Ever wonder how many texts messages (SMS) are being sent every year? Well, according to ABI Research, the estimated number of SMS messages that will be sent in 2011 will be 7 trillion. The figures include other similar methods such as SMS, MMS, mobile email and IM. The research firm claims that the reason for the large number is due to the fact that many folks in developing nations use a mobile device for emails and messaging rather than a computer. Despite the large volumes, the company thinks that the revenue will decline, thanks to commoditization. The rate of adoption for SMS use is also expected to decline with the mobile market becoming saturated. So is this good news or bad news for carriers out there?
