If I paid off my phone/contract then can I switch to a pay as you go plan? And how would I do so? Extra details: So I was recently on a plan paying 45$ a month for my phone, I didn't see a need for most features that I had so I decided to cancel my plan early by paying it off. I did so and now I am wondering if I can use that same phone and sim to get a prepaid card? And how would I activate the phone using the prepaid card? Thanks for the help!
