Can I trade iphones with someone and not change my plan?

I have a black iphone, and i want to trade with someone who has a white iphone. Can i do it without changing my plan? (i'm with bell) and i don't want to change my contract or anything.

If they are both the same carrier and use sim cards ye you cash swap phones. Just switch your sim cards

You can switch with someone who also uses bell, or you can unlock/jailbreak it.using any other phone will not change your plan unless you change it. The only time they prompt you to change it is when you do not have a data plan, but you buy a smartphone, thus they require you to get a data plan, but if you use your iphone without a data plan, that is ok, you can use Wi-Fi and you don't have mobile data.

If both of your iPhones have SIM cards, just swap SIM cards. Your plan is tied to the card, not the phone. However, if the iPhones are of the CDMA variety you will both need to contact your carriers' customer service and ask how to proceed.
