Hey peeps dont mis guide the guy, Wateen is only on Testing Phase and its giving to its only selected Users.
Now to your Answer
Go for PTCL DSL 256kbps for 1200/- Month, I personally use it thats why im recommending you. Let me remind you their DSL has some frequent downtime but its efficient in speed. I get almost 30kpbs Speed during the day time and 40+ at night.
Relatively to PTCL, you have multinet, CYBERDSL EXTREME and WOL, BUT they do not offer you 3 months free downloading + installation + modem as PTCL gives you according to their Policy they give you 3months of free downloading + Free modem + free installation. So my opinion for you is PTCL
But the choice remains to you, so Best of Luck.
