Without knowing who your carrier is I can only inform you how it's done through Verizon & the Android system. You will need to install an app. To do this. The apps on the Android system are available in free & paid versions. If phone in question is a smart phone it's very simple to download everything you need right from your handset in applications. PdaNet is the one I use on the Android system, the web address for PdaNet is junefabrics.com , hope this helps
