Phase II Of Mobile Numbers Migration Completed
A good write-up from PTA on mobile number migration work, currently in progress. See my previous posts here and here.
Pakistan follows International Telecommunication Union (ITU) -T standards E.164 for geographical national numbering plan that includes local loop & cellular mobile operators. The cellular mobile numbers are identified by means of 4-digit separate access code which is known as NDC (National Destination code) i.e. 03xx (x=0-9). The first 50 codes are reserved for Cellular mobile operators. Each access code has the capacity to accommodate 8-million subscribers excluding level “0” & “1”. This means that subscriber number consist of 11-digits i.e. NDC & 7-digit number starting from 2 to 9. In Pakistan cellular mobile numbering plan is based on geographical boundaries that limit the utilization to 50-60% of the numbering space available against each NDC. In this scenario, each cellular mobile operator requires multiple NDCs to accommodate their growing subscribers.
To provide more numbering space, a public consultation process for 7 to 8 mobile number migration was started in 2007. The consultation paper was circulated to all stakeholders and it was decided that the current mobile numbering plan i.e. 0300-xxxxxxx will be changed into new mobile numbering plan i.e. 030-0xxxxxxx. The mobile number migration is planned to alter minimum changes in the existing mobile subscriber numbers, as there is shift of 1-digit from mobile NDC code to the subscriber number. Except CMPAK [031], Instaphone [036], & SCOM [035] the numbering plan of remaining cellular mobile operators will remain the same from subscriber point of view. The dialing format of Mobilink, Ufone, Telenor, & Warid will remain the same but the changes are implemented in core network. This will increase the current numbering capacity by 10 times which is enough for next two decades in Pakistan.


Mobile Number Portability (MNP) has finally started in Pakistan during this week of March 2007. For background and history see my 
There are times and places when and where a phone ring is not desirable: Cinemas, places of worship , exam venues, libraries etc. A cell phone jammer is an instrument used to prevent cellular phones from receiving and transmitting the mobile signals to a base station. By broadcasting on the same frequency as a mobile network they block signals, leaving phone users with a “no signal” message. Effectiveness of a jammer ranges from a few meters to kilometres. A portable mobile phone jammer is shown on the left, courtsey of BBC.


MNP is the ability of end users to change service providers, without changing their mobile numbers. MNP is considered a major achievement for any mobile market and it is anticipated to shake things up in the already heated mobile market. Research from Japan and India indicates that about 30% of subscribers would switch providers if they could keep their numbers. MNP poses many technical and administrative challenges for the operators but provides a competitive landscape for consumers and operators. Usually MNP increases the potential of churn (loss of customers) thereby forcing service operators to work hard to retain their customers. MNP helps the best company to win.
