How to switch my phone plan to an IPhone?

I currently have an Android phone and I would like to switch to an IPhone. Is there a way I could stay on the same phone plan? I'm with Virgin Mobile. I know you can switch to a new phone but I'm not sure if IPhones are different.

They should be able to use the same plan. The plans themselves are not phone specific. However, carriers change plans periodically, there's no guarantee that the plan you have will still be offered.

Should be the same

Both phones look the same to your carrier, so you should be able to switch freely.
