Apart from the volume of calls put through, the PwC report also revealed around 1.8 billion SMSs were sent in 2012, representing a three million rise from 2011.
Describing the rise in SMS volume, PwC’s Quality Assurance Partner, Alastair Macpherson, said outgoing SMS on-net increased from 911 million in 2011 to 958 million in 2012 and outgoing SMS to other networks increased from 316 million to 449 million.
In addition, incoming SMS from other networks also recorded increase by hitting 421 million from 327 million.
However, analysts believe with the introduction of a flat SMS rate across network, the figures could drastically change in 2013.
