The mobile phone subscribers in the country have made more than 192.9 billion minutes per year voice calls to landline and other cellular networks which is expected to go up further during on-going year. Touching of over 16 billion minutes (voice calls) per month mark last year is due to unlimited and inexpensive voice bundles being offered by mobile phone operators, showing an increase of 40 percent, Pakistan Telecommunication Authority (PTA)’s report revealed. It said this voice traffic translates into an average of 528 million minutes per day or 22 million minutes per hour or 366,666 voice minutes per minute. In other words – on average – there are around or over 366,666 mobile phone users on phone doing voice calling every time. Every mobile phone user on average make 141 minutes of voice calls every month which can be translated to an average of 5 minutes of outgoing voice calls per subscriber per day. The report said the substantial increase in cellular outgoing traffic is mainly attributed to low-cost voice bundles which allows virtually unlimited voice calling on local networks. Furthermore, the decreasing call rates – during year 2011-12 – is said to be another reason for such increase in cellular outgoing traffic of Pakistan.
