Skype from a mobile phone?
To make a voice call on a mobile phone is far more expensive than a data call. In general, you pay per minute for a voice call, and per meg for a data call.
Now, to make a Skype call using your PC sound card and Internet connection is basically free. All you pay for is the Internet connection. There is no ‘telephone call’ cost.
So, why can’t you write a Skype client that uses the data call capabilities of a mobile phone, thus allowing for you to make a data connection to the Internet, and to then ‘call’ another mobile phone (or a landline), but using the data connection, and not the voice connection.
Thus, you would be able to make a phone call on a mobile phone for far less that a voice call costs.
Please somebody go ahead and create a Skype Mobile Client.
