It depends on the type of laptop you have. Some come with a built in cellular wireless adapter, the vast majority do not. In the latter case, you will have to buy an adapter from your service provider more than likely, it will come in the form of a USB dongle, or a card that you physically install on your laptop. Once you have installed the dongle or card, you should have a slot where you can insert your sim card, after you do that, you should be able to use your cellular wireless network on your laptop.
