The first SMS was allegedly in December 1992 by 22 year old Neil Paparoth, an engineer who used computer for sending a text message.
Three years later a phone provider started supporting SMS, customers sent 0.4 SMs per month. By 2009 5 trillion messages were being sent annually by mobile.
The problem arising with texting now is the excessive use of the mobile phone by both the teenagers and terrorists.
We cannot stop the usage of the texting in the terrorist activities but surely can control our kids from excessive texting before it turns into a phobia.
