I hear ya. I find the "unlimited data" plans are just far too expensive to justify paying for. My current carrier (Verizon[0]) offers 4(!) different "unlimited" plans starting at $70/mo and going up from there. My Wife and I only have 2GB/mo plans which itself is $35/mo. Our two cellphones have a higher bill than our entire household electric/gas bill and we have a modest sized house with central air/heating and lots of TVs/games/etc.
