existing Koodo SIM in a new phone while staying in US.

@qdatk: Yes, you could do it as you were in Canada, I believe.

Popping a Koodo SIM into an unlocked US phone (AT&T or T-Mobile) will work just fine. Suggest you reboot the phone with no SIM in it to clear the connection completely. It will give an error which you can ignore. Shut down and insert the Koodo SIM and you should be good to go. Might have to reboot one extra time. Don't forget to check the APN.

PS There's a limited time deal on boosters, one per category per customer, that give you twice the bang for your buck. Check your booster/top ups in self-serve.

Ah, thanks for the explanation. I wasn't sure because I didn't know if the phone itself needed to be activated on a Canadian network (since I'll presumably be roaming on a US network).

Also, thanks for the tip about boosters. I've already jumped on that!
