Tracfone
I bounce around with my phone service to get the cheapest deal around because I really don't use it much, Tracfone is my can't find some crazy deal fall back. There is always some sort of deal where you buy some ok phone and you get a year of service with so many hours/txt/data for super cheap.

Just the first really cheap one that popped up on slickdeals.net
I never run out of mins or txt and I'm not a big data user but another gig is $10. Tracfone buys their mins from all the big guys and which one you actually use ATT or Verizon, Sprint, whatever is just based on the phone you are using. That phone is a CDMA phone so it is a Verizon but mine is a GSM and is on ATT.
