Any Good Speed internet Provider in Karachi

Hi, I am PTCL broaband and Evo nitro user,

I have Broadband 4mb and Evo 9.3 Nitro, I was getting very good speed from nitro upto 950 kbps on IDM consistent, but since last 2 week my Evo Nitro speed is totally down is there any good alternative for Nitro I want high speed as i used to download xbox360 games 1080p movies etc . Thanks

Wait for few days there might be congestion on the tower as I have same issue but yes Nitro Rocks

@rockz so in how many days your problem was fixed?
