Hey guys, I need some helpful information to clear my doubts. I have a Samsung Ace as of now( bought it for $0 from Kodoo last year) and i want to get the new Moto G from Kodoo. Is it possible for me to exchange Ace with Moto G using their tab system and not paying anything? Please let me know as i am a bit bored of the Ace and want to try something new without paying for it!! Thanks.
