This is a digital mobile phone network like GSM. The main differences are that the mobile internet/WAP connection is always on, it's slightly faster than GSM and it's billed differently too (by the size of the files downloaded, not the time taken).

GSM (Global System for Mobile)

This is the digital network that mobile phones have used to make calls and send text messages, as well as the standard network available across much of the world. The data connection to the mobile internet is a phone call (similar to a fixed line modem) and it is billed relative to the duration of the call.
