SMS Helpline for Pakistan and other countries..

I wish i could implement the SMS helpline in Pakistan and other countries as shortage of blood are faced all over the world. Will need only a computer with a GSM modem and a Sim Card with a unique number and some awareness . Can setup the helpline in a few hours .. If an Operator from Pakistan or any other country could give us a SIM Card. It would be great. Hope this dream comes true someday.
