Yes, Waqas , You're right...
But still their is a competitor Wateen ... But is not an effective one, because they have setup fee and Bandwidth Limits.
Hoping Wi-Tribe to be good as Broadband Provider.

But no one knows when they are starting their services in Pakistan & in specially in Multan.

Mobilink is also Providing good Wireless Connectivity "EDGE". It has good downloading speed upto 30kbps while using any download Manager(which allow multiple connections) ..
