Thought this might be helpful to someone, Transworld is now available in Karachi Admin Society i.e. KAECHS including adjoining areas such as PECHS Block 6, etc. Had them installed a week ago. Service is excellent, absolutely top-notch especially compared to my earlier frequently disconnecting PTCL. Customer service is excellent too, I was given a timeline of 15 days for deployment but they said they'd be looking to install it within 10 days. They were spot on, installed it on the 10th day. I subscribed to the 50MB package. Their offer was to just pay upfront installation fees i.e. Rs. 17k (incl. tax) and you'll get 3 months of free internet, after which the usual subscription fees would apply. However, this offer is now apparently expired.
Another friend at KAECHS Block 1 installed it, subscribed to 30MB package, he's satisfied too. Another friend at PECHS Block 6 installed it, subscribed to 50MB package, but he had some issues regarding the service. He called them and the very next day a guy from technical services was at his doorstep with his laptop to resolve the issues. Hope this level of service and customer support remains intact. Miles ahead compared to the usual support I got from other ISPs.
