I have an AT&T Go-Phone, and trust me it's not worth it. They have 15, 25, 50 and 100 dollar cards. So pretty much your minutes are either 60, 100, 200 or 400. I am getting rid of mine and getting an actual plan on Thursday.
I have att go phone as well... and you may not know this, but there is, and has been for about 6-7 months now a $60 a month unlimited talk and text plan. Pretty damn hard to beat that.
I can't stand being in contracts, leases, etc etc. ATT is great, and the service is always in. My g/f has metro for $40 a month unlimited but she has shitty service outside of the city.
