I've used both Warid's 4G LTE and Zong's 4G LTE. I noticed that warid is providing 4G coverage in almost all areas of Lahore. On the other hand, there is very limited coverage of Zong 4G.
Warid is offering speed of up to 15mbps (checked with speedtest.net) during day time and up to 20mbps during night.
While zong's 4G speed is never more then 7 or 8mbps.
Both companies are providing same LTE, then why is there such a big difference in quality and coverage? Any idea.
