Jazz did the first upgrade back in late 2017, and since then they have silently been increasing capacity more and more but only in Islamabad.Sorry I haven't followed this thread in a while , but I wanted to ask a question how come in my area in the middle of Islamabad zong gives 4 to 5 mbps and jazz is more than 35+mbps , I tried a few different locations and still zong was atleast 3 times slower what am I missing here did jazz upgraded its network?
There is 4G+ in most parts of Islamabad and it works quite well and it will have an edge over Zong.
You can switch postpaid ones as well, but the process takes a little longer and you have to absolutely make sure that all your outstanding dues are paid with your current network before applying to port out to another network.Also can u change networks if ur on a postpaid number or do u have to convert it to prepaid first then switch to the other network
[MENTION=63376]shaheerk[/MENTION] has converted a postpaid number in the past if I remember correctly so he can give his own personal experience.
