I have an iPhone and currently pay for 1500 txt messages per month at a rate of a cent per message. The problem is, I send and receive on average 350 txt messages per month. That means I pay roughly 4 cents per message. One could argue that I pay 4x the amount for txt messaging over someone who causes more data congestion by using 1500 txt messages per month. Clearly, something is wrong with this picture. What are your thoughts?
