I just read this on BGR: http://www.bgr.com/2012/08/16/sms-market-analysis-revenue-whatsapp/. It's an article about how carriers in the Netherlands used to overcharge text messages and maintained a minimum of 90% profit margins, and that nowadays Dutch carriers are having trouble to make profit on text messages. Why? Because everyone started to use an alternative: Whatsapp. You basically use your internet connection to text. What are your thoughts on this? And do you already use texting alternatives?
