Can I use one of my old cell phones because I currently don't like the one I have?

Question

I have U.S. cellular as a service, I don't know if that matters just letting you know!

Answer 1

Which phone model, which carrier?

Have you tried putting the SIM in the new phone? It either works or is says something relevant that we should know in order to help you. D'oh!

Answer 2

you can

but since us cellular doesnt use sim cards you will have to register your phone on your plan online or in one of the stores
