A 3g cell phone is not the same as using a WI-Fi gadgets which can use free hotspots for web surfing. If you have a 3g cell phone, you have to subscribe to the service provider for network connectivity. This arrangement is known as data plan. Devices that use 3g network connect to the network through the SIM card especially for a 3g cell phone. The 3 service is available as long as you are within range of the network, however its still possible to use 2.5 and 2g network incase you are not within range of the 3 G network coverage. The 3 network has the advantage of being available on the move unlike Wi-Fi which makes it convenient for a 3 g cell phone.
