The new 3 Skypephone S2 has built-in modem drivers, meaning it can act as a dongle and give users internet access when on the move.
Users need to plug a cable that comes in the box into a laptop, which will then get them onto the internet.
As a result, there is no need for a fixed-line or a Wi-Fi hotspot.
The 3 Skypephone S2 boasts free Skype to Skype calls and Skype Chat to anyone in the world whether they're on PC or mobile.
The phone integrates Skype contacts into the phone address book and gives users access to presence information, call logs and Skype Chat.
Kevin Russell, chief executive of 3 UK, said: "Using the internet on your phone has sometimes been fiddly or complicated because of the limitations of traditional interfaces.
"With the 3 Skypephone S2 we've taken our long experience of putting the web onto mobiles and have used it to create a new concept in user interfaces."
