I have a Evo Shift that is already flashed over to Boost Mobile. I called to activate the phone and get my Sprint phone # ported over to my new Boost account. They said they could but if I had any outstanding balances on Sprint, it could interrupt my Boost account. If I don't pay my Sprint account and it goes into collections, will it mess up my Boost account? Should I get a new number or can will it be okay to port over my same number?
