Today I went to PTCL exchange and submitted DSL disconnection application along with router, last bill and CNIC copy.
They also asked me to fill out form and gave me receipt with stamp.
Tomorrow I will ask Fariya Cable guy to come and install cable net although Wi Tribe is also an option but I don't know which one is better among these too. A couple of guys near my home are using Fariya and they say it is working fine.
I also emailed Connect Communications to enquire if they offer internet in my area but being a typical Pakistani company, they have not replied to my email.
