I have had a pretty decent experience with Wi-Tribe It has been in the family for over 7-8 years. It is a wireless, 2 MB, 100GB internet. Although, these days their services have been slouching a lot. Sometimes the modem loses its connection for two or more days. I’ve recently had a visit by a professional from their service and the guy said that there is not a single good internet connection in Pakistan as he has had been monitoring their signals at his work.
Anyways, my cousin who resides in DHA, says he has had a good experience with an internet called StormFiber, although StormFiber is a cable connection, it seems to outperform the horrendous PTCL, basically no comparison.
