3G Technology(2)

What is required for using 3G?

·         The first thing you require is a device (e.g. a mobile phone) that is 3G compatible.

·         3G phones commonly have two cameras since the technology allows the user to have video calls, for which a user-facing camera is required for capturing him/her.

·         Unlike with Wi-Fi which you can get for free in hotspots, you need to be subscribed to a service provider to get 3G network connectivity.

·         We often call this kind of service a data plan or network plan.

·         Your device is connected to the 3G network through its SIM card or its 3G data card which are both generally provided/sold by the service provider.

·         You get connected to the Internet whenever you are within a 3G network. Even if you are not in one, you can still use 2G or 2.5G services provided by the service provider.

What Does 3G Cost?

·         3G is not very cheap, but it is worthwhile for users that need connectivity on the move.

·         Some providers offer it within a somewhat costly package, but most of them have plans where the user pays for the amount of data transferred. This is because the technology is packet-based.

3G and Voice:

·         Wireless technologies are a way for mobile users to make free or cheap calls worldwide and save a lot of money due to the latest telephony applications and services.

·         3G networks have the advantage of being available on the move, unlike Wi-Fi, which is limited to a few meters around the emitting router. So, a user with a 3G phone and a 3G data plan is well-equipped for making free mobile calls.
