But for now, SMS still account for lion’s share of revenues
Only a third of Britain’s 1.2 billion phone messages will be sent this year  by traditional SMS as mobile apps become the preferred means of staying in touch. That’s the conclusion of a Deloitte Technology, Media and Telecoms (TMT) survey, which says that a seachange in consumer behaviour towards instant messaging (IM) is sounding the death knell for text.
But, it says, though OTT mobile apps like WhatsApp and Viber are becoming increasingly popular, SMS still dominates the amount of earnings generated by mobile messaging.
It will still account for an estimated 98 per cent of revenues this year .
Commented Ed Shedd, Deloitte’s head of UK TMT, “Despite the growth in instant messaging services, we expect text messages to generate more than £60 billion globally.”
“This is about 50 times the total revenues from all instant messaging services.”
Worldwide, Deloitte predicts that 50 billion instant messages will be sent every day this year , more than double the 25 billion SMS messages that will be sent.
In a side note, Deloitte also predicts that more than half of UK consumers will own or have access to a tablet by the end of this month [January 2014].
