I had low 600's when I applied for a sprint account. I was approved under the ASL (account spending limit) program 3 years ago. It limited my spending to $200 a month. However, that does not mean you can skip a bill if your under your spending limit. They will still suspend service if you miss a month. I am still under the ASL program (3 yrs), though they raised my limit to $1200! Who has a 1200 cell phone bill every month? SPRINT=Good phones, call quality, features, and network. Terrible CS reps and long hold times though.
