Cell phone operators in Pakistan are investing other $100 million in order to meet a October 2006 deadline laid down by the Pakistan Telecommunication Authority (PTA) for the implementation of mobile number portability (MNP), officials said. The PTA last month asked all the cell phone operators and Pakistan Telecommunications Corporation Limited to speed up the process of upgrading their switches for the early implementation of MNP, a system which enables a mobile phone subscriber to carry the same number while changing the cell phone operators.
