I get what you're doing with pricing, but I quote: "Pay for what you use. No penalties. No waste." However, for example, if I end up using 101 call minutes one month, I'll end up in the 500 minute tier where I'm paying for 399 minutes I'm not using, which sounds like a penalty and waste for me. Wouldn't just an overall flat rate per call/text/MB be simpler and more in line with what you are promoting?
Don't get me wrong, I love what you're doing. Even with the tiers, the savings overall would be very significant and I do plan on switching as soon as my contract is up with my current provider.
