The text messaging charges post garnered quite a bit of discussion, so here is another post with two questions to clarify the discussion and keep it going:
1. If you asking whether you want to receive a message is such a good idea and then not charging if you reject, why don't the cell phone companies adopt this? Why would they still charge for the message?
2. Garrison pointed out that cell phone companies in Europe charge for more services than in the US. Why do you think that is?
Again, I urge you to think from the perspective of the cell phone company constrained by the consumers and competition.
