China Mobile Pakistan has invested more than US$2 billion so far to build up network infrastructure in Pakistan since 2008. Zong has built the second-largest cellular network in the country with over 15,000
base stations. To
go green, Zong has installed solar powered cell sites in various locations. It has country's largest solar power telecommunication network. Its
network base stations, microwave links, IT support and transmission towers are maintained and provided by
ZTE Pakistan.
Radio frequency summary Next generation mobile services On 23 April 2014, Pakistan concluded the auction for the next generation of mobile spectrum. Zong paid $516 million for a 10 MHz spectrum in the 2.1 GHz frequency range for 3G and a 10 MHz spectrum in the 1.8 GHz frequency range for 4G, making it Pakistan's first 3G and 4G operator.
LTE Advanced (4G+) Zong has refarmed 5 MHz of its 2100 MHz 3G spectrum for 4G. They are currently deploying (via carrier aggregation) 15 MHz of Band 3 (1800 MHz), and 10 MHz of Band 1 (2100 MHz) for
LTE-A.
5G Testing As of August 2019, Zong is the first of three mobile network operators in Pakistan to successfully conduct
5G trials. In the trial, speeds of up to 1.14 GB/s were achieved.
5G launch In preparation for the launch of 5G, Zong acquired 110 MHz of spectrum in the 2026 NGMS/5G Auction including 60 MHz in the 2.6 GHz band and 50 MHz in the 3.5 GHz band.
Number scheming Zong uses the following numbering scheme: +92 3 1 N1N2N3N4N5N6N7N8N9 +92 3 7 N1N2N3N4N5N6N7N8N9 Where, 92 is the
ISD code for Pakistan and is required when dialing outside the country, 3 is the mobile access code, and 1 or 7 are the prefixes for Zong allocated by
Pakistan Telecommunication Authority. Omitting +92 would require 0 instead to represent local call, hence 031/037 are the general prefix and N1N2N3N4N5N6N7N8N9 is the subscriber number.
Zong Fiber-to-the-Home (FTTH) Zong plans to launch
Fiber-to-the home (FTTH) Broadband internet. Initially the service will only be available in select areas of Karachi. ==Marketing==
