I noticed in this months FMCA magazine that "CallATN" has a one page advertisement for cell service. Anyone know anything about them? What network do they use? The plans seem to have good prices but is there a catch, like a very limited coverage area? What am I missing?

They use the sprint network.....same as boost mobile and nextel , I presently use boost and it not bad and was thinking about switching to walmart because they use verizon and att as there carrier.........pretty much they all cost 50 with there unlimited data plan....with no contract
