3G is the third generation of wireless technologies. Unlike previous wireless technologies, it comes with greater improvements and enhancements such as high-speed transmission, advanced multimedia access and global roaming. 3G is widely used with mobiles as a way to connect to the internet and other IP networks in order to make voice and video calls, download and upload data and browse the internet. 3G allows for higher data speed, better audio and video streaming and has video call and IPTV support.
In order to use 3G technology on your mobile phone, the handset needs to be 3G compatible and you need to subscribe to a service provider to get 3G network connectivity. the 3G connection is provided through the simcard in the mobile you are using and you can remain connected to the internet whenever you are within 3G coverage area.
Even though 3G can be costly, this technology can allow to you to save on other things e.g. making cheap calls by downloading a VoIP application on your mobile phone.
