I went to a shop far away from my house to buy a 4G data sim card. It was cheap and cost me about 250$ for 15 months for unlimited speed and data. The shopekeeper configured it wored directly. I put it in my protable wifi hotspot that provided a network for nearby devices. I made use of it to connect all my device to the net whereever I want to. It becomes easy to connect and don't worry about further charges. I forget to mention that i wait there about two hours to open the shop. It should be opened at the same time as I came.
