Mobile users sent more messages with OTTs in 2012 than with SMS, according to a new research from Informa. It states that third-party app users sent an average of 19.1 billion messages per day in 2012, compared with 17.6 billion texts per day with SMS.

As is typical at the beginning of the year, wireless industry experts have been busy making predictions for 2013. It's no surprise that RCS is expected to see continued adoption this year, after U.S.–based MetroPCS and operators throughout Europe jumped on board in 2012.

Moving to next-generation messaging services seems like a logical step in the ongoing evolution of wireless technology, but it appears that some operators are leaving the transition on the back burner.
