This is a common factor in any type of business as the most successful method of conducting business is to emulate someone who has been successful previously.

Another major step in the development of mobile phones is the advent of 3rd Generation phones (or 3G to abbreviate).

Also readily available in most mobile phones is the ability to access the internet. The technology used for this is called Wireless Application Protocol or WAP. It allows mobile phone owners to access the internet remotely and nowadays most sites are built to be WAP compatible in order to capture a piece of this market.

The latest and most recent advancement in telecommunications technology is that of the creation of Voice Over IP. Known as VOIP, this technology allows voice communication over the internet. One obvious advantage of this are that most people can use this technology very easily.

Any individual will incur several thousands worth of call charges for calling local people using other cellular phone networks as well as calling abroad.
