Overview

Mostly cellular phone companies today offer data services (including email, Web browsing and other Internet applications) on their network to their consumer Smartphone devices. Unlike traditional Wi-Fi hot spots where the router must be connected to the DSL/Cable services via local loop to the central office, 3G networks use cellular networks that span large geographical areas around cities and highways you can access with your single 3G account. You can share a single 3G account with the computers by creating a Wi-Fi 802.11 network using DIR 450 – DIR 451 Cellular Routers.
