We are trying this out. Pay only the taxes and fees (we think about $20 a month) for a year. We paid off our Verizon phones to the tune of $600, but we'll save that much in less than 4 months.

Doesn't appear to be a catch except potential data speed throttling. We paid $12 for the sim cards; they waived a $20 "handling fee".
