As long as you payoff what you currently owe, it's not an issue. What I had trouble with was them sending me the wrong phone model, then I had to send it back and they had to restock it before I could order the new one (again). Then it removed the upgrade eligibility so I was stuck, without a new phone and without the ability to upgrade one. Their support was so terrible that I just dropped from Next entirely and went with the Apple plan, much smoother IMO.
