Get Zong 4G Internet Sim from Zong Franchise. Activate 3GB/ 3 month internet pkg from framchise in just 1000 rupees. You will be given 3GB every month. I have found this package cheaper. As you know zong has a wide range of network in the country with outstanding speed. Remember one thing, you will not be allowed to get phone call over that sim. That sim is used for internet only.
