i forgot to mention that when you purchase a US number on skype, all incoming calls are free. so when someone calls from Pakistan you can keep talking for hours and it will cost you nothing for the incoming (just keep track of your internet balance) and less than Rs.2 per minute in Pakistan and even less when subscribed to ptcl international package

skype is free and purchasing a US number on skype is $60 (QR.220) just once per year. you will end up paying more than this amount per month so consider this peanuts

also, when you purchase a US number on skype, you can configure skype to show your caller ID of the US number so you can give a missed call to a Pakistan phone number and they will call you back..might sound complicated but you can get up and running within minutes!

you can do all of this on your laptop or phone (if you can install skype on your phone). i prefer it on phone as you then have 2 numbers online all the time wherever you go and always in touch with your family back home

and..if they install skype on their PC then they dont even have to pay for ptcl calls (now i feel like working for skype marketing..lol)
