Hi all, I need a cell phone now as I have my Sony xperia arc from 2011, I now on the AT&T prepaid, and I love the network as it strong here in my city, I would told you what I can afford I can afford about 25-50$ monthly or 400-450$ to buy it cash, I'm going towards the Iphone 6 plus as I don't convinced with the 6S, what is your recommendations?
