i went by the witribe office and got the 512kbps package @ 850 which was activated in about 30 minutes. at my office i get about 1/2 bars (signal strength) and my speedtest came up with 520kbps download speed. at home i get full signal strength and the downloads are again at 520-530kbps. browsing is generally good as well, in the morning i had an issue while checking my account status on the witribe site. for whatever reason the internet connection went dead, i couldint ping anything or browse any site. and i kept getting redirected to some weird wi-tribe.net.pk survey site when i tried going to wi-tribe.pk
the customer support didn't answer the phone twice and finally i tried again a couple of hours later and they were able to quickly resolve the issue.
i'm just 3 days in but its seem like a decent service.
