Hmm... I might have to look at those Net10 plans. Thanks for sharing that, John! They have a plan for unlimited everything with no international calls for $45/month. That's a little more than a third of what I pay Verizon (though I have tethering with Verizon, which Net10 doesn't allow).

They're a little unclear about the other plans, though. How does data work on that 750 minute plan? It says "auto-refill," but what the does that mean?
