if you can't order online then you are done. they are only available online.. theese cards usually are shipped from china.. and you have to order on websites..
theese kinda of cards are not for sale on local stores because obvious reasons. (copyright..)
your only hope is search on your country ebay\craiglist equivalent websites, or ask a friend to order them for you.
if you can't use paypal (or equivalent), you are out of luck with buying the card from other people here...
and most of people here are from usa or other countries like canada germany, brasil, italy, japan etc.. never seen someone from pakistan on this website..
TL;DR without paypal equivalent or credit\debit card that can purchase stuff on the internet you are out of luck.
