Ive heard that Wateen provide really good cable service, but its such a shame that its only available in specific areas. I think it should be made available in all areas of Lahore, Karachi and Islamabad as well as other parts of Pakistan too.
Even on Wateen's official website they only say that they provide 90+ channels and 5 inhouse channels but no mention of which channels they provide. It would have been better if they provided a list of channels on offer at least.
Wateen Cable TV is available in Lahore, you would need to check with the sellers in Lahore whether Johar Town is included in their location for Wateen installation. Although I am quite sure that there should be no problem in getting the cable connection.
