But most of my friends text a lot more and especially younger people. I would guess that most people who text buy the $5.00 all you can text add on. Although there are 82% of cell phone users who have never texted.
I think few people text like my wife and I do. We send about $7-8 a month in text messages, so paying $5.00 teach to buy the all you can text plan is not worth it. In that sense the phone companies are getting you to pay a lot for the first few messages, which have the highest value to you and pay nothing for the least important messages which have the lowest.
So in short they are trying to get everyone to sign up for an all you can text plan, and to get the most money out of people like me who don’t text enough for that type of plan unless the per text message is really high.
